EdgeTX Official Supported
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 brings much more features than traditional radios. Therefore, you can try your best to customize LiteRadio 3 Pro such as language, voice and etc with the EdgeTX system.
OLED Display Screen
OLED display screen with two 5D buttons is newly added to LiteRadio 3 Pro radio transmitter. Users can adjust the TX settings such as switching internal/external modules, gimbal calibration and binding on the screen by controlling 5D buttons. Compared with LiteRadio 3, it is easier to adjust such settings and very friendly to a new player.
EdgeTX Passthrough for ELRS Upgrade
With EdgeTX operating system, flashing ExpressLRS internal TX modules is easier for everyone. First, there is no need to disassemble the case. Compared with upgrading by WIFI, it is more convenient, fast, and stable to flash ELRS internal TX firmware by using EdgeTX passthrough flashing.
External TX Module
Nano module bay enables the external TX module available. LiteRadio 3 Pro reaches a high level with its capability 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 a high refresh rate, ultra-low latency, and long-range, is strongly recommended for LiteRadio 3 Pro.
