Description

Turn touch into sound, light or data with the Touch Board from Bare Conductive. This micro-controller board benefits from 12 capacitive touch and proximity electrodes meaning you can turn any material or surface into a sensor and add touch and proximity sensing to your interactive projects. Pretty cool, right? Not only that, but Touch Board also features an MP3 decoder and MIDI synthesizer so you can use it as a USB mouse or keyboard, or even as a USB serial port or USB MIDI device. It’s based on the Arduino Leonardo and utilises the ATmega32U4, running at 16MHz and 5V. Need to reprogram it? It’s super easy, all you need is the Arduino IDE and a micro-USB cable. Touch Board also has a 3.5mm audio jack, microSD card holder, comes with a 128MB microSD card, a JST connector for an external LiPo battery, a power switch, and a reset button!

Key benefits of Bare Conductive Touch Board

It features 12 high-res capacitive electrodes – Touch Board utilises the MPR121 chip, giving it 12 capacitive electrodes to play with. You can configure these electrodes as either touch or proximity sensors and program them to trigger outputs or stream data.

Turn any surface into a sensor – not only is the base of the Touch Board completely level so it can be easily attached to any surface, but It’s also been designed to work seamlessly with Bare Conductive Electric Paint giving you the option to extend the Touch Board’s electrodes create sensors on a range of objects or substrates, from walls, floors, tabletops, textiles, or paper.

On-board MP3 decoder and MIDI synthesizer – Touch Board has got the VS1053b, which is an MP3 decoder and MIDI synthesizer in one. This means you can rock out to MP3 files or simulate a MIDI instrument. Plus, the MP3s are read off the microSD card that comes with Touch Board, and you can switch them up anytime you want, no need to mess with reprogramming the Touch Board.

USB serial, MIDI interface, mouse and keyboard – When you connect the Touch Board to a computer it can do some nifty stuff, like act as a USB serial, USB MIDI interface, or as a USB mouse or keyboard. You can take the data from the electrodes and feed them into software what utilises either serial, MIDI, or keyboard strokes.

FAQs

• What can Touch Board be used for? Touch Board is an easy-to-use capacitive sensing board that can be programmed via the Arduino IDE to create custom sensors. You can turn almost any material or surface into a touch or proximity sensor to trigger light, sound, or custom interactions. The Touch Board is the best tool to prototype and design capacitive sensors into your environment.
• How do I power the Touch Board? The Touch Board can be powered and programmed via a micro-USB connection. Additionally, it can also be powered from a 3.7V lithium polymer (LiPo) cell connected to the 2-way JST PH series connector.
• How many sensors does Touch Board have? The Touch Board has 12 electrodes for you to create sensors with. These connect to the MPR121 and provide capacitive touch / proximity sensing.
• How do I connect to the Touch Board’s electrodes? The best way to attach your sensor to the Touch Board is to connect a conductive material, for example Electric Paint, copper wire or crocodile clips, to any of its 12 electrodes. The Touch Board is the ideal tool to use alongside Electric Paint or Printed Sensors to create smart interactive surfaces.
• How do integrate Touch Board into my project? Touch Board’s flat surface mount design makes it easy to attach to any flat surface.
• How do I program the Touch Board? The Touch Board is like the Arduino Leonardo and can be programmed using the Arduino IDE and a micro-USB cable. It comes with plenty of examples to help you get started.
