Con_3 - In-Circuit Progamming Connector

The in-circuit programming connector, Con_3, is used to download new versions of firmware to the main CPU. This is a 10 pin header connector designed to be used for in- circuit programming with an ME Labs in-circuit programmer.

General Purpose I/O Connector

The GPIO connector provides 24 I/O signals that can be used for a variety of purposes. The signals inlcude 8 TTL level digital inputs with internal logic pullups, 8 open collector buffered outputs, 8 analog to digital converter inputs and ground.

All 24 I/O signals are protected from over voltage conditions using transient voltage suppression devices.
