This page contains the firmware and software resources for the USB I/O Controller IOaT-U4 product.

Firmware for IOaT-U4

The IOaT-U4 is powered up by the microcontroller ATMEGA32U4 from ATMEL. The electronic circuit is designed to be similar to the Arduino Leonardo (from Arduino) or SparkFun Fio V3 (from SparkFun). You can customise your own firmware using the open-source Arduino IDE software or Atmel Studio IDE.
