jDrones are now manufacturing and selling some open source UAVCAN hardware originally developed by OlliW: http://store.jdrones.com/uavcan_electronics_jdrones_s/314.htm
Good to see things moving; although that makes me worried that every such development makes the upcoming push to v1.0 harder.
Is the firmware for this board open source?
Unless I’m missing something obvious the source doesn’t seem to be available. Everything else is on GitHub though. https://github.com/olliw42/uavcan4hobbyists
Indeed. Perhaps you should get in touch with Olli and ask him directly?
I asked but got no response from OlliW. AFAIK, it’s his own personal toy project and in no way he has intentions to open-source its firmware.
