 Welcome to the show, it's me, John Park, and it is time for JP's product pick of the week. And I wanna tell you, these are going like hotcakes today. We just released an allocation we had set aside for the show, and I can tell from the chat and also looking at the page itself that they are moving quick. So if you want to jump on this quick, head to that QR code or this URL right here, you can still watch this show from inside the product page, but they are going quick. So head on over there if you're here to tune into the show because we have a 50% off on this week's product pick, and it's a super cool one. Before I tell you about it, I'm gonna have Lady Aida jump back in time just a little bit to tell us about this week's product. Take it away, Lady Aida. The new ESP32 S2 Reverse TFT Feather. So this is a lot like our ESP32 TFT Feather, except you'll notice that it's, the TFT is on the back of the board, not the front of the board. So reverse. But this also means there's a little bit more space, right? Because I'm not sharing it with the USB and the whatever. And so on the back, you've got the ESP32 S2, you've got a stomach UT port. And on the front, we've got the TFT. It's a 240 by 135 pixel RGB TFT with IPS. So it's a very beautiful little display. You communicate with it over SPI. You've got the reset button and three IO buttons and the D0 button is also the boot loader button. So if you ever need to enter the boot loader manually, it's also available. So you got on the left USB-C, you've got another reset button, in case you need another reset button. I always like to keep it there. Battery charging. Oh, something new is I've updated these feathers. We used to use the LC709203 as a battery monitoring chip. We've moved to the max 17 048. Shouldn't really matter too much for you. It's just, it's a very nice ultra low-power battery monitor. Take a back care. I'm like, remember, there's a Neopixel on board. There's a second regulator. So you can turn off power in the Neopixel and the stomach UT port for ultra low power. We're using the RT9080 regulator on these boards, which means that the power goes down to like 30 or 40 microampures when in deep sleep mode. ESP32 S2 module. This mini module has four megabytes of flash, two megabytes of PSRAM. It's great for Arduino circuit, Python use, that PSRAM makes it excellent for IoT projects because you can buffer your gigantic JSON data. Like I mentioned, there's a max 17 048 battery monitor. It's ultra low power, but you just get really good battery monitoring on it. It'll tell you the percentage and voltage of your lipo battery when in use. You got these nice big buttons in these days. The new penguin font, so nice, legible sans serif font. Secondary regulator for the stomach UT ports who can have sensors and then depower them for ultra low power usage. This is the main regulator, battery recharging, JST, PH4 battery for portable projects, USB-C and then as we've mentioned, this beautiful front screen and three buttons. Let me see if the, okay. So this is the demo. So if I have I2C devices, the I2C 36, that's the built-in monitor, reset button and then the buttons D0, D1 and D2. What's that spot for a chip? Yeah, I think so. There is a chip. Is it a QT vertical? Yeah, there's a vertical stomach QT yet because there's no other way to have it, but this smells so good because it means anything comes out the back. This is for a BME 280, but we don't actually place it on there. It's just sort of a vestigial sensor. One thing just to note for the sensors is the D0 button when you press it, it shorts to ground. The D1 and D2 purposefully short to 3.3 volts. So the reason is as we learn this with the MAG tag, for the lowest power deep sleep interrupt wakeups, you want to have the power switch connect to power not ground. And this does a better job of allowing you to have multiple buttons trigger different wakeups. Like if you want to have multiple GPIO trigger wakeups. So that's why they're, if you're like, why is D1 and D2 different? That's why they are. And yeah, we'll also do an S3 version, but I wanted to get this into the shop to start. But I think this would be great for panel mounting or a case. Yes, the battery sticks out a little bit, but you can kind of fold this under and it's slim and you can still use feather wings. You just stack them on top of this way, right? It's stacked backwards. So if you want to add ethernet or whatever, go for it. All the TFT control signals don't go through the GPIO, just the SPI. So you have all these pins available. Yeah, that's right. We've got the product pick of the week this week right here. Let me jump to the down shooter there. You can see it in all of its glory, that beautiful, beautiful screen there. And I'm going to keep this one plugged in just because it looks so good. This is my product pick of the week this week. It is the ESP32S2 Reverse TFT Feather. Unfortunately, we have sold out already. I mean, fortunately or unfortunately, unfortunately if you wanted to get one, but fortunately because it means we've sold a bunch of these and they're out there in the world, which is good for everybody. But they are, I'm