 And welcome to Lady Aida. Raspberry Pi edition. You know it's time to wear the Raspberry Pi shirt that has the green leaves Which means it's it's two in the morning to the morning and that means there's a Raspberry Pi. I know release somewhere So let's just get let's just get right to it. There's a new Raspberry Pi new Raspberry Pi and Lady Aida This is the Raspberry Pi Let's do this to Wate it's the Raspberry Pi zero to W. Yeah There's a lot of letters. Okay, so it's a Raspberry Pi. Okay, so it's a single board computer So, you know that and it's a zero which means it's the you know the skinny sized board They started with the Raspberry Pi zero then they had the Raspberry Pi zero W and now there's a Raspberry Pi two Zero W or zero to W. I don't remember which way it is basically it's the second generation and It's a little ironic that it's the two because it's actually got the same chip as the Pi three. It's a quad core Chip so, you know, it's like it sounds like it's the pi two, but it's actually pi three speeds It's like five times faster And it's got 512 megabytes of RAM But it's the same size and it's got all the same connectors as the Raspberry Pi zero So here it is and it's also got a nice tin over the Wi-Fi and Bluetooth stuff It's actually interesting. I've been did an interview that we read. I think it was on make and He mentioned, you know a lot of like they really don't sell that many Pi zero Non-W's anymore pretty much everybody if you're gonna get a Raspberry Pi You're gonna spend a little couple extra bucks to get W the Bluetooth and Wi-Fi add-on which makes sense Like that's it's cool where it's like you can have wireless connectivity. Otherwise, it's kind of hard to You know, it's a little bit more work to connect and use the device And so not surprisingly they kind of skipped over the non-W Style for the zero went straight for the W. So it's got the quad core Raspberry Pi three Broadcom chip with the built-in 512 megabytes of RAM. It's got the micro SD slot for, you know operating system and flash One HDMI output ports, then you can do 4k There's two Micro USB connectors one is for power and this board does use a little bit more power than the original Pi zero also Thankfully Gareth did all the You know benchmarking and power measurements because I was like I was gonna do it, but like I'd rather have the official numbers the other Port on the Raspberry Pi zero is for USB gadget It can be used either as a USB peripheral where it acts like a USB device or you can use it a little USB host adapter dongle that converts it to like a USB a Port and they can plug in you an Ethernet or a hub or a keyboard and mouse or you know What have you we actually have a bunch of accessories some of which even have the micro USB connector already on it At the end there's a little camera connector You can use that to connect to the Raspberry Pi CSI cameras with the cable adapter We have a couple in the store and of course it's got the 2 by 20 standard GPIO and the same pinout configuration That you expect with SPI and I squared C and PWM I think you know, there's probably going to be a little bit of time until Some things like maybe the neopixel library support for this needs to be adapted to recognize in this new Configuration and then we'll have blink of support in a couple days as well But basically it's like a pie zero, but it's like five times faster Which is which is really the one thing that the pie zero, you know was a bit of a struggle with it was It was the the same speed as the original Raspberry Pi which made it You know a little tough if you wanted to do like web browsing or or you know use it with scratch or Play videos now you have this little teeny board and it's and it's fast enough to like you know be a computer You can actually do a computation. You can definitely run emulators on it and they won't be slow And it's a great little upgrade You can just slot it wherever you use the Raspberry Pi zero and it's five times faster So I can go to the computer and I can go through some Yeah, and we'll have a bunch of photos and more on our website and then also the products live so what you do is just sign up and We do something different than you know, I think a lot of folks Will notify you the seconds in stock and that's when you purchase So it's yeah It doesn't make sense to place the order now because there's a lot of things that may or may not show up immediately That's the best way to do it. Yes, so it's not unusual America usually gets the boards a couple days after The UK the UK gets the boards first of course because that's you know, that's where Raspberry Pi lives And then they have to pass they have to publish the FCC certification and then they can import the board So we usually get them like in two or three days And we do notify people in order when they signed up. So there'll be a limit one per customer But if you sign up, I will say because of the silicon shortage If you don't get it from the first batch, you know, I'd love to say like don't worry. You'll get it later It might be a couple months Just I want people to be really understanding that