Product overview
The iFlight ExpressLRS ELRS Receiver is a receiver module developed in cooperation with the ExpressLRS Team. Its improved circuit design measures 12*19.5mm and weighs 1.2g. The receiver operates on a 5V input, uses the CRSF protocol and provides a 5V, GND, RX and TX interface. A pre-soldered SH1.25 connector with 30mm wire supports plug-and-play installation with iFlight flight controllers. The 2.4G configuration uses ExpressLRS iFlight 2400RX firmware, operates in the 2.4GHz ISM band and provides 20dbm telemetry power.
The 2400MHz band supports a packet rate up to 500hz. Antenna choices include frequency-tuned T-style dipoles and SMD antennas, with 70mm, 40mm and 220mm Mini Antenna configurations for the 2.4G RX. The 2.4G antenna connection uses IPEX, while the SMD antenna configuration uses a Molex 479480001 SMD antenna. Install the antenna away from conductive or magnetic components, including carbon, metal and motors. The package supplies one ExpressLRS Receiver and one antenna.
