 So, okay. I'm very blessing, sorry. Thank you very much for coming today. And my name is Masafumi, and I'm talking about, you know, mini-card type computable for your business. And this is my profile. And I used to be in the contribute open-slice project, and contribute open-slice projects. But now, I'm now leading the Raspberry Pi community in Japan and volunteering for Raspberry Pi Foundation since 2012. It's been almost seven years. And in other sites, I also contributed OpenStack and home business, and now active committed OpenStack Foundation and using OpenStack and infrastructure for an automotive business. And now I'm innovators, so I encourage the business startup of business. This is my leader. And you can see Raspberry Pi OSHA forum in the Japanese category. It is my, oh, oh, oh, it is my. And as I'm conservative, and you can see in my pictures and upside. And before my talk, and some of you know, see this. Sorry, upside down. And this one. Yesterday at 2 p.m. in Chinese time, and the Raspberry Pi Hall and the ladies thing. What? Finally, and you can see the power of spec. And more memories and in improving the spec and you can see on the website. And frankly speaking, I have been evaluating for two months and to evaluate this Raspberry Pi. And the whole benchmark and the whole some spec check and some bugs on it. And also it works for good. And it needs to be improved. Need to be some improvements and improvements to implement all that. And that almost works fine. And sorry, and I have no time to end this. And something was showing video from Raspberry Pi Foundation. So, and you can, and please check the Raspberry Pi website. And you can see a brief video, and you can check the fast spec on the Raspberry Pi who have. And the Raspberry Pi Foundation made a video for users. So, you can see the video on the website. This is, and this is, and so, oh, sorry. This is on the, at the grounds on the Raspberry Pi thing, all things. And this is analog audio inputs. And CPUs and ADS and AS-70 to latest processor. And you can have a whole gigabyte at max. And you know, Raspberry Pi 3B Plus used to have and three, one gigabyte at max. But on the Raspberry Pi whole, and now on the whole gigabyte at max for 64-bit and applications. And also, you can use in the old 32-bit applications, Raspberry applications on that. And it is a good spec in both 32, 64 applications. And the point is, and so, and independence and ethernet and USB controllers. And Raspberry Pi whole have an independent and gigabyte, gigabit, ethernet controller and USB-free controller that is used for, and the full max speed for the ethernet and the USB control. And I have checks on the benchmarking on the ethernet and can be used on the 970 megabyte per sec. And it is very faster than the old Raspberry Pi 3B Plus. Oh, sorry. And USB ports and Wi-Fi and Bluetooth ports and ethernet ports and USB 3.0 and you can use in the old USB 2.0 ethernet ports and the PI with a compassable HDMI and through both HDMI and you can use, and you can plug in the two and the Hokey and the display at max. And the beautiful Hokey cars and using on Raspberry Pi 3. And you can also use the POE heart and power ethernet. And the problem is changing on the Raspberry Pi 3B Plus used to be on the USB and the micro. And now Raspberry Pi 4 has USB-C on the power. And it is used for more parts. And so please be careful. So it is on the changes and we have a three-point USB and the C and the plugs. And the stickers and the USB ports. Wi-Fi module and this is on the front. So it is on the, oh, sorry. It is, and it introduce Raspberry Pi. If you have any questions, please let me know after the session. So, and so maintain and today is, and what is the mini-card computers? And so to be kind and you know on the credit card. So it is very similar to and the size on the, almost on both, both as a credit card. But later you know on the AI and the use for such a board and bring some changes. So it's getting bigger and it is as this board and which is a Pico ITX form factor and more. And now on the, and the Core i3 architecture base board and that is, that has all and they also, and it is a Pico ITX architecture on that. And it's getting bigger regularly. And this is a core, you know, on the Google and the stick board. And it is on the Google safe and it is, and it's all same on the Raspberry Pi zero. It is on the useful and on the Raspberry Pi zero, but something is connecting and they call out and they have a USB C, but Raspberry Pi have a USB micro need to something change and need to use a connector cable. And the more and they might be some and not good performance on that, but it is a useful Google safe. So far there's a mini computer and the small and factors and card size and small and the embedded and with the computer you're from the ITT IoT and it is a very good and important point in chip. And I sometimes discuss some vendors on the 5V chip and Raspberry Pi is on the target for a safe in a 35 years time and even for a Raspberry Pi 4. And it is on the strategic prices. So it and the first price is important most of the vendors. And it is an important point on the chip. And run through distributions and the most on the board is now on the ambass and the full distribution OS like Debian and BSD on the, but hopefully we don't have running on it. And my computer is on the F-Bone for PC and sometimes and presenting and some confidence about the Raspberry Pi history. It is all on the chip and it is all on the chip and it is all on the chip and it is all on the chip and it is all on the chip and the education and the programming. And later years, PC is very expensive and so it is very hard for hacking. So now on the PC, you know I have using of MacBook and it is for the only presentation and that's something something on the web and the web and such like same. And, you know, and the socket is now getting smaller and the chip faster and cheaper and rapidly. And I haven't heard from the Raspberry Pi Foundation and about the benchmarking and the deeply in the Raspberry Pi whole, but it is on the close to something like on the latest PC and more now it is very cheap. And you know, smartphone is very, very on the faster and it is very enough to use