Augmentative and alternative communications device design files based on inexpensive and open source technologies.

These directories contain design files for a lightbox display peripheral, for use with an i2c (green) controller input.

The lightbox is based on a Microchip MCP23008 8-Bit I/O Expander: Datasheet
