MPR121 Touch sensor module
MPR121 touch sensor is a capacitive touch sensor controller driven by an I2C interface. The chip can control up to twelve individual electrodes, as well as a simulated thirteenth electrode The MPR121 also features eight LED driving pins, when these pins are not configured as electrodes, they may be used to drive LEDs. There a four jumpers on the bottom of the board, all of which are set (closed) by default.
