I would like to know if anybody have an technical explication of my probleme or can help me.
To know wat is going on my ES200G controler :
I have Buck convertor to the Red (VIN) and black wires (GND)

I connect it on an ESP32 whithin RemoteXY code. All done ! The ES200 D is running very well.
The problem appear after 3 weeks. The red wire dont have any voltage between black and red...
I have a second scooter for spare, the same issue on some weeks... 2 controllers KO whith
this connection. I suspect the Buck conertor. But i don't know why?? Have you an idea? when i charge the scooter, the display shows the load and no error but whatever I communicate with the RX pin of the controller like before nothing happens, the scooter don't turn on. :-(
Maybe an security of the controler? Reflash can maybe help...
The buck convertor is consuming more than the capability of the controler can offer ?
Before i use this buck convertor, i use powerbank and all are done... strange...
thx for reading and may be helping.