going to go ahead and unplug this one now. They are, I think, a really great revision to the existing ESP32S2 with TFT, which was on the top side of it. And that is largely because of how much easier it is to mount these into panels and enclosures. So first of all, let's talk about what this guy has got a little bit. So this is a recap from what Lady was saying. But the things I want to make sure that we mentioned, this is the 240 megahertz Tensilica processor on here. We've got four megs of flash. We've got two megs of PS RAM. This can do Wi-Fi, no Bluetooth, but this can do Wi-Fi, 2.4 gigahertz Wi-Fi. It has the native USB. It has a USB-C on it, which I love. It has a STEMI QT port for hooking up all your iSquad C devices. And you can see that that's actually one of the little vertical ports. Sometimes we use the horizontal ones. This is one of the vertical ones, which is, again, kind of nice if you're doing this sort of panel mounted to have that plug in from the top there. Still has all the usual battery charging. You can charge a lipo off of the circuit that's on there. This has these, let me jump to, let me jump back to the down view actually for a second to look at some of these great features on here. So you can see here we have, grab something to point with, we have these three user buttons here, and they're labeled D0, D1, and D2. D0 is also the boot button. So you can, if you need to do a boot select and reset to change the boot loader, you can use it for that. Otherwise, once the code is up and running, that can act as a regular user button. You just have to know that that one is gonna be the reverse of these other two as far as the pull direction, but you can use debouncer to fix that actually. It's one thing that is nice, so they'll all essentially say true when you press them or false when you press them, it flips the value. There's a reset button on the top. There's also a reset button on the bottom. So you have double the options there. And that's really convenient, again, because if you're mounting this in a panel, which I'll show you in a second, a little panel mount I made for one, it's really nice to have some user buttons here and the reset in case you need to, for whatever reason, you've frozen up the board or whatever, you need to reset it if you've maybe got a USB connection to it internally and you need to reset the board for that. It's all right there on the, what effectively becomes the top. It's really the bottom of the feather, but this effectively becomes the top or the front of the thing. Let's see, what else? So this is great for both Arduino and Circuit Python. This demo here, this is the one that it ships with. Let me start that up, let's flip this way. Oh, and here's the thing, I forgot to mention, of course, really obvious is the 1.14 inch 240 by 135 pixel IPS TFT display. It looks great from angles as well, being an IPS display, it doesn't just like disappear, you can get nice oblique angles there and still see it. This one right now is on this demo, giving us any, if you have a battery, I don't think I have one here to plug in, it'll give you battery monitoring that you can see on one line there. It'll tell you the I squared C address of anything plugged in and then also we have these buttons are responding. So when I press D zero, D one, D two, that's just letting us know that those are plugged in and being pressed. So let me show you, I think one of the nicest features of it is this panel mount option that you've got. So if you're mounting this in enclosures or if you're mounting this in panels, it works really well. I've got a little acrylic panel that I made, I just cut this, well, I designed it for this purpose to the specification of a EuroRack case, which is what I have it plugged into here. And you can see there's the four little mounting holes, just because of space constraints, by the way, we've got M two and M 2.5. I just used M two all the way around, but just know that these are really tiny holes down here just so they don't get in the way of the actual package, the chip package there. So I've mounted it into a little case that I made, I cut this out of acrylic on a laser cutter and it gives me a kind of a neat little way to very quickly add an ESP32S2 feather to a EuroRack project and mount it all in one. This program I have here running is just kind of a fake, it's just doing a little bit of dancing graphics. And then if I hold one of the user buttons, it flips the color of the bar that's above that one. So you can play around with it like that. I can get in a close up there and you can see how nice and sharp this screen is. Let me focus that. There we go, that's about as sharp as I can get it on this camera. But really nice looking screen. Again, like I said, it works well from angles. And if I pull this apart, you can see, I'll fix the focus yet again. I'll show you how this is mounted in here. So I'll go ahead and turn that off. You can see this is just running off of the case power since we've got a USB pin that'll accept five volt and one of the rails on a Eurorack power supply is five volts, that works well. Here you can see it's just sort of