 All right, lady. What is this? Hey, I got my prototype for my TRS AT accessibility trinky This is a USB plug-in board with a SAMD 21E18. So it's a Cortex M0 that can run Arduino or circuit Python It's got a Neopixel and a TRRS jack. What that means is that it's a four pole eighth inch audio jack So you've got tip ring one ring two and sleeve and like this is a little breakout that makes it really easy for me to prototype and test with it and Accessibility switches at tend to use just tip and ring. They don't they're like a mono audio But you know, it's the same size as a TRS and the TRS you can connect multiple switches So, you know, even without a splitter just Wiring up these so that we have one button through this little like, you know plug-in play thing over here Goes to the tip and ring and then another button goes to the other ring and the sleeve And then I've got this plugged in here. It's got some demo code running and then I've got some circuit Python code that You know sets the non-used pens to be ground. Oh, sorry sets them to be ground And then it uses the keypad on the tip and the ring to and whenever it detects a pressed event It can write with HID. So if I open up notepad here and I press these buttons You'll see as I press them one button says hello and then, you know, the other button says a And so you can customize you can have it even have a do mouth stuff or like complicated, you know, multi-line Text inputs so it can be really good for easily customizable accessibility stuff. Here's the best part. No soldering is required It's like you can plug and play everything this plugs right in and then you can use terminal blocks with just a screwdriver to add Up to four switches So, oh no, it's mechanical
