The boss has great hands-on skills. What kind of camera did you use? And how did you take the photo?

This thing is quite expensive, what is the bracket used for?

More than 2000, put it directly on the table

I didn't expect that the air pump also has a circuit. It would be better to analyze the circuit.

There is nothing to analyze about just one MCU and one MOS.

What pressure does a car air pump need to have?

I have never seen this before. I just took a vague look at it in the repair department. What is this?

I don't know, I'll take it apart to see what chip it is.

Just the motor, nothing on the PCB

I see you are taking the photo from a low angle, without any camera, is that ok?

Yes, there is a platform on my desk. Just press it down.

The main reason is that the air pump driven by the motor is worn out, causing the pressure to not increase. I don't know what type of pressure sensor it is.
