Official EdgeTX Support
LiteRadio 3 Pro Radio Transmitter: An open source radio remote control that supports EdgeTX system, which is an open source firmware for RC radio transmitters. The firmware is highly configurable and offers much more features than traditional radios. Therefore, you can do your best to customize LiteRadio 3 Pro like language, voice and so on with EdgeTX system.
Note: Click here to learn more about the EdgeTX operating system.
OLED screen
The OLED screen with two 5D buttons is newly added to LiteRadio 3 Pro radio transmitter. Users can adjust TX settings such as internal/external module switching, gimbal calibration and binding on the screen by controlling the 5D buttons. Compared with LiteRadio 3, it is easier to adjust such 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, there is no need to disassemble the case. Compared with WIFI upgrade, it is more convenient, faster and more stable to flash ELRS internal TX firmware using EdgeTX passthrough flashing.
Note: Click here to learn the update steps. Passthrough is only used for ELRS 2.4G version. Currently, BETAFPV is actively communicating with the official ExpressLRS team about the latest ExpressLRS configurator to support flashing LiteRadio 3 Pro ELRS TX firmware.
External TX module
The nano module housing allows for external TX module. LiteRadio 3 Pro reaches a high level with its ability to support multi-brand external TX modules on 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 highly recommended for LiteRadio 3 Pro.
Note: If you are ready to install TBS external nano module, the size of TBS nano module case should be 64*42*25mm, the thickest one of retrofit cases.
Cardan Hall
It features four precision bearings, adjustable spring tension, and ergonomic stick ends for an unparalleled 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.
