Parameters: for -receiver is based on the ExpressLRS project, an open-source RC link for RC applications. ExpressLRS 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. 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 protect RC models from being out of control. Besides, the plug-and-play design makes it easy and friendly to use. Note: To work with PWM receiver, make the TX and firmware is ELRS V2.0.0. Comparision in for ELRS Receivers What 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 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 -Receiver Material: plastic Color: as shown Beside, 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 .
