TEST: iRangeX IRX4+ external RF multimodule

null

INTRODUCTION

The iRangeX IRX4+ is nothing else than the new revision of the super popular Banggood 4-in-1 multimodule dedicaced to all radios able to receive an external radio module at least in PPM mode.
Here, the iRangeX IRX+4 welcomes the revision 1.2 of the board. We still have the possibility to select up to 31 different protocols via the dial button located rear or even more protocols if the communication between the radio and the module can be done via a serial link. This second way is clearly only compatible with all modern radios supporting OpenTX 2.2. Thanks to this module, you can transform a lot of radios into quasi-universal radios.

OVERVIEW

The module comes with a high quality plastic casing… super easy to clips into any recent compatible radios via the 4 pins serial connexion.

We have a central yellow dial to select up to 31 protocols divided into a first batch of 15 protocol and a second set of 16. On the right, a miniUSB port to update the builtin firmware.
There are also two lights. The red left one shows the powerstatus as soon as the multimodule is used. The right green one indicates in which protocol bank is currently selected. When the light is off, we can select a protocol from 1-15. When turned on, protocols from 16-31.

null

To cycle between protocol banks for PPM connexion, you need first to install the dial in “0” position, then press & hold the bind button while powering the radio during 3-4s.

The 4-in-1 multimodule is the main one with the metallic shielding. On the top left, four free pads to welcome the pin header provied. A small soldering job is required.

Below, the BOOT0 pads to be jumped to flash a new bootloader.

The IRX4+ comes with the board in version 1.2 compared to the 1.0 for the original Banggood product.

UNBOXING, PPM and SERIAL TESTING

The module works flawless out of the box in PPM mode. For some protocols, you will need to manually bind by press & hold the bind button while turning the radio. For some other, the protocol is defined with an antobinding so … you just need to turn on the radio. The yellow dial is small and the “0” reference should by highlighted with a marker pen.

As long your radio got a recent openTX release, the module can talk with the radio in serial mode if the the dial is in “0” position. You must first turn off the internal RF module and select the “MULT” external module option as soon as the OpenTX module is flashed with the “multimodule” option. With the serial connexion, more protocol are available as sub-options some others.

CONCLUSIONS

Definitively, the must to have external RF module… Compatible with ton of radios at least in PPM. Clearly the module is super great to use with OpenTX and a serial link. A Higly recommended product.

PROS

+ Support both PPM & serial connexions
+ Compatible with a lot of existing radios
+ Dial protocol selection for PPM connexion
+ Mini-USB port for more easy fimrware upgrade

CONS

This radio multimodule have been courtesy provided by Banggood in order to make a fair and not biased review. I would like to thank them for this attitude.
You can find it actually for 36.5USD at https://www.banggood.com/IRangeX-IRX4-Plus-2_4G-CC2500-NRF24L01-A7105-CYRF6936-4-IN-1-Multiprotocol-STM32-TX-Module-With-Case-p-1225080.html

    Hey Seb,

    Any chance of documenting how the firmware update is done over USB?

    Cheers,
    Wayne

      I plan a part 2 with the firware update done by USB … but actually the drivers required to see the USB port doesn’t work… so I am blocked. As soon I will find the trick, I will do this part 2.

  • Mark Inwards says:

    I’m having trouble binding to flysky receivers using this module in a qx7 do you have any ideas how to do it please mate?

    • SeByDocKy says:

      Ok … for some A7105 protocols sometimes it need to apply a bias to the main carrier… In the last deviationTX build, all associated protocols got now this suboption… Don’t know it it’s the case yet for the DIY module but if it’s the case in anycase, a new firmware must be reflashed….

      • Mark Inwards says:

        Thanks for the reply but I have no idea what you mean lol!

        Flashing new firmware looks like a nightmare! Why does the plus have the USB connection if you have to take it apart and solder all those bits anyway.

        I had a look at the flashing page but it looked way over my head…

        The only response I get is using the fs 2a protocol and it will take the flysky receivers out of bind mode but not actually bind to them

    Hello SebyDocky…
    I want to ask you if u can….we are many owners
    Of hubsan h122d storm ( team from global Facebook group ) that we want to buy this module for taranis to bind it with storm…
    Can u tell me if this work with hubsan Storm?can u make a test for us?
    I will appreciate it a lot!im waiting for your answer 🙂

  • Nick Palmantouras says:

    Thank you a lot for this video!from me and all Group!

  • Jeff Brown says:

    Are you supposed to loose the failsafe when you use this module, or did I do something wrong? Can’t find it is serial mode, or PPM mode as soon as I turn off the internal RF the failsafe disappears.

    • SeByDocKy says:

      I am not a specialist of this module, but no F/S suboption associated with each protocol ? In PPM mode, the bind button can’t be use to set the F/S ?
