JR module bay



JR module bay is a semi-standard slot widely used in full-size radio controllers to plug an external radio transmitter or customize the controller.

The module is named after JR Propo, the company that introduced this kind of modules.

The bay includes five male pins to connect controller to the module. The original pinout is:
 * MOD / PPM (top)
 * +6V
 * VBAT
 * GND
 * ANT (bottom)

Some manufacturers use modifications of this pinout. For example, Taranis controllers typically use the following pinout:


 * CPPM
 * HB (Heartbeat)
 * VBAT
 * GND
 * SPort
