AA Boards and Tools

This repository contains some schematics and board designs that have been useful when trying to understand the communications used by the AA system.

• An interceptor board that sits between the tablet and CB and allows the RS485 lines to be read.
• A 'hat' for a Raspberry Pi that uses the 14v supply to power the Pi, and provides circuitry to allow the PI's built-in serial port to communicate with the RS485 data bus.

As always, YMMV. Verify designs before using them. Don't mess with stuff you can't afford to break.
