Hi,
i have a STM32 based ESC here, which has some version of the DRV-chip (gate driver) will this be enough to run the firmware? i checked the source code and a driver for this DRV chip exists
Provided, of course that changes is made to the source code regarding correct PINs etc etc
thanks
I have a rocket. Do you think it will be able to fly to the moon? The point is there is not enough info to answer you question. What STM32 version of the chip? Which DRV chip? What kind of voltage and current sensing is implemented?

We need some relevant information - what version of the chip are you using? These boards appear to be geared towards the STM32F4xx series processors. I believe the main criteria is that it uses the RTOS for that processor, and needs the higher frequency processor. As for the DRV chip - you don't necessarily need that chip - the newer firmware appears to work with just a simple FET driver, just update the firmware to reflect this change.
Hi,
sorry for replying late and for the lack of info! find two images of the PCB attached
MCU stm32f303
drv8323s Three-Phase Smart Gate Driver
tph2r608nh MOSFETs Silicon N-channel
From what i can tell, the board has three phase shunts (, i can also see testpoints for temp-sensing NTC.
Im feeling optimistic! but maybe i shouldnt?
Yes i know the PCB says "Bird" and that it is a rental scooter. However, Bird has stopped operating here and i managed to acquire a scooter that apparently was left behind.
Without looking any further, the MCU type will not work due a way small memory size. Vesc needs at least 384kb something and this MCU has 192k. There are other issues like MCU speed, etc. You may want to explore SimplFOC library that does support a variety of MCUs.
