     This Capacitive Touch Shield has 9 build-on capacitive touchpads, and the other 3 electrodes for further usage. With this shield, you can have a total of 12 touch-sensitive buttons. This Shield uses the MPR121 which is a great way to build simple capacitive touch interfaces using the I2C communication, and now it’s even easier to incorporate into your Arduino projects with the touch shield. An on-board logic level converter allows it to work with 5V and 3.3V Arduino boards and a LED to show you the power status. Compares to another touch shield that using digital pins, this shield uses fewer pins, which allows more pins left for other usages.
     All the header pins are not soldered, so you can solder them by yourself to use it as Arduino “Shield”, or just solder the necessary pins(Power/GND/I2C/IRQ) to make this board more easy to implement anywhere.
