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

Below are some project ideas to get you started!

Projection Mapping

Raspberry Pi projection mapping turns a simple graphic into an augmented reality interactive surface, activated by touch. You can find the step by step tutorial on projection mapping here.

DJ Mixer

The Pi Cap has polyphonic playback, which means you can play multiple tracks together at the same time, without needing to stop a playing track first. This allows you to mix songs and tracks and create your very own DJ mixer. Learn how to make your own.

Pi Cap Robot

The Pi Cap Robot can be navigated by simply touching the controller. The controller is created with Electric Paint and is then connected to the Pi Cap, which controls the motors of robot. This community project is by Clément Didier and you can see a tutorial on it here.

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.

    I had the Pi Cap for a while and it is something that I use for wireless projects and for some of my art projects. I use it with the Raspberry Pi 3 Model B+. If you’re using the Pi Cap, I would suggest learning some python so you can really take advantage of the hardware. There’s so much potential with this in the digital arts space.

    The on-board touch controller on these things is surprisingly accurate and the module/library support is easy to work with. I’ve been using it for proximity detection and it works really well for that too. Definitely a big thumbs up from me!

    PS: if you flip it upside down and connect some jumpers to the appropriate pins you can use it with any microcontroller that provides 3.3v power and I2C (not just Raspberry Pi).

    Got this in the mail today, hooked it up to try a few things, worked out great with my robot I run on letsrobot.tv. This paired with the electric paint I was able to make a border on the floor to give my robot bounds and deny access to rooms I dont want it in. I plan on adding more things, and am documenting the whole procedure here shortly. Great product!

      Great, send us some photos/videos we’d love to see
