Tessel 2 is designed for the fastest possible path to production. Plug and play modules and high-level APIs set it apart from most other development boards. Tessel doesn't expect you to set up and maintain a Linux system or track down pinout diagrams to wire up sensors (though the root shell and GPIO access are available should you desire them).

Yes. First-party modules will have high-level APIs and be tested to ensure driver support, but you can also add your own USB devices if the drivers are compatible and/or you dive a little deeper into the OpenWrt ecosystem.

No, Tessel is not structured as a conventional company. Initially, the Tessel board was introduced by a startup called Technical Machine. It has since evolved into an independent, volunteer-driven entity known as the Tessel Project. For those with inquiries, Tessel can be reached via Twitter at @tesselproject. More detailed questions can be addressed on the forums. For order-related queries, Seeed Studio is the point of contact.

Despite the cessation of its original production, the enthusiasm and passion of the community have not waned. Recognizing this, Bairesdev has taken the initiative to revive the Tessel board, catering to the community's continued interest and support.
