pinout

The 4 pin connector is connected as follows

1	Ground (G)
2	Rx (R)	do not drive at 5V level if jumper is set to 3.3v. probably works if driven at 3.3V with jumper at 5V.
3	Tx (T)	works at 5V or 3.3V level depening on jumper
4	V+	5V or 3.3V depending on jumper

• led1 is connected to CBUS0 (Tx activity)
• led2 is connected to CBUS1 (Rx activity)
• led3 is connected to VCC

Jumper settings

IO voltage
1-2: 3V3 (jumper near C2)
2-3: 5V (jumper near the edge of the board
