Not sure if this has been posted here yet (I did a search for Sarawuth and nothing came up), but I just did this mod and it allowed me to install a canbus connector on the Phantom upgrade board. Using this mod I was able to ditch both the PMUv2 and the zenmuse module (saving me much weight) but keep my iosd mini!
