 Related to what is this. Oh, so we've been doing revisions for various boards and stuff But one of the other things I've been doing is revising the tester procedures. So historically for stuff like the feather ESP 8266 and ESP 32 feathers Because they have a USB serial converter I've had to use a Raspberry Pi computer to do the testing and so the Raspberry Pi would connect over USB and programming using ESP tool, but now that we have USB CDC support natively in teeny USB. I'm using a Pico through BitBang USB, which can actually do the programming for an ESP 866 or 32 via a USB CDC device, which is actually kind of cool There's like four layers of coding that needs to be done. But what's nice is that there's no Linux involved. It's super fast It's super compact No SD cards or anything So we're gonna be updating all of our testers to hopefully get all of them converted over to be Pico-ified as I put it
