2000 Boards Backed

Tomu has crossed an important milestone: More than 1000 boards have been ordered by you, our supporters. In fact, not only did we reach the 1000 unit milestone, we went even further and passed the 2000 mark! That’s more than 2000 USB ports that will now have a computer inside them. Thank you for your support!

There has been an incredible response from the community. Many have come out to help with the firmware, and there has been a lot of software made available. We’re looking forward to see what you do with these boards once you get them, but for now keep spreading the word about Tomu, and the world of tiny USB computers.
