Straight out of the box, the Touch Board enables you to turn any conductive object into a sensor, which can be used to trigger a sound. The board has 12 of these capacitive electrodes and it can be reprogrammed to either make use of the on-board MP3 decoder and MIDI synthesizer or to be used as a USB Serial, MIDI interface and mouse and keyboard.

The Touch Board is a microcontroller board based on the Arduino Leonardo, using the ATmega32U4, and includes a 3.5mm audio jack. Sounds can be stored on the board via a microSD card and you can reprogram the Touch Board using the Arduino IDE and a micro USB cable.

Touch Board product description :

The Touch Board is a microcontroller board with dedicated capacitive touch and MP3 decoder ICs. It has a headphone socket and micro SD card holder (for file storage), as well as having 12 capacitive touch electrodes. It is based around the ATmega32U4 and runs at 16MHz from 5V. It has a micro USB connector, a JST connector for an external lithium polymer (LiPo) cell, a power switch and a reset button.

It is similar to the Arduino Leonardo board and can be programmed using the Arduino IDE. The ATmega32U4 can appear to a connected computer as a mouse or a keyboard, (HID) serial port (CDC) or USB MIDI device.

  • Microchip ATmega32U4 microcontroller
  • Audio output 15mW into 32Ω via 3.5mm stereo socket
  • Up to 32GB removable storage via micro SD card
  • 5V DC operating voltage
  • 400mA max. output current, 100mA at startup(5V rail)
  • 12 Capacitive touch electrodes, eight configurable as digital I/O
  • 12 Digital I/O Pins with five additional pins available via modification
  • 7 PWM channels (shared with digital I/O pins)
  • 12 Analogue input channels (shared with digital I/O pins)

Touch board by bare conductive graphic


The Touch Board has 12 capacitive electrodes that respond to a touch. These electrodes can be extended with conductive materials, like Electric Paint,


The Touch Board has on-board MP3 playback and a MIDI synthesizer. This means you can either play MP3 files or simulate a MIDI instrument by touching the electrodes.


In order to hear the sounds coming from the Touch Board simply connect either headphones or speakers to the 3.5mm audio socket.


Upload MP3 files onto the supplied microSD card and change it without having to reprogram the Touch Board.


When plugged into a computer, the Touch Board can act as a USB serial device, USB MIDI interface or as a USB mouse or keyboard. Use the data from the electrodes as an input for software that utilises either serial, MIDI or keyboard strokes.
