FWAA - a blast from the past

If you unscrew the head, you should see the driver revision printed on the inside next to the spring.

v1.1 has a SO-8 attiny85 that can be replaced with a QFN attiny1616 + small adapter, giving you 3 wire flashing and AUX capability. v2.2 has a QFN attiny85 that can not be replaced with anything useful easily, needs a USBASP or similar for updates and has too little IO for RGB AUX.

Both driver versions are crappy FET+1, however.
