===== About =====
The Generic-USB module is a small microcontroller board for connecting applications to a computer using USB. It can be extended using application specific expansion card that uses one or more of the 15 available I/Os or use the I/Os directly for simple applications like temperature reading or TTL actuators. The module program memory can be updated over USB using a USB bootloader, see [[hardsoftware:genericbootloader]].
