DC 12V-36V 500W Brushless Motor Controller Without Hall PWM Control Balanced Car Driver Board

I am building a robot and it needs a lot of work, I have no complaints.

I connected it to bldc and it didn't work. If I turn the engine a little, it will work. The stage and the lobby are connected correctly, please help.

It is working but does not accurately describe how the output frequency / voltage is generated. Adding a suitable cooler is difficult because the transistor must bend to subtract a point. Other: The control head has a pitch of 1/10 "and the power head is 5 mm (not 5.08 or 2/10"). The 5 V on the connector is the output of a potentiometer or other application. Do not feed it with 5V.

It works very well It looks quiet, efficient and easy to set up.

I bought two of these to pair with some brushless DC hall motors. The board quality is acceptable and both boards worked when attached between a raspberry pi zero and the motors. I accidentally set one on a small metal rod but didn't notice it before powering the board and it immediately shorted out. It was entirely my fault but disappointing I was able to short it so easy.