we're living through a global semiconductor and shipping shortage and It affects everything including Raspberry Pi's I know people have noticed that it's been tough to get Raspberry Pi 4s and Raspberry Pi zeros We do have a batch that's been ordered They're booked they will arrive here in a couple days or you know a week or so After that, it might take a couple months to get more So I just want people to be super chill and understanding. The fastest you'll get them is my opinion since we do this is Sign up. Just sign up when you get the email. Yeah, and like we're pretty good about letting folks know, okay They're gonna go in and Yeah, we'll have a limit you know so many per customer because folks like to Very small number of people like you read it for others They'll buy them all out and try to get them put them on eBay or yeah, we don't we don't allow that. Okay, so This is From Gareth he he did a nice You know specs demonstration again, you know, it's the chipset is The BCM 2837 same as the Raspberry Pi 3. It's a quad core Cortex 1 gigahertz Cortex a 53 You know when question people are probably gonna ask is doing a heat sink and the answer is like you don't need a heat sink because You know, even though it's a quad core. It will internally throttle the speed a little bit You know pi 3s pi 4 is definitely, you know Benefit from a heat sink. Hi 3s. I never felt like they needed one I don't think you need a fan But one of our little aluminum heat sinks on the chip, you know, probably get you like maybe 5% more Speed at if you're if you're pushing all quad cores Computationally all at the same time. It's not going to affect, you know, just everyday usage But if you're like playing, you know YouTube videos consistently or you're doing like a lot of emulation or anything. That's like very computationally intense It uses all four cores that heatsink could help. Okay So here is the benchmarks for power draw. So this is the new Pi zero two is over here So you can see the idle power is about the same which is not was not too surprising There's not more peripherals on The pi zero two. I there's no, you know, ethernet chipset. There's no USB hub The Wi-Fi and Bluetooth, you know, unless you're Transferring data, they're not going to draw any power So the idle I mean the idle power, you know, not not too surprisingly Is about the same when you actually start, you know Loading it down running software. The power draw is going to be about twice as much. It's going to be about Looks like three ish watts or so Instead of, you know, 1.8 watts, it's about twice as much So three watts, you know, and usually running about five volts So we're talking, you know, you know 800 milliamps or so. So you can definitely, you know, if you have peripherals You can run it on a, you know, if you have a couple small peripherals You can run it on a one amp power supply five volt If you, you know, are attaching like HDMI screens and you want to power them from the same USB port and whatever Yeah, you get a two amp power supply. We sell the two amp power supplies and they're plenty for this So there's definitely more power draw. This is, you know As you went using the cores, important if you're making portable stuff I know people like the Pi Zero's for portable stuff because the power draw is quite low So, you know, it will matter if you start loading it Thermal, you know, it looks like there is thermal throttling Let's see, extra packs of heat So drop the clock speed of the CPU cores to one gigahertz. Okay, so basically I think the original Pi 3 was running at 1.3 gigahertz. It looks like they dropped the power to the speed to one gigahertz You can pop over clock it and that's when you'll probably want to have a fan or heat sink But again, it's like once you start doing that, you know, you're you're kind of voiding the warranty You're doing not what you're, uh, what the engineers recommend And this is a, uh, a thermal camera. We like thermal cameras, thermal camera image Showing, yeah, all the power is definitely you can even see the, you know The computational area or the RAM area of this chip It gets quite hot The CPU is nice and flat again, you know, you want a little heat sink, put a little heat sink on there And you'll you'll definitely be able to dissipate it out and um Okay memory bandwidth, so you're going to get way better And you're seeing like, you know, the quad core chips, especially the a 53 You're gonna see similar bandwidth support like you've got this quad core And it's a, you know, much better chipset and your family. So you're definitely going to be able to push more data around So that's good Storage benchmark, it's about the same not surprising. Um, your your sd throughput is really going to be Based on the sdio controller the mmc controller and it's pretty much the same on all of these chipsets I'm kind of surprised that the pi 4 goes surprisingly faster. It could be like Better caching. I don't know. That's pretty cool. Um USB storage, um, I think, you know, which scott was talking about how on the pi 4 Or maybe the pi 400 is saying that the usb actually goes to pcie Um Or something