Parameters: for -receiver is based on the ExpressLRS project, an open-source RC link for RC applications. ExpressLRS to achieve the 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.ExpressLRS now supports direct PWM output from receivers that have been specifically designed for this mode. for ELRS -receiver features PWM output for the application of fixed-wing, helicopters, RC , boats and etc, and supports failsafe function, which can RC models from being out of control. Besides, the plug-and-play design makes it very easy and friendly to use.Note: To work with PWM receiver, please make the TX and firmware is ELRS V2.0.0. Comparision in for ELRS ReceiversWhat is the major difference between -receiver, Nano receiver, and Lite receiver? -receiver is the first ELRS receiver with PWM output on for . It is widely used in fixed-wing, helicopters, RC , boats and etc. Weighing about 4.5g with an antenna means that a FPV drone can not to carry. With the plug-and-play connect ports, -receive is very easy to use and does not need to solder.Nano receiver (2.4G version) is the first and (so ) the only receiver with power amplifier (PA+LNA). It has 100mW telemetry output and better sensitivity when range. Lite receiver doesn't have a PA/LNA on , so telemetry power is as what the RF chip SX1280 came with 17mW.Item: for ELRS -ReceiverMaterial: plasticColor: as shownBeside, Nano receiver comes with normal external Dipole T antenna. Lite receiver has SMD ceramic antenna and in it is not so long range.-receiver is used for fixed-wing, helicopter, RC , and boats. High mmend the Nano or Lite receiver to on a drone. Especially on 65-85mm whoop drones with limited space and need lightweight, Lite receiver is a .Item: for ELRS -ReceiverWeight: 4.5g (with antenna)Antenna: IPEX MHF + T antenna (recommend 80mm Dipole T Antenna)PWM channel: 5 channelsSerial output protocol: PWM or CRSFSize: 19mm x 32mm x 9mm (without antenna)MCU: ESP8285/SX1280/SX1281Telemetry power: 12.5dbm/17mWFrequency bands: 2.4GHz Input voltage: 5V~9V DC @ "+" padDefault firmware version: ExpressLRS v2.0Adapted RC Model Type: Multirotors, Fixed-wing , Helicopters, RC , RC Boats and etc.Package contents:1 x 2.4GHz ReceiverOnly the above package content, other are not included.Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing.
