Create a touch panel interface with the MPR121 Capacitive Touch Keyboard Module from PMD Way.

This board uses the MPR121 capacitive touch sensor controller driven by an I2C interface, and has twelve pads laid out in a keypad matrix on the board. 

Please note that this is a 3.3V board - which is great for Raspberry Pi or low-power Arduinos. Please use a level converter if connecting to 5V devices. 

The I2C address of the chip will be 0x5A. Inline header pins are included but not soldered to the board.

There is no regulation on the board, so the voltage supplied should be between 2.5 and 3.6VDC. 

Free delivery, worldwide.