on the daily life. Compute using and Raspberry Pi and now, you know, and open for door and something like on the computer use. And at first, they are used to, they use it all and keep education or programming but then they and Raspberry Pi and Raspberry Pi who are using and the whole end of it computer business and the two and the industry business. And it is on the dynamic exchanges and that's because of the, it runs on the full time, full distribution OS. And for the concept, it is faster than it is on the whole first educational use and the cost and the target price in the textbook and it is for the new views. And I've heard in some of the college, some of the high school and the high school and the whole using and what and Raspberry Pi useful and it is and something like trial and the students break the PC. And what's breaking the PC? It runs how it works. Ah, sorry, they run how it works. So and the teacher tells me and the breaking PC, very important to run and the PC and the deeply. And literally and the whole thing was like China, you know, and Nanopi or the banana pie and the, sorry, they are tall model now, literally. I don't know in detail. And now for very brilliant, first of all, Evan and Tommy and the, they are many more fake, but and we don't care. And it is very important and growing growth and the big market for the, and such a mini-card computers. So it is and now and they are many more you can see and the card size computer around the world. And this is more variations or Raspberry Pi, my friends are taking a pics and now on the blogging on the hip website. And this is, so and I should take and we should check and the deeply and so something like hardware things and the some of, sorry and may ask you and you have some Raspberry Pi or Raspberry Pi similar board, let's see how it is, no? Oh, okay. So first of all, and so sometimes and you know, and it annoys the SD card if it to break. So and Raspberry Pi foundation and the Raspberry Pi engineers and has been ever rating and SD card things and because of the, it's really weak and very nervous to the voltage inputs and less more and a sort of issue on relics. And so and Raspberry Pi and the BPS and the carrier service are checking on the SD card issue and they say it break very easy. And we should take and use another way for that. So and the SD card is a very, very easy to broken so you should check and the what and the use and you like to and the useful and because and the SD cards and the very easy to broken for that and the EMMC and now on the Tinker board and the some of the board and the included generally and because and the assistant and they know and the SD card issue. So they prefer to use on the EMMC card inside. So on the and it is good local function but low speed and low cost and sometimes high cost higher than on the EMMC card and now on the USB and the disk and you can use and the boot and boot devices or many more on the and the EMMC and the sorry and the card size and the computers. So and you can and the and you can use that. It is very easy way and what depends on the speed controller and so on the if you and the so and use the many more and the and many more on the PCs are sorry cut size PC on it and the you and you should and the you should better to choose on the and the PXE on the network with network option and the Raspberry Pi on the other board health and because on the sorry and the and the and the so and the USB Pi and the so and the GPS carriers and the and the and the has the conclusion for last week and the they and the it might be better to use on the top working booting and the thing and thing using and many more on the Raspberry Pi as a cluster and yesterday and the Aoyama-san and the and the hard LED and the and the about the Raspberry Pi cluster on the and for Kubernetes and it might be better to use a base key and the not to use on the and the SD card here and the just before and the here I and discuss within and the here and the to me and the say and the SD card sometimes broken and the for using and the SD card and the SPI all depends on the use and lobsters and the as sometimes on the and the annoys or lobsters and the because some of and the both still weak and the some for some use and you should take on the and the use and the lobsters and the before using it and the Raspberry Pi and the is if baby and the and the tough and the because only and the Raspberry Pi in a supportive and the children treat is roughly and the that is and the and the to children and the sometimes and the through England and the PC game controllers and the you know and the throwing and the and the game itself and so this thing gets stressed and the children and the throwing something for and the whole then the stress so and they and the Raspberry Pi supporting Raspberry Pi supported a supposed to support the and the so children and the to throwing on the board and it is very tough but and the some and the board might be fried so and the and the unexplained momentary power I mean and the and the so many of both supporting and the support store to and the use and the five both to ampere and the for the hardware but and the some battery and the and the provide and the incorrect and the both and the amperes and that is and the some board provides 1.9 amperes I say some some but the something some of us and the and the provides 1.9 amperes other and the AC battery adapters provides and the 2.1 amperes and other 2.2 2.3 and the and that and sometimes and the AC adapter provides and the in correct battery that and the break is a both and the I met and the issue and the HPC board on that so you should and the so please and the care and the for using and the and the board and the and the providing so that the AC to the both and the you should take very carefully and so such a thing and the such a thing so the before using such a musical cars I bought and the color and the kind even not easy to update and not if kind of update is still not easy so and the you and the almost the new users and the and the for upgrading and the up to get upgrade or up good up to get and this high ramp update upgrade but and the almost and the such a concept was need to and the so update and the you boot the and