Back

You can change I²C address by cutting A0, A1, A2 at the back of board and soldering pull-up resistor on surface.The address at the time of shipment is 7 bit, and will be written 1001 000.

Front

When you have cut the short jumper at the back to change I²C address, you will need to solder chip resistor (1608 type, 10 KΩ) to R4, R5, R6.

Corresponds to:
A0 → R4
A1 → R5
A2 → R6