a temporary solution here and the jacks aren't connected up to anything. This is just sort of a proof of concept. But you can see there, it just mounts neatly and easily inside of the panel. You could of course plug in USB cable there, maybe make a solution to powering that and programming it from outside of the case if you wanted to. But the way I have this set up right now, just is sort of integrated into the power of the five volt that goes into the USB pin there. Close that back up. So let's see, let me see if we've got any questions over in the chat. There's our discord there. Let me switch this out here. If you're looking for the chat, by the way, if you're ever in Facebook, you can head on over to the adafru.it slash discord. I look for the live broadcast chat channel and also we've got the YouTube chat up. So let's see. Yeah, Keith Schluthauer asks, what's the width from pinhole to pinhole? Tackle the World says check the downloads page of the primary guide and that'll give you the specifications there. We have the production files available for download. You can go to the GitHub and grab all of those files if you need to. These are standardized on the feather. So for the most part, if you've come up with a design that'll work on one feather or work on most of them. Let's see. And yeah, and so by the way, so we sold out of those at the discounted price during the show. We will have more of these in stock. I think pretty soon there's not a huge constraint on that chip on ESP32 S2. So we're able to get them and make them, but the runs are typically in batches of a hundred. So that was I think one whole work order that got stashed and put up for the show. Let's see, other questions. DJ Devin three, some modules have really small mounting holes. Let's see, which one are you talking about? Yeah, this one is, I think these are M25 at the top and M2 at the bottom, just because of the size of the ESP32 package there. All right, so let's see what else I wanted to show. Here is if we head on over to the learn guide here. Oops, second, bring that up. There is a description of the board if you had to pin outs, you can see the nice job Katni did on doing both a front and reverse pin out, which is really, really, we really appreciate that Katni. Since this is the kind of board you may have flipped upside down a lot and still want to know what the pins are. She actually figured out a way to convert our semi-automated pin out diagram, pretty pins into a sort of mirrored version of it. So we have those up there. That's really nice, really helpful. And then this will tell you what all the different options are for powering, all the pins, TFD display, how that's connected through SPI, the Wi-Fi module, battery monitoring. There is not a BMA280. I think you can attach one if you want to. I'm not sure if that's going away on these. The pin out is there, the pads are there, but the chip is not on there. And there's a guide in here on how to set it up for Arduino, how to set it up for CircuitPython. There's also info on power management. And then again, going back to that question about the specifications on pins, if you head to the last page in the guide, this is true for most of the board guides and sensor guides. You will find the data sheets for chips that are on there. Here's the PCB file in Eagle CAD. There's a 3D model on GitHub and these. I actually really love these because the Ruiz brothers make these from the Eagle file, so they're accurate to the PCB. Usually put in step in a couple of other formats. Step is a really nice format for me using Rhino. So I can bring this in. When I made this panel, I just brought in that 3D model from the CAD file of GitHub. Duplicated some of the curves and chamfered them and filleted them a bit and duplicated the holes that were already in the 3D file for mounting and it all just worked out enough to double check the measurements or anything like that. Often I don't trust a 3D file out there in the wild. These I trust. I know they're built well and they're built from the CAD file. And yeah, and then you can also get the schematic. You can get the fritzing object if you're doing some work in fritzing with this as well as all of the different pretty pins, diagrams for this. You could print one out real big if you're using one of these boards a lot and wanted to have a reference next to you. All right, so let's see. I think that's probably gonna do it. Let me see if we've covered everything. Again, my apologies if you wanted to get one on the discount and they sold out really quickly today. These will be back in stock, not with the discount, but you can usually also find a 10% off during one of the shows. One of the live streams is usually a coupon you can get to at least get a little bit of savings on there. So let's see. I think that's gonna do it. Let me set this up for hanging on my pegboard there with a little wire hanger. That right there is my product pick of the week this week. It is the ESP32S2 Reverse TFT Feather. Thanks everybody for stopping by for Adafruit Industries. I'm John Park and this has been JP's product pick of the week. I will see you next time. Bye-bye.
