Tessel ARM Cortex-M3 MCU Board Brings Hardware Hacking to Web Developers with JavaScript and Node.js

People who are proficient with JavaScript or web technologies may not be completely comfortable with programming MCU in assembler and/or C programming language. Node.js, written in JavaScript, seems to be quite popular this days for diverse projects, but technical.io has decided to design a board called Tessel, powered by a Cortex M3 MCU. that can be fully programmed with JavaScript/Node.js.


Tessel hardware specifications:

  • MCU – NXP LPC1830 ARM Cortex-M3 @ 180mhz
  • System Memory – 32MB SDRAM
  • Storage – 32MB Flash
  • Connectivity – Wi-Fi via TI CC3000
  • Expansion – 16-pin GPIO bank for prototyping
  • Power – Micro USB or battery

The board is said to be compatible with 1000’s of Node.js modules from NPM, can be programmed via USB or Wi-Fi using your own IDE, and support Tessel modules, as well as Arduino Shields.

There are two (price) classes for Tessel modules:

  • Class A:
    • Relay — turn devices on and off (up to 5 amps)
    • Temperature/Humidity sensor — get information about the climate
    • Servo Driver – make up to 16 little motors move. Includes one servo. (Additional power supply included for US backers)
    • Accelerometer — get real-time movement data
    • MicroSD Storage — add extra storage to your Tessel (includes a 1GB microSD card)
  • Class B:
    • RFID (13.56MHz) — read RFID tags
    • Bluetooth Low Energy — send data to other devices, i.e. smartphones
    • GPS — get location information
    • Audio Output — decode and output sound files / raw audio

You can find hardware documentation, JavaScript libraries and sample code in the company’s github repo.

The company is looking for funds for mass production on Dragon Innovation, a new crowdfunding platform, and has already received over $100,000 in pledges. $99 will get your the Tessel board and a Class A modules, whereas $124 is good for the Tessel board and a Class B module.  Shipping is expected for February 2014. You can find further information and/or pledge on their campaign page.
