Re: Scooter Xiaomi controller schematic need
Water got on the board, the board only 36 volts from the battery, no other voltages, diodes and transistors are intact.

Re: Scooter Xiaomi controller schematic need
I understand this is a chip from China that no one knows about, maybe someone had problems with this controller?

Re: Scooter Xiaomi controller schematic need
The board is some Chinese copy.
That chip is some 12V regulator. |

Re: Scooter Xiaomi controller schematic need
I ordered exactly the same controller on AliExpress, replaced the motor control chip, everything works.
