I just purchased a SkyID Remote ID Module SPMA9500. It comes with a couple interface cables for existing RV equipment and says it runs on 3 - 9 volts. I will be using this on a Mavic Platinum Pro and maybe on a Mavic Mini for P107 flights. I'm thinking I can run it on a 2032 coin battery. I emailed customer support and asked for a wiring diagram for the 4 pin plug that interfaces it along with an estimate on battery draw (ma/hr). They replied indicating they did not have either piece of information. I looked online but folks only address hooking these directly as a servo or similar in a R/C aircraft. Has anyone used these with drones and an external battery? If so, can you share your experiance?
