Product Details

The MPR121 IC is a great way to build simple capacitive touch interfaces, and now it's even easier to incorporate into your Arduino projects with the touch shield. The touch shield has 9 capacitive touch pads, with headers for the remaining 3 electrode connections. With this shield you can have a total of 12 touch sensitive buttons. An on-board logic level converter allows it to work with 5V and 3.3V Arduino boards. Simply solder on some header pins and stack it on to your Arduino for a convenient input device. Check below for some example code to get you started.

We used 9 pads on our board as input,This board can be placed on the arduino board conveniently.

Programming Instructions:

This board use the 3.3v voltage of the arduino board,it communicate with the arduino board through I2C,the voltage of the MCU’s IO is 5V, in order to compatible with the Tocuth shield board voltage , the board used 2 MOS FET to solve the problems.

  • SDA------A4
  • SCK------A5
  • Interrupt------D2

Package Includes:

  • 1 x Touch Shield for Arduino

Notice: The interrupt handle function cannot work with the condition more than two key push down at the same time.
