MPR121 Capacitive Touch Sensor Controller Module - I2C Keyboard Thermoelectric Peltier Coller SMD components etcThis MPR121 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 are four jumpers on the bottom of the board, all of which are set (closed) by default. An address jumper ties the ADD pin to the ground,
