Capacitive Touch Num Pad Shield 16-Key
It has the usual 16-key capacitive touch sensor layout plus 3 reserve electrodes on the corner of the board. It is based on the MPR121 chip similar to Adafruit's Numpad Shield. It can communicate via I2C, making it easy to interface to any controller including Arduino. There's also a built-in logic level controller on-board so it can work with either 3.3V or 5V logic. Moreover, there's a built-in LED indicator to show power status. You can solder it to your system with ease to add a Numpad to your project!
