From the project
Augmentative and alternative communications device design files based on inexpensive and open source technologies.
These directories contain design files for two versions of an AAC controller based on the Atmel ATmega32U4. The designs are functionally identical but use microcrontrollers in different form factors. Version 1.2 is based on an ATmega32U4-AU (44-TQFP) while version 1.3 is based on an ATmega32U4-MU (44-VQFNA).
The most recent firmware for the controller can be found here: https://github.com/AbilitySpectrum/netCle/tree/master/Arduino/HubV2
