This is an expansion module for the IPC-SAM9G45 Linux System. It connects to the IPC-SAM9G45's four 2×10-pin headers to provide GPIO-controlled LEDs and serial interfaces — four 3-wire RS232 via DB9 (one for Debug), three RS485 via 3.81mm screw terminals, and one CAN bus via 3.81mm screw terminals.
