How to identify the common port of a 4-wire motor:
Use the resistance * 1 position of the multimeter to measure the four terminals separately.
If the resistance value of one terminal is the smallest and equal to that of the other three terminals, then this terminal is the COM terminal, which is the common terminal.
The driver board automatically identifies 3-wire or 4-wire brushless motors,
4-wire brushless motors can also be connected without COM lines.
