 Sing it. New, new, new. New, new, new. New, new, new. New, new, new. New, new, new. New, new, new. Where's my cable? New, new, new. We'll edit this the best. All right. First up. Okay. So we have a revision, but it's a revision that I want to talk about because it's a big deal of vision. So the INA 219, which we revised to add STEM acute connectors. People love this. High or low side current sensor. And it goes over I squared C. It's one of our oldest products. I think it's like product number 904. So it's quite old. But here's the thing. So, yeah, sorry. Yeah. Click here. So, yeah. So we revised it and it looks a little different. And I want to explain what changed. So we could not get the INA 219B, which is the version of the SOP 23 chip that we've had for a really long time. So instead, what we did is we revised the board to use an SOIC sized chip. So the chip is bigger. And it's the INA 219A, not the 21... It may be the 219A, not just the 219B. The difference is the 219B I think is 0.5% precision and the 219A is 1% precision. The thing is, is that resistor is only like 1% precise anyways. So it's not like it's going to make a huge difference. But I do want to mention that the precision has changed slightly. We never promised that we'd have the 219B. We kind of just said it was the 219. We just couldn't get the 219B chips anymore. It was very difficult. We wanted to keep these in stock. And I think for most people's usage, the 219A is just fine. If this is absolutely killing you and you absolutely need the 219B. I think in the next few months, we might be able to revert back to using specifically the B subtype. But the next few months, basically we could only get the A type. And I thought it would be better to have it in stock, even if it's 0.2% less precise. Okay, next up. Okay. Next up, we have, you know, this is actually something handy for people who have a micro bit or you have a circuit playground express or circuit playground or any other, you know, project where it has like alligator clippy pads. So we had Tower Pro, which makes the servos that we really like, create a version of their micro servo, but this time it has alligator clips on it, which makes it really easy. Good for workshops. It's great for basically. Yeah. This is going to, if you've ever had to do any like step-by-step instructional learning, especially with youngins, you will appreciate this because you can get right to controlling a servo and not trying to figure out which way to plug it in. Yeah. Wrong stuff. Wrong wires. Wrong this. Okay. So it's going to be overhead. And I'll show off this demo. Okay. So basically this is a demo moving back and forth, but it's the same micro servo, geared plastic servo that you're used to. Send it one to two millisecond pulses and you can power it from ground and signal. And in this case, I'm powering it from V out, which happens to be five volts, but you can also power it from 3.3 volts. It won't move as fast or as strong, but I know the micro bit only has three volts available. But basically we have a servo to alligator clip adapter cable, which you can use with any servo, but if you just want to get started quickly with the micro servo, this is very compact and easy to use and the wires are color coded, which took us quite a few tries to get the right color coding, but power is red. Signal is white and ground is black. Yeah. This is going to save a lot of people a lot of time. Okay. I had the USB-C cable right here. It was plugged into one. Yeah. So it always is. I know. And also it takes like three times of plugging the cable to us. Yeah. I got it all. Okay. So we're continuing on our path to have our seven segment backpacks all come preassembled so that people don't even have to solder in the LED segment displays. So these are Stem and QT capable seven segment backpacks. So they're plug and play and you don't even have to solder in the LED segment. So let's go to the overhead because I'll show these off. Yeah. Do you want me to show both of them before we go to the overhead? Sure. Yeah. There's blue and white. We also already put in red and green. I think that was the last few weeks. Yeah. So we go to the page so you can select and get all the different colors. Correct. Here is the... Also one of our first products was the seven segment backpacks. It's great to be updating it. Okay. So beef one, two, three, four. So this is the two blue and white. They're incredibly bright. Matrix drivers and what's nice is of course now you don't have to solder anything at all. You can just plug and play over I squared C. You can have up to eight of them if you solder close these jumpers over here. But otherwise they're just stackable. You can put them next to each other. They stack up side by side. So you can have very long digits if you so wish. And always stem IQT. So we're trying to get everything to as little soldering as possible required to get started. Okay. Next up. Okay. Another update. So there's many updates because of the chip shortage which is causing a little bit of a back and forthness in the market. Oh, I was on the C-mail third. Oh yeah, these came in. Cool. These came in. It is like that. It's like, oh, these are finally... I can get these to you. Great. Okay. So this is the OpenMV M7. This is like a smart machine learning camera that you can program with micro pythons. Very powerful. It uses the STM32 H743, which if anybody knows is basically like total unobtainment. But they were able to get some stock to fabricate some. The only deal is they couldn't fabricate the version 2 with the... I think it's the MT9411 camera. So this has, I think, the OV56 something-something camera. It's basically version 1 for why we're selling version 2, but then chip shortage hit, crushed all hopes and dreams of getting STM32 H7. So the one thing we were able to get is to go back to V1. If you absolutely need V2, you really want that new MT9411 or whatever part number camera, please wait. Maybe in six months we'll have some of the V2s. But for most people's uses, it doesn't really matter. The camera quality is almost identical. The chip is the same. The software functionality is the same. So we have a couple hundred of these in stock. Honestly, I don't know when... And neither is open in Veno when they're going to be able to make more of these. Yeah, I figured I'd go on Chicago. So if you want one... Maybe a little bit. You may not want to wait out until the V2 is available. You might want to get the V1 and it's basically the same. Anyone has been waiting on ST chips. Yeah. If you're in an STM32 F7 or H7 world, you're... Yeah, you're in a world of pain. Okay. And no parts. Next up. And look, here's another STM based board. What a coincidence. So actually, this is funny. This one, they went to the GD32 F105, which is a giga device ST compatible chip. So this is the Blackmagic Probe. This is a really cool all-in-one debugger that has built-in debugging capabilities for a variety of chips, arm core chips. It's SWD programming. But what's