ExpressLRS aims to achieve the best possible link performance in both speeds, latency, and range. This makes ExpressLRS one of the fastest RC links available while still offering long-range performance.\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eWeight: 0.7g (receiver only)\u003c\/li\u003e\n\u003cli\u003eSize: 12mm*19mm\u003c\/li\u003e\n\u003cli\u003eTelemetry power: 20dbm (100mW, 2.4G Version)\u003c\/li\u003e\n\u003cli\u003eFrequency bands (2.4G version): 2.4GHz ISM\u003c\/li\u003e\n\u003cli\u003eFrequency bands (915MHz\/868MHz version): 915MHz FCC\/868MHz EU\u003c\/li\u003e\n\u003cli\u003eInput voltage: 5V\u003c\/li\u003e\n\u003cli\u003eAntenna connector: U.FL MHF\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eConfiguration \u0026amp; Bind \u003c\/h2\u003e\n\u003cp\u003eExpressLRS uses the Crossfire serial protocol (AKA CRSF protocol) to communicate between the receiver and the flight controller board. So make sure your flight controller board supports the CRSF serial protocol. Next, we use the flight controller with Betaflight firmware to show how to set up the CRSF protocol.\u003c\/p\u003e\n\u003cp\u003eThe connection between the ELRS Nano receiver and the FC board is shown below.\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopifycdn.net\/s\/files\/1\/1778\/6615\/files\/1_323dda3c-f490-430c-8858-e7b1b0e5937a.png?v=1626253445\"\u003e\u003c\/p\u003e\n\u003cp\u003eEnable the corresponding UART (e.g. UART3 below) as a Serial Rx on Betaflight Configurator \"Ports\" tab.\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopifycdn.net\/s\/files\/1\/1778\/6615\/files\/2_39841eac-9d0e-4d23-8c5b-d2c7e1eafde2.png?v=1626253468\" width=\"334\" height=\"121\"\u003e\u003c\/p\u003e\n\u003cp\u003eOn the \"Configuration\" tab, select \"Serial-based receiver\" on the \"Receiver\" panel, and select \"CRSF\" as the protocol.
