      You can use the Foca or USBtoTLL moudle to connect your PC with this moudle.

      IIC Communication Protocol:

      The IIC communication, the module is equivalent to 24C04, EEPROM memory. And you can read the different address to get the information you need.

      Address Data
      0x00 -
      0x01 Angle value high 8bit
      0x02 Angle value low 8bit
      0x03 Magnetic declination high 8bit
      0x04 Magnetic declination low 8bit
      0x05 -
      0x06 -
      0x07 Calibration Level

      IIC command:

      Command Description
      0x00+0x31 Angle measurement
      0x00+0xC0 Start calibration
      0x00+0xC1 Stop calibration
      0x00+0xA0+0XAA+0XA5+0XC5 Restore default setting
      0x00+(0xA0+0XAA+0XA5+IIC_ADDR) Change IIC address of the module
      0x03+ 8bit Magnetic declination changes (high 8bit)
      0x04+ 8bit Magnetic declination changes (low 8bit)
      • Default IIC address is 0xE0.
