Found this a while back. Figured I’ll drop it here. https://fccid.io/YQD-EA00004/User-Manua ... al-4637253
It didn’t really help me much because I basically gutted the IOT and the controller.
I did hang on to the existing ESC / controller though. Just looking at the components, everything is there for it to run VESC. Gate/ motor drive chip is a TI chip but it’s actually better than ones used for VESC. FETs are really good as well. Also has three current shunts. The ST MCU should work just fine.
Wouldn’t surprise me if the existing FW is based or uses parts of VESC code.
I'm half tempted to flash VESC via SWD with a St link tool. I have too much crap going on at the moment.
