Because we use the UART, this works with all Feathers except for those with

USB-Serial converters that use the UART pins. Right now that means the

ESP8266 Huzzah Feather, 328p Feather and nRF52 Feather don't work because

they use the hardware UART for programming. Any other Feathers with native

USB will work just fine.

Comes as a kit with an assembled PCB that has all the surface-mount

components attached, loose headers, and two loose DIN-5 jacks. Some basic

soldering is required to assemble the header and DIN jacks in place. If you're

like to use 3.5mm jacks, you'll want to pick up some through-hole 3.5mm

stereo jacks and solder those in, instead.
