Any updates? Really looking forward to seeing where this board goes.
Nope. Still waiting for the shipment, more than a month. China is mostly shut down due to COVID zero tolerance policy. My orders have been frozen for 4 weeks already.
Hello,
hereās the next guy who stumbled across this thread on his endless search for the mystic <10$ high power FOC controller.
@Valentine Have you received the boards by any chance? 
yes. that post is two years old. please check my other posts. cheers, valentine
Well it is fundamentally possible to reprogram these things, and there is open source software for them, blheli_S. I in fact did buy some boards and did reprogram them, however it would not make sense to put the work in to make better firmware. Probably, modifying Bl_heli_s could have worked for my purposes. However even that I donāt want to be doing as there is now a promising avenue to a good flagship board for simplefoc lined up.
