BETAFPV Micro receiver is based on the ExpressLRS project, an open-source RC link for RC applications.
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.
ExpressLRS PWM Receivers
ExpressLRS now supports direct PWM output from receivers that have been specifically designed for this mode. BETAFPV ELRS Micro receiver features PWM output for the application of fixed-wing, helicopters, RC cars, 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 very easy and friendly to use.
Note: To work with PWM receiver, please make sure the TX and RX firmware is ELRS V2.0.0.
Comparision in BETAFPV ELRS Receivers
What is the major difference between Micro receiver, Nano receiver, and Lite receiver?
Micro receiver is the first ELRS receiver with PWM output on BETAFPV. It is widely used in fixed-wing, helicopters, RC cars, boats and etc. Weighing about 4.5g with an antenna means that a FPV drone can not afford to carry. With the plug-and-play connect ports, Micro receive is very easy to use and does not need to solder.
Nano receiver (2.4G version) is the first and (so far) the only receiver with power amplifier (PA+LNA). It has 100mW telemetry output and better sensitivity when longer range. Lite receiver doesn't have a PA/LNA on them, so its telemetry power is as what the RF chip SX1280 came with 17mW.
Beside, Nano receiver comes with normal external Dipole T antenna. Lite receiver has SMD ceramic antenna and in theory it is not so long range.
Micro receiver is used for fixed-wing, helicopter, RC cars, and boats. High recommend the Nano or Lite receiver to build on a drone. Especially on 65-85mm whoop drones with limited space and need lightweight, Lite receiver is a better choice.
