ELRS Nano RF TX Module High Refresh Rate Long Range Performance Ultra Low Latency for FPV RC Radio Transmitter with Nano Module Bay Like Frsky Taranis X-Lite X9D Lite TBS Tango 2 - 2.4GHz
【ExpressLRS】ExpressLRS is an open source RC link for RC applications. It is based on SX127x/SX1280 hardware combined with an ESP8285, ESP32 or STM32 for RX and TX respectively. It aims to achieve the best possible link preformance in both speed/latency and range
【Protocol】ExpressLRS uses the Crossfire serial protocol (AKA CRSF protocol) to communicate between the radio transmitter and the Nano TX module. So make sure your radio transmitter supports the CRSF serial protocol
【Bind&Output Power】Nano TX module could enter binding status or switching the output power via ELRS. Lua script, as described in the "LUA Script" chapter. Besides, a short press button on the module could also enter binding status, long-press the button on the module could switch the output power
