Communication Protocol Description

• Communication Method: I2C (Inter-Integrated Circuit)
• I2C Pins:
  • SDA (Data Line): Pin D on the module
  • SCL (Clock Line): Pin C on the module
• I2C Address: The default I2C address is 0x16. You can modify the address via the dial-up switch on the module. The correspondence between the dial switch (A1, A0) and the I2C address is as follows:
  • A1=0, A0=0: 0x16 (ADDRESS_0)
  • A1=0, A0=1: 0x17 (ADDRESS_1)
  • A1=1, A0=0: 0x18 (ADDRESS_2)
  • A1=1, A0=1: 0x19 (ADDRESS_3)
