Tessel is open source.

The Tessel Project is under open governance. Keep up with us on our blog and talk to us on the forums.

Tessel and modules are open source software (OSS) and open source hardware (OSHW).

*NOTE: many components on the board lack proper 3D models (we used the closest thing we could find), so don't trust them to more than ~0.5mm. Board dimensions and holes are correct, though.
