The chip can control up to twelve individual electrodes\nas well as a simulated thirteenth electrode. The MPR121 also has eight LED\ndriver pins. If these pins are not configured as electrodes, they can be used\nto drive LEDs. There are four jumpers at the bottom of the board, all of\nwhich are set (closed) by default. An address jumper binds the ADD pin to\nground, which means the default I2C address of the chip is 0x5A. If you need\nto change the address of the chip (by short-circuiting ADD to another pin),\nmake sure to open the jumper first. Jumpers also connect SDA, SCL and the\ninterrupt pin with 10k pull-up resistors. If you do not need the pull-up\nresistors, you can open the jumpers by cutting the conductor track that\nconnects them. There is no regulation on the board, so the input voltage\nshould be between 2.5 and 3.6 VDC. The VREG pin is connected to ground via a\n0.1uF capacitor, which means you cannot operate the MPR121 in low supply\nvoltage mode (1.71-2.75VDC) unless you modify the board. Features: 3? A\ncurrent in stop mode. 12 inputs with capacitance measurement 8 inputs are\nmultifunctional for LED driver and GPIO. Full touch detection. Automatic\nconfiguration for each sensor input. Automatic calibration for each sensor\ninput. Touch\/release threshold and debounce for touch detection. I2C\ninterface, with interrupt output. MPR121: 3mm x 3mm x 0.65mm Operating\ntemperature range from -40°C to +85°C.
