Hardware description: Opening transmiterAuthor El.Szaman
I REMIND YOU, I take no responsibility for possible damages. All modification You make on Your own risk!!!
Lets start from inspecting original transmitter. Unscrew 6 screws, then gently separate "upper" and "lower" part, disconnect multi pin connector from main board. Do not pull the cables, because they are fragile and not so solid clenched on connector. You can disconnect it using small flat screwdriver watching not to slip it, because it can easily damage electronic circus.
