a feathery toast to usb host! 🪶 🍞 you're probably saying "hey wait, the RP2040 doesn't have a secondary USB port! so what's that USB A port doing on this fancy new Feather? well, we do have a bit-banged 'full speed' USB host implementation available in TinyUSB. sure, it uses all the PIO slots and the second core but for some projects - say a datalogger that writes to a USB key, or an HID re-mapper - this board could do a fair job at it! we paired the RP2040 with a TPS61023 (adafruit.com/product/4654) an adorable 1A booster we've stocked for a while - it should easily be able to provide the 500mA / 1A peak that USB devices want.

@adafruit Does it use the PIO? Is it open source?
