These days, where can I buy well made APM boards?
Support for APM boards has ended almost 2 years ago. So no more features or updates are coming for those.
If you still need APM2.6 boards. jDrones who is one of the original creator of ArduCopter and APM’s might have and if you need bigger quantity they can make those.
jDrones is making all other parts too and is supporting Ardupilot organization and Ardupilot development. A good and preferred source.
I was wondering - could someone help me finding the schematics or at least the pinout of the APM 2.8 (or 2.6). Does someone still have an archive?
