9.14 Communications Connector - P12 (LCD Module)

The Communications Connector (P12) on the LCD module is intended for use with WiLink boards. All I/O operate at 1.8 V logic levels behind level shifters that limit some GPIO signal directions. The 3.6 V and 1.8 V rails are supplied by separate LDOs capable of 1.5A max each.
