Transmitter Module Pinout
I would like to put one of JR's transmitter modules in another transmitter. The module I have is JR's JRPTXMF for 53Mhz, A1. The connector has 5 pins, the ground, antenna, and + voltage are obvious but I surprised to find 2 more. The XP 6102 has only one additional pin which I assume is the signal in. Can you help me here?
