Description: The Tessel 2 is a development board with on-board WiFi capabilities that allows you to build scripts in Node.js. This Tessel provides you with a connected hardware prototyping system that can be used in multiple different applications. Each board boasts thorough command line tools that make it simple to deploy your code, set WiFi credentials, and easily manage authentication needs. With the Tessel 2 you will be able to interact with the physical world from sensing to actuation to connecting with other devices. It should also be noted that though the Tessel 2 is programmable in JavaScript it does possess the ability to support other languages as well!

The Tessel 2 is equipped with a slew of on-board features including two 10-pin module ports to add sensors and other external hardware, two USB ports for camera peripherals and flash storage, a 10/100 supported ethernet port, and a microUSB connector for power and tethered programming. Each Tessel 2 offers an 802.11 b/g/n WiFi setup, a 580MHz Mediatek router-on-a-chip, a 48MHz SAMD21 coprocessor, and 64MB of DDR2 RAM with 32MB of flash.

Needless to say, the Tessel 2 has been designed from the ground up with the fastest possible path to producing your projects. Simply plug and play multiple modules and high-level APIs and you have a development board that is levels ahead of most other development boards!

Customer Comments

  • Is it possible to power this with a battery? How is the low power options exposed?

  • How customizable is the embedded node.js system? Can I upgrade it? Can I use npm to install global packages? Are there limitations? Most importantly, is this running some sort of embedded Linux?

    • Yes, yes, and OpenWRT. Tessel 2 is very picky when it comes to what version of Node.js you run on a host dev machine, 4.2.x is the ticket currently, but any OS can be used. Support on Windows 7, 10 until recently was a little sketchy, but it’s working pretty well now. Using the T2 from a Linux environment such as a RPi actually works quite well. On any OS, you are able to deploy code via USB, WiFi or LAN, which is pretty nice. I was a supporter of T2 on Kickstarter and have many hours of “fun” under my belt now, but as I said, things are pretty stable and working as intended at this point.

  • The datasheet for the Mediatek MT7620 says this SoC has five ethernet adapters. Are these broken out to the female header, or … ?
