The default firmware of the LR2 SE (ELRS 2.4G), LR3 (ELRS 2.4G) and LR3 Pro (ELRS 2.4G) manufactured by our company is ELRS V3 since Nov.20th.
The previous version, ELRS V2.0, which can be updated to ELRS V3.0 protocol firmware now.
If you want to upgrade your old radio controllers (LR2 SE and LR3), follow the steps below:
1. Download the corresponding firmware of the radio controller;
LiteRadio_3_SX1280_3.0.0_2023_11_07.bin
2. Download the BETAFPV Configurator V2.0.0-RC2 version, then install it;
https://github.com/BETAFPV/BETAFPV_Configurator/releases/tag/V2.0.0-RC2
3. Note: Only BETAFPV Configurator V2.0.0-RC2 version can be chosen if you want to configure
the radio controller, and you must select the serial port like the pictures below when
connecting to the configuration page.
Note:
After updating the ELRS V3.0, the LR3 Radio Transmitter ELRS no longer supports
external TX Module ! ! !
-------------------------------------------------------------------------------
If you want to upgrade your old radio controllers (LR3 Pro), please feel free to download the
firmware below.
After updating this firmware to a radio transmitter with old firmware (produced before Oct.17th,2023)
with a built-in TX Module, the following two things needs to be done if you need to use the external TX
Module Mode:
● The following two ELRSV3 scripts need to be added to adapt to external TX Module above V3.0;
● The baud rate of external TX Module protocol needs to be set to 921K or above, otherwise the
script cannot be entered;
Setting method: Ext-CRSF (external mode)----SETOP (setting)----External RF (external radio frequency
mode)----Baud rate: 921K
Note from BETAFPV:
If you encounter any issues or want to provide any feedback, please feel free to contact our tecnical support.

It works :)
It seems that many fuctions are still not working, such as the bind phrase, but otherwise it is ok.
Would be perfect if Wireless fuction of the ELRS module would work. This would enable easier updating of the module.
I was able to update my LiteRadio 3 to ELRS 3.0, but it doesn't allow me to input a binding phrase. This is using configurator V2.0 RC1.
Seems i update my LiteRadio 3 to ELRS 3.0 but i cannot connect BETAFPV Configurator V2.0-RC1 to config radio and already try with version v1.1.1-RC1
i flash to older version 2.0.1 but BETAFPV Configurator V2.0-RC1 doens't detect the port and i already install drivers
When I update my Literadio 2 se to RC1 the signal from gimbals is rubbish. I got the hall gimbals installed and it seems that they are not jet supported.
Would appreciate if this will be included soon.
For me (Literadio 3) the RC1 works; thanks a lot! I would appreciate, if a bind phrase would be supported in a future version.
@Janosch- I have the same setup. After updating I had to go through the calibration setup for the gimbals again and in the configurator it showed they worked correctly. However, I could not get the controller to work correctly in sims anymore even after calibrating.
Betafpv configurator V2.0 RC1 does not see/detect LR3. It does not see any serial device and hangs with 'loading'. And 'connect RC' does not work, and if go flasher and select fw manually - it does not do anything when I press 'flash'.
(note, 1.1.1 configurator can connect to my LR3, but also does not show device)
I have installed the STM drivers recommended in 'unable to see serial port' however it does not help. Note, device manager does not see unrecognized device, and if I delete 2.0.1 and install 1.1.1 - it can connect and configure my LR3 so I assume driver works
Got windows 11.
Can you please advice what is wrong?
The channel reversal function does not work, have you encountered it?
I upgraded my LiteRadio 3 but now I'm unable to put the transmitter into bindmode. It flashes red 3 times, then solid blue. Did the binding method change with this update?
@jeroen heymans
What windows do You have and what drivers used?
Have Yiu tried bind with pairing word?
Hi @Koolakoff. I have Windows 11, drivers I'm not sure I don't have my laptop with me now. But the flashing of the transmitter worked and can open it afterwords in the betafpv configurator. I just can't bind it with my drone (which is on ELRS V3). It seems the transmitter doesn't want to go into bindmode, as it only blinks red 3 times. I assume it's supposed to keep blinking until it found a receiver which it can bind with
I've flashed mine a few minutes ago, new configurator detects the controller and inputs but cannot detect the internal ELRS module so cannot bind or be configured. I've submitted feedback in hopes of moving things forward. I actually dug the remote out to sell it as all my kit is now ELRS 3 but this looks promising!
@jeron heymans what version you have on the receiver? you need version at least 3.0 on the receiver. Note you cannot add binding frase with this version because it's not supported yet. And another issue with this version you cannot play on the simulator the calibration have a bug
I have the Cetus X, below is the info from betaflight configurator. I also made a video of the pairing. It appears there is interaction between the transmitter and receiver, as the drone moves (in betaflight) when I push the bind button on the transmitter.

I saw the video. Well it’s strange maybe the support can help to solve this bugs. I have the cetus X aswell but I’m using a different controller because this new version Elrs v3 don’t give me benefits because I cannot used with simulator. I thing if you drowngraded to version v2 will not bind because you have new version of FC v4.4.2
BETAFPV Configurator V2.0-RC1 does not connect to my Literadio 3, however the BETAFPV Configurator V1.1 does connect to my controller.
This article says that I need BETAFPV Configurator V2.0-RC1.
