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.

Note: The passthrough is only used for ELRS 2.4G version. Currently, BETAFPV is actively communicating with the ExpressLRS official team on the latest ExpressLRS configurator to support flashing LiteRadio 3 Pro ELRS TX firmware.

Nano module bay enables the external TX module available. LiteRadio 3 Pro reaches a prominent 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.

Note: If you are ready to install the TBS external nano module, the TBS nano module case size should be 64*42*25mm, the thicker one of the retrofit cases.
