You have the polarity of the zener wrong, that way it will only drop ~0.7V

You should have the band on the zener towards your (+)

Okay, thanks. I corrected the picture. Do you know if the Z-Diode with 1.3W is enough? And will the ZENER get very hot?

Hi to all, today I have flashing a ESP32 with the last repository on github
https://github.com/chappy1978/ES200-Sco ... tree/Final
and,unfortunately, on my es200G only one flash light on rear light when turn on the scooter from the app... nothing else!
Someone to help?
I have used VSC for flashing and its all ok

or take several diodes in throughput direction in series, works also. (500-700mV per regular silicon diode)
There will be no big current and therefore no big in rush at all. The biggest option would be when using a ESP32 for example but even that chips doesn't draw more than 200mA @ 3,3V. The LM2596 has a converting efficiency around 94% plus it takes approximately 5-8mA to power itself so if you lower the input voltage about 10V we're talking about 17-32 volt to the regulator what is within its operating range. 200mA @ 3,3V= 660mW, 660mW divided by 0.94~=702.1mW, for the highest current we take 17V as lowest case so 702.1mW divided by 17V = 4,13mA, 4,13ma plus 8mA selfpower is 12,13mA, 10V diodes loss times 12,13mA = 121,3mW loss in heat on the diode when powering a ESP32 in full load giving approximately 88% safety factor when using a 10V 1W type.
Cheers

Try the Final Branch of my firmware that’s the most up to date.

This with your last firmware and the same result...

Amazing !
I've tested myself to change the 1st, 2nd and 5th bit of the 4th Byte.
I think I found what is the use of the 1st one.
Looks like it is a "Turbo" mode. If you put it a 0 you will have standard and linear acceleration. But when this value is 1, you get like a second acceleration after the first one. Give you a little more punch an allow you to go faster.
For the 2nd and 5th, I did not notice any difference ...
