Cheap FOCer! (VESC compatible 4.12 redesign) (Tested and Functional)

I tried to add some pictures on this post but it gave error when trying to send, and same when i tried to upload elsewhere and post link.

I tried to do some measuring on the board with wrong current measurement, i found that on R41 on DRV chip side is getting small voltage leaking from somewhere which explains the wrong current reporting. It also sometimes changes how much voltage there is, when the error was small i was able to run motor detection fine, but very soon after that it started giving DRV fault. Im really starting to feel like i have batch of bad DRV chips.

I have possibility to use hot air, but i desoldered few DRV chips with torch lighter when i didn’t want to wait to get access to hot air. I soldered most of them in place with soldering iron, which i feel like started going just fine after some practice. I did try soldering 1 with hot air but it left small balls of solder around the board so i just used soldering iron after that.
