Funded and Stretch Goals Met

Thank you to those have backed us. In less than 24 hours after the launch of the campaign, we’d already reached our funding goal and both stretch goals!

Tomu is funded. That means we can start to source parts for the build, particularly the microcontroller with its long lead time. We’ve already met the stretch goal for the bootloader, which means everyone will get an easy-to-use bootloader to help with development. And we’ve met the stretch goal for the plastic case, which will make it easier to use Tomu out of the box.

Keep telling your friends about Tomu, to spread the love of tiny USB computers!