the TV and the so and the in manually and the it is very difficult sometimes and the check and the update also and you know the FF is manually so sometimes I know it was but nothing by the not and the care about that but is and the as a both and the should be should be care such a thing think think think about that and having a project and I think about this and the update is and the original debut and the original and the lock chip and oxy Debian's use and the I and the now getting GitHub and the so communicate with them and the to update and the and the lock chip based original for that and they think about and now has and the check and the corner to assess that as made that sometimes so I and the and the have and the so a whole part chief to and the use and the you for the tip and the original and the Debian corner and operation system and you know almost in fine but windows windows windows and sometimes and even for and the microphone engineer now you think and you and the and the whole sometimes and the last being and the best it's both so hopefully and the now microphone best a hot in the windows and both and it is an official you know and other and the if and the iPhone is a jet phone and the and the and the plug in USB sometimes and the suddenly building so please check and the voltage and the ampere and the and the and the so the and the certified to use that and the and the at least and the checking and the and the and the jet phone and the it needs and the five volt four ampere and the say and they and they can also use and so five volt two ampere and you will see but it's almost and the things and the and the only and and the and the jet song and the you can you should use and the whole five volt four ampere s s adapters for that and and so late and the so latest and the so and the and the Raspberry Pi from Raspberry Pi engineers only about that and the so now ladies and the CPUs and the needs and the heat sink and the or spread this and the it is used to be a not so hot as a CPUs but it's an a 70 to the getting hold like species so you need to and the fun on the heat sink or using that and the so please be careful about us so and the and the and the and the issue and the and the you infrared in the channel and a bit these and the GP and the and the and so and the and the writing is a whole tip are using the and the I'm not using the high spec CPUs and or for the prevent the hot damage it. And some of the other PC vendors doesn't care about it, it gets under almost 100 degrees internal on the UMPC, it is useful. And so it is, and the USP issues, and the USP micro is supposed to provide 2.0 amperes. So it is not illegal to use on 2.5 amperes. So please be careful. And so using on the USP micro, that is supposed to provide 2 amperes, actually. Yes, and it is something like the latest case for that. And our own son, yesterday, presented this, and they're using on the Kubernetes or Raspberry per cluster. It is 100 Raspberry by 3s on the Kubernetes. And now in AI use. And it is on the Eden and AI startup in Japan, trying to Raspberry by using on the whole AI. And you have Json, and please be careful. And it is very hot. So I will show you briefly something use case for such a computer devices. And now, and it is for, it is, and Bonho, actually, they are Bonho, so a hobbyist, but is now using, it is using for the industry, lately. And getting a bit less on the, and keep using. So, and keep, education for the, and the programming. And it is for the signage. And it is for the audio use. And the streaming AI. And it is now helping, so the Japanese binary, and the helping of the business. And the solar power, the group height, and the checking, and the thermal, and the humus, and to use less agriculture chemical to hold grapes. So it is on the useful, and made on the natural, and the Japanese wine for that. And it is very simple use case. And using for something like business, and only such and the carside computers. And it is on the Taiwanese project, and so PM 2.5 measuring project, and in Taiwan. And it is, and also, and using for measuring PM 2.5 issue. And it is three efficient Taiwanese careers. Now they try to use that, measuring the PM 2.5. And it is for business, and the, and the, and the Japanese, and the, and the, and the university in the US. And it is, and made many systems. And so, you know, and the full-time distribution was. And so, it is for fibers. It is for database. It is for something, Lampstack or something. And it is a mini, mini, and infrastructure system to doing the business and the simulation in the, and in the university, using a Raspberry Pi. And the, that's all. Thank you. So any question for that? No? Any question? OK. Sorry? So you have to do the slides. I have more questions about this slides here. Could you give more details about the scenario? OK. OK. OK. OK. Thank you. Thank you for your question. His question is in the, in the more details. And the, sometimes I'll look. Sorry for that. And his question is on this, and the, and the agricultural, and agriculture use, or the, on the me called sideboard. And I will, and the, and the, take you in detail. And the, now, and the, and the Japanese, and the, Banyas, using on the, so Raspberry Pi, and the, so measuring, and the salmon, and the measuring, and the, and the humid, and the, to, to grow the grapes, for the Banyas, for the, and the, his wine, his wine. And it is on the, using also, and it is, and it runs on the solar batteries, and you can see. And the, growing by controlling, and the, and the AC, and DC control, and the Raspberry Pi, and the house, and the sin foods, and the, for the humid, and the, and the, and the, humid, and the salmon, and the, so sender, and the, and the, measuring the data, and the, and the salmon, and the humid, to send, and the, and the, so, and the website, and the graph it, and the, and the farmer check that, and the, okay. Farmer check that, and the, about that. So, and the, and the, he, and the, he checking in the, and the, every day, and so, and the, so he, and the, control, spreading, and the, and so, agriculture, chemical, chemical hold out. It is a useful, it is, it is safe, okay. If you want to try, and please, and them, you have to do it. Okay.
