 All right, lady. What is this? These are slim kale shock style switches These are very low-profile switches compared to most MX style Keycap and switches and we've got a little breakout that we designed for them This one has a neopixel that goes through It's got a socket so you can Connect either linear or clicky style. There's that glow through neopixel and then You need keycaps as well and then we've got a diode so you can matrix these and breakouts all over the place So you can breadboard these very easily so an update to our existing MX compatible Neo key as is the new key Chuck This is my new updated tester for our feather RP 2040 with RFM 9x Laura I did this board before and I had this module kind of like dangling off these pins here And I wanted to clean it up a little bit and one thing that added to our brains tester board is this I spy connector And this has SPI and I squared C and lots lots of GPIOs It's got way more pins than just these because it's a tightly packed Connector and then over here you see I have a Laura module and this antenna and this antenna or coaxial And so when I put this board down and I do the test The RP 2040 programs the client board the feather and then communicates with the Laura module Sending data back and forth that hello world and make sure that the signal strength is correct So this is a nice fast test for our new feather Laura boards All right, lady. What's this? This is me testing out our seesaw Neopixel driver, so this is a board that connects over I squared C and it has a AT tiny 816 here and then there's terminal blocks to connect it to neopixels So here I've got one wired up to this extremely long Well, there's a lot of pixels. It's not physically long But a lot of pixels like 200 pixels per meter LED strip and it's being controlled over I squared C Using Python 3 so we've got a circuit Python library and it's doing all these Neopixel animations and what's interesting is that yes, you know, this is a Raspberry Pi and we could We had neopixels directly from it But because this is I squared C this will work on any single board computer or device Even if it doesn't have a neopixel bit bang Timing support you can just send the commands over I squared C and it's converted to That's top secret of the week
