 Okay, Lamar, what is this? This is my RP2040 tester for the RP2040 Feather. We finished this up and I want to show how the testing procedure works. I use a Tintzi and the USB host and this is really cool. I actually load the UF2 over mass storage onto here. This is my test jig, so I test all the pin connections. We just milled this on our other mill. I crank it down here and then press this button. It loads the UF2 file, does a serial test, and it finishes testing in two and a half seconds, which is awesome. Over here we've got the Eagle CAD file for the testing jig. You can see I test alternate pins that are not next to each other. And then this is the Pico SDK code that I load onto the Feather to do the GPIO test. This is in raw C, so it's really, really fast. So two and a half seconds is awesome. Yes, go test.
