DIP vs IIC Address

The IIC to dual UART module is a non-standard IIC device with various addresses. IIC address has 7 bits. When running the IIC scanning

program, as long as the upper 4 bits are the same as that of the module, and there will be reponse. So you can scan multiple IIC addresses

with same upper 4 bits on one module.

The 6th bit: IA1 corresponds with the value of DIP switch Al on the module.

The 5th bit: IA0 corresponds with the value of DIP switch A0 on the module.
