The ALL-UC4H Copter

The UAVCAN for Hobbyists or UC4H project has reached a milestone:

It allows us now to build an ArduPilot-based multicopter/drone, which uses only CANbus as communication backbone, and UAVCAN messages. No SPI, no I2C, no PWM, no ADC, only CANbus, UAVCAN and UC4H components. Moreover, and probably more relevant, this ALL-UC4H copter also provides highly useful and unprecedented features and functions, not available otherwise.

Also, the UC4H project is getting 2 years old now, and it’s a good time to celebrate its 2nd anniversary.

So I’ve decided to present the ALL-UC4H copter and its components and many features in a series of video episodes.
