Official EdgeTX support
LiteRadio 3 Pro Radio Transmitter: An open source radio remote control that supports the EdgeTX system, which is an open source firmware for RC radio transmitters. The firmware is highly configurable and offers many more features than traditional radios. Therefore, you can try your best to customize LiteRadio 3 Pro such as language, voice and so on with EdgeTX system.
Note: Click here to learn more about the EdgeTX operating system.
OLED screen
OLED screen with two 5D buttons has just been added to the LiteRadio 3 Pro radio transmitter. Users can adjust TX settings such as internal/external module switching, gimbal calibration and on-screen binding by controlling the 5D buttons. Compared to LiteRadio 3, it is easier to adjust those settings and very friendly for a new player.
EdgeTX passthrough for ELRS update
With EdgeTX OS, flashing ExpressLRS internal TX modules is easier for everyone. First, you don't need to disassemble the case. Compared to updating via WIFI, it is more convenient, faster and stable to flash ELRS internal TX firmware using EdgeTX passthrough flashing.
Note: Click here to know the update steps. Passthrough is only used for ELRS 2.4G version. Currently, BETAFPV is actively communicating with the official ExpressLRS team on the latest ExpressLRS configurator to support flashing LiteRadio 3 Pro ELRS TX firmware.
External TX module
The nano module slot allows you to have the external TX module. LiteRadio 3 Pro reaches a high level with its ability to support multi-brand external TX modules in the market for different protocols such as MULTI, CRSF, PPM, XJT, DSM2 and R9M, etc. BETAFPV ELRS Nano TX module, which features high refresh rate, ultra-low latency and long range, is strongly recommended for LiteRadio 3 Pro.
Note: If you are ready to install the external TBS nano module, the size of the TBS nano module case should be 64*42*25mm, the thickest one of the retrofit cases.
Cardan room
Features four precision bearings, adjustable spring tension and ergonomic stick ends for an unmatched feel. With an adjustable stick end, it fits your thumbs perfectly and greatly improves the feel of the stick for control. The Hall effect provides non-contact sensing not only for accurate control inputs and precise centering, but also for durable use.
