AN OPEN HARDWARE COLLECTIVE

Truly own
your hardware.

We make open platforms for wearable technology and personal computing. Built in the open, made to be understood, repaired, and improved.

A FAMILY OF OPEN PLATFORMS

Hardware, on your terms.

One idea across two platforms: technology should be something you can shape, share, and call your own.
