Pi Cap

$34.90 ex VAT


Give your Raspberry Pi the power of 12 touch sensors

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. Make a MIDI piano, an interactive wall, a proximity sensor — you decide. Our Raspbian package contains code examples for C++, Python  and Node.js.

• 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 B and B+, Pi Zero and Zero W
• Powerful C++, Python and Node.js libraries and examples

Getting started with the Pi Cap

We have worked hard to make setting up your Pi Cap as straightforward as possible, whether you’re using a Pi Zero, Raspberry Pi 1 A+/B+, Raspberry Pi 2 or Raspberry Pi 3 our easy-to-follow instructions should help you get started.


In you’re wondering what the Pi Cap can do or what model Raspberry Pi you should use, we’ve created a series of resources which should answer your questions. If you want to know what the pins on the PCB are for, or whether you should use a Touch Board or Pi Cap in your project. Make sure to check out our Pi Cap guides.

Pi Cap Projects

The Pi Cap can be used for capacitive touch or distance sensing. Whether you want to keep it plugged in to a screen or make it a self-standing wearable, there’s loads of opportunities with this tiny and powerful add-on.


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.

    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!
