The MPR121 also features eight\nLED driving pins. When these pins are not configured as electrodes, they may\nbe used to drive LEDs. There a four jumpers on the bottom of the board, all of\nwhich are set (closed) by default. An address jumper ties the ADD pin to\nground, meaning the default I2C address of the chip will be 0x5A. If you need\nto change the address of the chip (by shorting ADD to a different pin), make\nsure you open the jumper first. Jumpers also connect SDA, SCL and the\ninterrupt pin to 10k pull-up resistors. If you don't require the pull-up\nresistors you can open the jumpers by cutting the trace connecting them. There\nis no regulation on the board, so the voltage supplied should be between 2.5\nand 3.6VDC. The VREG pin is connected through a 0.1uF capacitor to ground,\nwhich means, unless you modify the board, you can't operate the MPR121 in low-\nsupply voltage mode (1.71-2.75VDC). Features: Low power operation. 1.71 V to\n3.6 V supply operation. 29 μA supply current at 16 ms sampling interval\nperiod. 3 μA Stop mode current. 12 capacitance sensing inputs. 8 inputs are\nmultifunctional for LED driver and GPIO.
