Addressing the Shields

Each board in the chain must be assigned a unique address. This is done with the address jumpers on the upper right

edge of the board. The I2C base address for each board is 0x40. The binary address that you program with the

address jumpers is added to the base I2C address.

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

the address.
