Hardware Notes

Serial Console

Serial console is on JP1. On my version of the ix2-200, JP1 is populated with a 4-pin connector at the backside of the board (see [[1]] for a picture).

Pinout:

Pin 1	VCC (3.3V)
Pin 2	TxD
Pin 3	GND
Pin 4	RxD

Pin 1 is marked with the label "JP1", it is the pin farthest from the battery.

Settings: 115200 baud, parity none, flow control xon/xoff, 8 data bits, 1 stop bit.
