 This week's Iron MPI is Worth Electronics brought to you by Digi-Key and Ada Fridt. Thank you so much Digi-Key, Lady Ada. What is this week's newest, latest, greatest? From Worth. Yeah. It's high worth electronics. So I'm excited because we knew about these, but we can talk about them because of course they were secret. But Worth Electronics has come out with a series of feather wings. That's right. You know Ada Fridt because we've been making feathers. I actually looked it up. It was Maker Faire 2015 when we first showed off the first few feather designs that we came up with and feather wings. We had the feather 32U4s and the feather ESP866. And when we published feather, we made the spec open source. Basically, we published it and said, hey, anyone can use this. You can even use the word feather, feather wing, as long as you're compatible. Don't be a jerk and say it is when it isn't. And what's neat is that because it's been so platform agnostic, if you're going to get a nuclear board, it has to come from ST, and if you get an energy board, it's going to be an MSP430. But with feather, we support everybody from Maxim and NLog and Atmel and Microchip and TI and ST, and Nuvoton and Espressov and Nordic and everybody. And so it was cool to see Worth jump in and making these accessory feather wings because you know, Worth, I don't think they have in my controller family. And so this allows them to say, look, as long as you have something that's Arduino compatible and you have something that's feather compatible, you can use our feather wings. So there's a couple. So this is the sensor feather wing. Oh, and I wanted to just point out, sorry, this is the guide for Adafruit Feather. So check it out. We recently updated it because it lists a whole bunch of feathers as well as our awesome feather wing. It has a link to the awesome feather wing list, which is like a huge community of non-Adafruit made feathers. So the first feather wing, they made four. The first one is the sensor feather wing, which I also physically have here, and it's got pressure, humidity, accelerometer, temperature, and humidity. It's also got a quick STEMIQT counters on the bottom. It comes pre-soldered, ready to go, so you can just plug it into your favorite feather. It comes with all these sensors, and they all communicate over I squared C. So you can pop this onto literally any feather because all of them have I squared C connectivity to add a huge range of sensors from Worth. They also publish schematic in the data sheet, which is really handy, which has all the part numbers. And there's also the board files as well, though I didn't download them, but basically they publish everything. They're like, look, we want you to use this as an eval board, and this is a working schematic that you can use. The next board, I thought this was interesting, is this is, sorry, can you enlarge it? I want to remember how to spell it. It's the thion, thion. This is a 2.4 gigahertz mesh network chip, so it's that little module at the end there. And this is what you would use if you don't necessarily want to have, you want to have a low power mesh network, Wi-Fi isn't mesh. If you want to have a sensor node, maybe all these sensors using that sensor feather wing, and then you want to distribute data around a mesh network, this is a meshing module that makes it really easy to use, also comes in a feather wing format. And you communicate with the radio module over UART. So all of our feathers also have UART. And then there's an ATE-ECC-608, which is a common encryption, you know, private key storage device from at-mail microchip, and that communicates over I-squared C, and there's Arduino libraries for that. So between the two of these, you can basically have authenticated mesh networks that have unique identifiers. Also the schematics are published for this, and this is basically designed to be a dev board to demonstrate the thion mesh module. The next module, I thought this was kind of cool. So this is like this, it's called like a magic power feather wing. And this uses, worth electronics makes a lot of power modules. This is a step-down module. So you can see all those capacitors and connectors and inductor in there. And this basically will take up to, I think, 24 volts input and do a buck conversion, bring it down to five volts and also three volts. So basically if you're using your feather or feather wing in an industrial environment, like let's say one of those low-voltage trains we were just talking about, that went on 32 volts, you could wire this up and basically have a train sensor module. And you won't have to worry about power supply, and it can power the rest of the feather in the mesh network, what have you. Of course you can also use a LiPo battery, as all feathers do. But if you want to, you know, we don't currently have a feather wing that will let you take 24 volts and bring it down to five, so this is quite handy to do so. Also the schematic is here, but you can see it's basically a power module with an alternate power input. And then lastly there is a Calypso Wi-Fi feather wing. So this is a Wi-Fi module that you can use to connect to the internet securely. It uses UART and there's an Arduino library, so it has AT-style command structure which is really common. And they have Arduino libraries for it if you'd like, so this uses UART, so you can't really use this and the mesh wing at the same time, so kind of use one or the other, unless you have two UARTs and you can rewire it. For the most part you just kind of pick one or the other. And this is basically how it connects. Basically just over UART you send AT commands to connect, you know, make a socket, connect, send data, open and close it. You can also act as a web browser. And then of course here's the documentation for how it's wired up and put together so you can use the Calypso module. And then there is a video, we didn't show the video because it's like 15 minutes long, but there is a video on the Worth YouTube channel to check out where they take a M0 feather and they plug it into the Wi-Fi and the sensor feather wing and they basically make a fully interactive post and get web service, web browser. So the web services on the feather M0 connects to Wi-Fi securely with the Calypso Wi-Fi weather wing and then you can read the sensors and set the LEDs so it's read and write with a custom Wi-Fi interface. And if you want to use this again because Worth doesn't make the microcontroller board, you would use a feather M0, a feather M4, you know, an NRF-D2840, maybe on a Bluetooth, and then check out their GitHub repo where they have code for the sensor, Wi-Fi and mesh feather wing, that example code for all of them. And they're in platform IO specified format, but they should work just fine in Arduino as well. You just have to drag and drop that into your library folder. They are in stock, all four of them, four different types, and I can show it on the overhead real fast. So, boom. My Sharpie. So this is the sensor feather wing. So on the bottom, it's got all this documentation. Focus in on it. The humidity sensor has a nice cutout for temperature and humidity so that there's no self-heating. They come with stacking headers, which is great because you can take, you know, your feather and pop it on top, especially if you have like a Wi-Fi feather. You won't have anything in the way of the antenna. Or, you know, you can have socket headers and this plungs on top. And then there's a quick connector here. So if you've got your, you know, some other sensor you want to connect or maybe encryption module, whatever, over iSquad C, you just plug it in and you can extend that. Or, of course, you can use this to just connect to an existing like a QDPI board if you just want to use this as a sensor module breakout. So that's the worth sensor feather wing. There is a part number, but by the way, it's extremely long. I can't remember it. So just type in worth feather wing and you'll find all them.
