will the FrSky module work on my JR 622?

changed status

It most likely will,  It is made for JR expansion ports, however, the JR 622 is an older radio, and I am unable to find photos of the expansion bay.


The Frsky module such as the DJT will work with most radios with a PWM output and the JR standard expansion bay.

Let me know if that helps to answer your questions!
