We are Tessel

Tessel is a completely open source and community-driven IoT and robotics development platform. Build fast with Node.js, then optimize the hardware and build thousands.

Tessel encompasses development boards, hardware module add-ons, and the software that runs on them.

One common misconception is that Tessel is a company. We're not! We're just a collection of (unpaid) people who find it worthwhile to spend our time building towards the Tessel Project mission.

What's a Tessel?

Our website should give you an overview of the hardware we build. You can see examples of things people have built on Tessel on our projects page.



This is possible thanks to all these people and organizations who contribute their time and/or money to support this collective. Contribute too!
