Currently the form factor of this module is designed for the JR-style module bay. Many of the popular RC transmitters use the JR-style module bay: FrSky Taranis, FlySky Th9x, Turnigy 9X/R/Pro
A fully assembled module + case available from Banggood.com here
Or
The ready-made module available here or here
Plus a module case that fits your module like the one here
or you can 3D print your own from a selection on Thingiverse (Example 1 Example 2).
For 9XR/9XR Pro, a new 3D printed module is available which makes use of the built in antenna in the handle. This means nothing is getting out of the radio back! You can find all details of this module case on Thingiverse.
If you are only planning on using the PPM interface with your transmitter, you need to connect it as described:
Some radios have an open collector output (Futaba, Graupner...), in this case you should add a 4.7K resistor between PPM and BATT.
The same plug is available on all versions of the module with the same signal locations.
If you wish to add an external device reading the telemetry, you need to enable serial mode as explained in the next topics otherwise you are now ready to go over to Compiling and Programming.
If you have a transmitter that can support serial communication with the board then you need to wire up the board appropriately. There are three versions of the module and the steps are slightly different.
Check which module you have and based on the pictures below. If you purchased the module after June 2016 then it is likely that you have a V1.1 type module. If you have purchased the version with case it is likely that you have a V1.2 type module.
Serial is already enabled and ready to be used.
Written on PCB back JRFM_V1.2
You are now ready to go over to Compiling and Programming.
Solder two bridges over the pads shown in the pictures below.
V1.1a
V1.1b
Written on PCB back 1.2
V1.1c
You are now ready to go over to Compiling and Programming.
Solder bridges and resistors as illustrated in the picture below.
If your module is always/sometime binding at power up without pressing the button replace the BIND led resistor (on the board back) of 1.2K by a 4.7K. Just to be safe it is recommended to do the modification anyway.
It's known that the A7105 of this version is not able to receive telemetry. The only protocol affected so far is AFHDS2A.
You are now ready to go over to Compiling and Programming.
