The Bare Conductive Touch Board is a printed circuit board module that can make your projects interactive, responsive, smart or just fun. Change the world around you by using the Touch Board to turn almost anything into a sensor.
Connect anything conductive to one of the 12 electrodes and trigger a sound via the onboard MP3 player, play a MIDI note or do anything else that you might do with an Arduino or Arduino-compatible device.
The Touch Board has been designed to be an easy-to-use platform for a huge range of projects, whether it is painting a lightswitch on your wall, making a paper piano or creating a customised interactive surface.
No programming required for basic operation
Arduino compatible and works with popular shields
Ideal for use with Bare Conductive paint or any other conductive material
MP3 Player / MIDI device
MicroSD card socket
Standard 3.5mm audio jack for headphones and speakers
Lithium Polymer (LiPo) battery recharges via USB
HID capable - turn the Touch Board into a keyboard or mouse
Board size: 84 x 62 x 10mm
