Controller that drives BLDC motor as servo
More details to come, for now this is just a placeholder informing that this is a motor driver microcontroller board that can be attached to a 3-phase BLDC motor (such as a camera gimbal) and control it via RS485 protocol. It receives torque commands and sends back the angular position read via magnetic sensor.

Questions
How big is the Motor PCB?
It measures 45 × 45 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Motor use?
48 parts, built around the STSPIN32F0, RS485, PSMN3R3-40YS and CD0603-B0340R. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Motor KiCad files?
From the DizzyRobot/DirectServo repository on GitHub, at the commit this page was made from: the board is Schematic/motor.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Motor design in my own project?
Its repository states no licence, so its author keeps all rights: ask DizzyRobot before reusing the design.
