Hey guys - I am in he process of installing the zenmuse h3-2d. watching DJI's video - #1 I've installed the upgrade kit, the video doesn't look like they are installing on an upgraded MC. #2 - It shows I have to solder the "PMU of Naza-M V2" on the circuit board. I don't have that! I was under the impression that all I needed was the upgrade kit and the Zenmuse H3-2D. I just want to make sure I don't screw this up!