and so that's why you were able to get like, you know, usb 3 speeds Folks remember the pi 4, you know, you have the usb The the higher speed usb ports The pi zero has, you know, that one usb port and it's it's kind of the same speed as the pi 3 Maybe not so great for, you know, 100 gigabit ethernet adapters, but for most use cases, it's going to be just fine um For lin pack, that's a benchmark. Um, you know, you're going to see close to pi 2 Sorry, pi 3 Benchmarks so it's not too surprising. So yeah, you know faster than the the pi zero Uh, gpi is zero. It's interesting. I wonder why it's not Faster. Oh, it's probably because of the cpu speed. So the pi zero two, you know, almost as fast as the pi 3 Um, I'm guessing all the times it's not as fast as the pi 3 for something is it's because it's the 1 gigahertz not 1.3 gigahertz or 1.4 gigahertz speed um Compression, you know, anything that has to do with with computation Um, the pi zero two is going to do, you know, quite well. So you see it's about Half the speed twice as fast Image editing also, you know, looks like about twice as fast um Gaming, I mean looks like open arena doesn't even run on the pi zero and then on the Zero two it runs, you know About 80% as fast as a pi four And you know similar again, like, you know, there looks like he did like hundreds of little benchmarks But basically the pi zero is the pi zero two you're going to get like pi three speeds, which will be about 60 50 60 70 percent of the speed of a pi four, but uh very small on 15 dollars. So Um a big upgrade. I think a lot of people who've made like little portable devices are going to really like this If you want to, you know, if you're just making a little You know pi whole blocker, maybe it's not going to matter, but if you want to like actually Store something or display something or compute something. Um, it's definitely a good upgrade So I think you're not, you know, you're going to basically see people Aren't going to get the pi zero w anymore for the same price just upgrade for the 2 w Five times faster tons of ram Same shape You know, why not? And for our world and all the things that we do um Scott's getting circuit python to do a lot of interesting things on raspberry pies And so tune in on scott's deep dive this friday Well, by the way, we'll save you one out scott as soon as I figure out how many we have total Um Here I have like one. Yeah, I have this one. I think we have this. Oh, yeah. Do you want to show them the overhead? Yeah, it's like it's real it's here, um Yeah, and uh I think it's going to be really need to have like a very small powerful Computer that you can make like it's yeah, I think this is it's cute. It's pretty amazing where we're at with uh I think it's interesting that you know, there's this five dollar computer But people are willing to spend 10 bucks more to get wireless. I think that it shows value Anyways, people have questions. I mean, I'm not that hardware engineer for raspberry pie, but I can I can bullshit my way through some Well, I think some people are wondering if it has like significant speed increases because you know, they want to use Yeah, it's it's about five times faster. I mean, it's not going to be as fast as the pi four But from all the benchmarks, it looks like it's about, you know 60 70 percent the speed. Yeah, there was a there's an interview on make magazine magazine They accidentally let it live last night and I happened to read it. It's an interview with Evan They talk about like how they're becoming a pc company all that stuff as soon as it's back online um Make probably um, isn't up right now um, but when they when they release the article Yeah Check out like where they're going. It's a it's a really interesting. Yeah answers our article. I'll uh, I'll do a post um When I take a nap and get up and see see all the coverage and I'll do a roundup or something The good news is all the accessories that you have for the pie zero the cameras and the cases They're all gonna work. You know, um, it still comes without headers soldered in but it's inexpensive um I think it'll be you know, I think it's fun. I think definitely, you know, I know people I've really seen people make like cute little emulator type things With pie zeros. So this will this is definitely going to be a nice little boost I think you can actually start running games or or using it as a little mini computer I mean the pie zero was good, but it was really it had that single board Linux computer feel of like just like oh like I'm running stuff, but like it's kind of Challenging it feels like the 90s Whereas this it's like, oh, yeah, you can like decode mp3s and like, you know download stuff on the internet And and it's it's nice and in perky. It feels it feels fast All right. So that's it. Um, we're gonna Take a nap and we're gonna be right back at it. Yeah And thank you everyone for tuning in. This has been a special edition of uh, disc of lady aida Special uh I only wear this shirt for these specials special raspberry pi zero two w edition It's gonna go back in the closet. All right. Thanks everybody. Good night. Okay
