The I2C protocol use an address (0..127) to contact the target board with request and waiting for response. For sure each sensor boards must have an unique address on the I2C. On I2C implementation, the microcontroler do always keeps the control over the I2C communication. | The I2C protocol use an address (0..127) to contact the target board with request and waiting for response.
