iRangeX IRX4 Plus 2.4G CC2500 NRF24L01 A7105 CYRF6936 4 IN 1 Multiprotocol ARM TX Module With Case
A part of the review has been auto-translated.
I just had to have the IRX4+ after having owned the IRX4 for several months . I only have the Flysky 9x with stock factory firmware that the IRX4+ can plug into . And it does plug in with no issues . The IRX4+ case has been changed / upgraded to allow insertion into the back of the 9x ( Flysky ) . I was easily able to bind the 9x to my JJRC H36 and have a quick fly . I then put the IRX4+ in my Taranis Q x7 and flew the JJRC H36 again . If you are looking for a multi protocol module for your 9x / 9XR / 9XR pro and you dont want to flash the firmware . Then the IRX4+ is the module you want .
With the new documentation of it's creator, Pascal Langer, this module is easy to flash via the USB port : https://github.com/pascallanger/DIY-Multiprotocol-TX-Module/blob/master/docs/Compiling_STM32.md
