The chip can control up to twelve\nindividual electrodes, as well as a simulated thirteenth electrode. The MPR121\nalso features eight LED driving pins. When these pins are not configured as\nelectrodes, they may be used to drive LEDs. --There a four jumpers on the\nbottom of the board, all of which are set (closed) by default. An address\njumper ties the ADD pin to ground, meaning the default I2C address of the chip\nwill be 0x5A. If you need to change the address of the chip (by shorting ADD\nto a different pin), make sure you open the jumper first. Jumpers also connect\nSDA, SCL and the interrupt pin to 10k pull-up resistors. If you don't require\nthe pull-up resistors you can open the jumpers by cutting the trace connecting\nthem. --There is no regulation on the board, so the voltage supplied should be\nbetween 2.5 and 3.6VDC. The VREG pin is connected through a 0.1uF capacitor to\nground, which means, unless you modify the board, you can't operate the MPR121\nin low-supply voltage mode (1.71-2.75VDC). Features: 3 μA Stop mode current.\n12 capacitance sensing inputs. 8 inputs are multifunctional for LED driver and\nGPIO. Complete touch detection. Auto-configuration for each sensing input.\nAuto-calibration for each sensing input. Touch\/release threshold and debounce\nfor touch detection. I2C interface, with Interrupt output.
