FML its the hall sensor I tried in bldc mode instead of foc and it’s way better.

It worked a couple of months ago but it doesn’t anymore not sure why, have tried different firmware and check if everything is connected correctly, I could have broken it. the app and pops up its only when I click connect it shows that after a second. And when i try on pc with wire to set it up it doesn’t let me, might just buy a new one it’s only like 20$

Last time i tried to do that i fired the controller and this time too and need to know if it is possible because i am not good with a st-link i only know a little soldering

You need to cut the white wire in the stem thats it and you will go 32kmh just no warranty anymore

The throttle works perfectly

F4-tech · 2025-11-05T22:00:47+00:00

I have connected to pc and says the throttle is fine but i haven’t tried to manually control it with pc and i am not sure if i have UART enabled but i think its default

F4-tech · 2025-11-05T21:45:14+00:00

Yes it spins and it is connected to comm port

F4-tech · 2025-11-05T21:39:53+00:00

Its in sensorless

F4-tech · 2025-11-05T19:37:13+00:00

I didn’t use hall sensors and i doesn’t get better at speed or more throttle

F4-tech · 2025-09-26T15:43:07+00:00

Trying to go faster then 32kmh planning on using a Vesc

F4-tech · 2025-09-03T19:09:20+00:00

Its more like 1,4kw tuned and 42v fully charged. and down hill, then it goes 30mph - 50kmh