really neat is it's kind of built into the chip itself. So you don't necessarily need to install open OCD. It's very popular. And we were out of stock for a very long time. They had to do a bit of a redesign for chip shortage reasons. But thankfully, we were able to get some of... They've also updated the firmware. It's now v2.3. So we got a bunch of these. And I think they'll be able to keep these in stock. Hopefully, giga device can supply them with the chips. And basically, this is kind of an advanced programming debugger for folks who are using... If you're using STMs or AMDs, any of the Cortex M0, M3, M4 processor, this will do the job. Check out the open source code also on GitHub. You can see the changes and also make sure that your chip is supported. All right. Next up. Okay. This is a very weird cable. So we didn't get a lot of these. What is this? Okay. So this is extra weird because we've actually stocked the... We've stocked USB-C PD cables already. And USB-C... What's interesting, it looks... I thought this was like makeup on it, but it's actually a translucent cable. Yeah. So these are very interesting cables in that you plug in the USB-C side into a wall adapter that can supply USB power delivery 5, 9, 12, 15, 20 volts. There's like power supplies that can supply different voltages based on what kind of cable device is plugged in. So we stock the cables that when you plug it in, they will give you like a fixed 9 volts out or a fixed 12 volts out. It's very handy because you no longer have to have multiple wall warts. Like you know how we have that box of wall warts at home? Yes. And like we can't get rid of it because it's always like you need it. No, there's always like I need that one. There's always something you need. So the idea is to replace those instead of having different wall warts with different voltages, the cable defines or the device defines the voltage. So we had the fixed cables and if you want like a fixed voltage, like I always want 9 volts or always want 12 volts, get that. Now, if you're freaky like me and you want a cable that can be reprogrammed to request different voltages, this is your thing. So this cable and this is so dangerous. It's like sometimes we carry stuff and I'm like you're going to hurt yourself. So try to like not hurt yourself. But this cable comes a little dongle. You see the dongle on the top right. You can program that there's some Windows software that comes with it and you can reprogram the power delivery requester chip to request different voltages. So you can have it be 5, 7, 9, 10, 12, 15, 18, and 20, I think. And you program it with these little kind of like, they're not EVADs but they kind of feel like EVADs are little code chunks. And then the cable turns into that cable. So one day you can have it be a 5 volt requester cable. The next day it's 12 volt. The next day it's 20. You can have it request the highest voltage up to you or the lowest voltage whatever. There's like different programs that you can program it with. Basically it's extremely dangerous because you don't know what you're going to, you know, like if you thought that you programmed it for 9 but it's actually 12. This is a super fun cable. Yeah, you could get 12. If you're interested in experimenting with power delivery, though I think it's, I think this does have some use cases, you know, especially if you're not sure what power delivery you want or you want to test a power supply with different voltages. So it's like kind of funky. I will say you do have to reprogram it between each settings. Like you can't, there's no button or anything to switch the setting. You have to reprogram it each time for the different settings. But it's one cable that can do them all. You know, just try not to hurt yourself with this. Don't forget what you set it to because you think it was set for 5 volts. It's actually set for 20. You plug it in and you blow up your electronics. So super fun. Okay. And Sarah said tonight besides you, lady, our team, our community, our staff, everyone who works with us, everyone who's supporting this adventure called Eight Fruit is the PCF 8575. Now you might be wondering well, why do you have a 16 IO expander? Don't you have the NCP 23 or 17? Yeah, we do. But we're not getting chips till 2024. So, or maybe, I mean, hopefully we'll get some sooner. But I wanted to have something out there for people who needed a 16 bit GPIO expander and did not want to wait for the MCP 23 or 17 expander to come back into stock. This is very inexpensive. It's very easy to use. It's a bit of a funky chip. We stock the F, F, sorry, P F, PCF 8574, which is the 8 bit version. And that's been in the store for a bit and people have liked that. The thing with that is, and this is they actually use very similar code. There's technically no direction register for the pins on this. There's only two modes for each IO. It's either a light pull up input or a strong syncing output. Basically, what this means is that if you want to wire up an LED, this cannot source current. It can only sync current. So you have to connect the LED from the power, one of the power rail pins to the GPIO. And if you want to have a button connected, you have to have the button connected to ground. So when you press the button, it shorts to ground. And that will use the light pull up on the input. It's not as powerful and amazing as something the MCP 23017. However, it's available and it's very inexpensive. And there's a lot of drivers out there. We wrote Arduino and CircuitPython slash Python code. There's three address pins so you can have eight of these. There is an interrupt output. There is an interrupt output pin. All light pull up inputs are automatically added to the IRQ. So it's a very simple chip, right? There's not a lot going on. There's like one iSquirtZ register, but it does work quite well. So I thought I'd show this demo, which is using the USB-C cable that I finally found. So I just have it, one thing that I liked about this breakout was that it was a little space so I added a power rail ground and power. Because again, LEDs, you have to connect the anode to power and the cathode to LED. You can't do it the other way. You can't connect it from the IO to ground. It will not be able to source current. It only gets sink current. And here's a button connected from one of the ground pins to an IO. And then I have a little Arduino sketch running on here. It switches which LED is lit back and forth, back and forth, all over GPIO and then just fell out. Second. There you go. Very simple demo, but it's effective. I mean, one thing that is nice about this is because the iSquirtZ interface is so simple, it's very fast. Like you don't have to read a bunch of registers and do bit masks or whatever. There's literally, you either write the 16-bit output or you read the 16-bit input. And that's it. Okay. And that is new products. Yay! New, new, new. New, new, new. New, new, new. I found my cable. New, new, new. New, new, new. All is good. New, new, new.
