The Espruino software and hardware is Open Source. While many members of the community work hard to improve and maintain the software, ultimately the boring day to day work needed to keep Espruino working well is done by us, and we're supported purely by sales of Espruino boards and donations.
Espruino runs on all the boards below and many more besides, completely free of charge.
Please help us keep it that way! Click Donate below so we can keep improving Espruino and supporting our users!
