Mini_SimpleFOC brushless motor drive and control integrated board

The PCB size of this project is just right to fit the 4010 and 4008 gimbal motors sold on Taobao. You can also change the PCB size to accommodate more brushless motors according to your needs.
Voltage-based speed loop and angle loop control are now implemented.
I used automatic routing for PCB routing, and only thickened the power supply routing, so the routing would appear messy and unreasonable. But it does not affect normal use, and you can also wire it yourself as needed.

The board only provides serial port downloading. Each time you download a program, you need to toggle the switch to pull BOOT0 high and then press the reset button. After the download is completed, BOOT0 needs to be pulled low to run the program normally.

The cost of a set should be between 20 and 30 yuan (if all common components are available)

The pid parameters of the speed loop and angle loop can be modified in the software program

The maximum voltage value in the main program must not be set too high, preferably below 5, otherwise the motor may burn (directly -50)

The picture below shows the brushless motor of the gimbal suitable for this project (available on Taobao)

The back of the board is as shown below, mainly the 12-3.3 LDO buck chip and the magnetic encoder as5600

Below is the overall picture, the copper pillars are M2*6+4
