MPR121 Capacitive Touch Sensor Breakout Board

Looking for a capacitive touch sensor controller driven by an I2C interface? It contains a chip that is capable of controlling individual electrodes that could reach up to 12. Also, the 13th electrode gets to be simulated.

These jumpers can connect different things such as the SDA, SCL, as well as the interrupt pin to 10k pull-up resistor.

Important things you should keep in mind include the following:
• Voltage supplied should be between 2.5 and 3.6VDC
• VREG pin is connected through a 0.1uF capacitor to ground, which means, unless you modify the board, you can't operate the MPR121 in low-supply voltage mode (1.71-2.75VDC).
