Pi Cap

$35.50 ex VAT


Connect your Pi to the physical world.

The Pi Cap adds precise capacitive touch, proximity sensing and high quality audio to your Raspberry Pi.

Connect your Pi project to the physical world. Create sensors by connecting Electric Paint or 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 A+, B+, Zero (or any Pi with  40 pin GPIO connector)
• Powerful C++, Python and Node.js libraries and examples

Works with:
Crocodile clips, copper tape,  solder and e­‐textiles. Use with Electric Paint to design your own sensors

 LEVEL: Beginner to Expert Engineer

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 Intro

The Pi Cap features tour walks you through the code examples that are supported by the Pi Cap library to give you an easy start to your project. Featured code examples include:

• 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
• Polyphonic 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.

Precautions of use:
Precautions of use: Children under 14 years of age must be supervised by an adult whilst using this product. This product is intended for use in conjunction with a Raspberry  Pi only. Do not use on conductive/metal surfaces as this may short circuit the board and damage it. Bare Conductive takes no responsibility for external circuitry connected to this board.

  1. Rated 5 out of 5

    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
