SKU-5013, Bare Conductive Touch Board, Arduino Compatible Board

Bare Conductive Touch Board

The Bare conductive touch is a microcontroller board with a dedicated capacitive touch and MP3 decoder ICs. It has a headphone socket and micro SD card holder (for file storage), as well as, 12 capacitive touch electrodes. This device 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. This device resembles 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.
