Pi Cap for Raspberry Pi: your PI in HID mode

The Pi Cap is a shield that’s fully compatible with the good old Raspberry Pi, bringing it all the new capabilities from the Bare Conductive universe. Now your Raspberry Pi offers virtually the same functionality as a Touch Board.

You can create all the projects you’ve dreamed of, even the craziest. Any object around you can be turned into a MIDI piano key, or a sensor; and with a bit of electric paint and a few accessories (e-textiles, alligator clips, copper tape, etc.), your whole house can become interactive.

Bare Conductive Pi Cap: a custom software environment

Bare Conductive had developed a complete code library to help you program your next projects using your Raspberry Pi. Whether you’re a fan of C++, Python or Node.js, no project will be beyond your range. Visit the Bare Conductive website to make friends with a very active community of creators, always ready to share their good ideas!
