Datasheet

To program the address offset, use a drop of solder to bridge the corresponding address jumper for each binary '1' in

the address.

Up to 4 boards may be connected. Addressing is as follows:

Board 0: Address = 0x40 Offset = binary 00000 (no jumpers required)

Board 1: Address = 0x41 Offset = binary 00001 (bridge A0 as in the photo above)

Board 2: Address = 0x44 Offset = binary 00100 (bridge A1)

Board 3: Address = 0x45 Offset = binary 00101 (bridge A0 & A1)
