    What do you get if you cross the magic of the Touch Board with the might of the Raspberry Pi?

    A friendly add-on board (HAT) that adds touch sensing to your Pi projects. Designed with the Pi Zero in mind, its tiny footprint allows you to go small, portable and wireless. Want to add distance sensors to your robotics project? Need polyphonic playback for your music interface? The Pi Cap is your tool.


    The Pi Cap adds precise capacitive touch and distance sensing to your Raspberry Pi.

    Create sensors by connecting anything conductive to one of the Pi Cap’s 12 electrodes to control audio, video or connect to the internet.

    • Capacitive touch and distance sensing
    • High quality audio output
    • Tutorials to help you get started
    • User-­programmable RGB LED
    • Multi-function button
    • Prototyping area with GPIO breakout
    • Compatible with Raspberry Pi 1 Model A+ and B+, Pi 2 Model B, Pi 3 Model A+, B and B+,Pi 4 Model B*, Pi Zero and Zero W
    • Powerful C++, Python and Node.js libraries and examples

    The current Pi Cap version isn’t stable for Raspberry Pi 4’s Buster, but we’ll update it as soon as possible!


    The Pi Cap features tour is our special demo which walks you through the code examples in the Pi Cap library, giving you a super-easy start to your project. Check out:

    • simple-touch – Get data from the Pi Cap showing which electrode has been touched or released
    • datastream-tty – Similar to simple-touch, datastream-tty continuously streams the electrode data
    • datastream-osc – Similar to datastream-tty, but streams OSC packets to a specified host over a network
    • simple-touch-mp3 – This example plays mp3 tracks in the tracks folder when electrodes are touched
    • Text to Speech – Text files are synthesised (read out) by a computerised voice when you touch electrodes
    • button-utility – A single button press to prints Hello World! to the console, a double press reboots and a long press does a proper shutdown (avoiding corrupting your microSD card)
    • LED colour spinner – Display code status, debug or start a tiny rave. Example code loops through a variety of colours – the source code shows you how to manipulate the LED colour.
