I received two VESCs from China, one works like a charm, the other seems to have a defect on the DRV chip. As far as I know you can replace the chip with a heat gun / hot air soldering. I had some bullet connectors on the output wires, but these were separated again. I made cutouts in the heat shrink for the USB and Hall Sensors.
Hall sensor cable and Mini USB cable included!
Images will follow when I’m home again
Price:
I know I have to include a price, I really don’t know how much work it is to replace the DRV chip, according to tutorials it seems to be pretty straight forward and quick, if you have a soldering hot air gun. A new one is like 60-70€ atm from FlipSky, but there’s one for 60€ from maytech that should be at least as good.
So my asking price is 40€, this should turn out cheaper than a new one, also you’ll get it faster
Especially if you live in Germany. I would also accept repair services for the DRV issue!
Remember there could be more wrong with it than a single chip. Posting high-res photos of both sides of the circuit board can drastically help as well.
Well New it’s 60€ to 70€ now. But yeah you’re absolutely right, shipping to America would make a horrible deal
Of course this price is negotiable if one lists arguments. Can add more pictures on request I personally can’t find any burn marks
It seems like sometimes a broken DRV destroys MOSFETS too. In the debug terminal, there was only a DRV_ERROR but I can’t promise that all MOSFETS are working. The FOC noise making test worked, but you can’t read things like R and L from the motors…
