The Touch Sensor Module provides an I2C interface through its 8-pin connector. The interface runs in fast mode, which means the speed is 400khz400kHz. With this interface, more advanced configuration could be performed. PIN 1, 3, 4, 5, 8 ( GND, DR, I2C_DATA, I2C_CLK, VBUS ) are used for this connection. It is recommended to use two 1kΩ pull-up resistors to tie up I2C_DATA and I2C_CLK pins to VBUS or 3.3V power supply to perform proper I2C communication. If USB connection is not used in parallel, PIN 6, 7 ( USB D-, USB D+ ) could be left unconnected.
