Very fine work, and bridged soldering of 2 pins is intentional. Here’s (not much but a little) better shot of how burnt the poor FT232 chip is… blurry but you can see the discoloration… Without getting into reverse engineering their schematic I’m guessing they have something setup very inefficiently so it is shunting tons of current to generate the 5V but I dunno. The big device they use turns out to be an L7805V voltage regulator. Tools needed: ICOM Rheingold engineering software INPA, NCS expert (and others WinKFP, Ediabas etc) WIFI BMW ICOM A2 emulator or BMW INPA K+DCAN cable. Pic below doesn’t quite do justice to how burned that thing looks in person. If I end up with another one I will cut those back and cover in hot glue or something to isolate from the FT232 chip. In fact it has fresh burn marks on it making me pretty sure an arc from those is what took out the cable. Typical terrible Chinese layout PCB design. I can’t help complaining the bad K+DCAN cable I used before.
