Who can review the schematics of the BLDC control unit?

Question

Electronics

Hello everyone,

a review of the BLDC control unit schematics is required. I must say right away that the component base was chosen on the basis of what is available for purchase within a reasonable time. Here is a link to the project, everything is open source, I did the schematics in Eagle Cad.
Schematics of power supply and EBU This is connected as a result to a 36V battery and to a Chinese BLDC ZS-X11H (googled) . In general, I checked everything on breadboards, but I wanted to be 100% sure that there were no critical jambs before sending it to China for printing. Thanks in advance! PS: Answers can be both here and on GH.

Answer 1

Where is the ESD protection? Or do you think that static will not affect you? Yes, the first person who touches you when the hand is on the handle will disable input A0. Unless, of course, protection is not built-in (usually not).

Answer 2

You have an interesting style of using ground icons :)
In the regulator diagram, one end of C4 is hanging in the air. I don’t want to get into the code, but I would like all the gates of the field workers that are connected to the arduino to zero with a resistor so that there are no unexpected jokes.
The current through the LED can be limited, even though it is switched by a transistor.
Smart naming of connectors and circuits. There is a Vin connector near the buck converter, to which, as I understand it, your 36v come, the output voltage Vout from this converter is not used anywhere. Vin is set on the arduino ... At the same time, + 5V appeared on the arduino sheet. Where did it come from?
The Bat signal measures the battery voltage through such an interesting divider? Something I did not catch the idea, and even switching it with a shim.
Something I think is that on your breadboards, most likely, it looks a little like what is on the diagram.
