Microreceiver BETAFPV ELRS

BETAFPV ELRS Micro Receiver is a versatile receiver based on the ExpressLRS open-source project, known for its high speed, low latency, and excellent communication range. This receiver differs from other BETAFPV models in that it supports not only the CRSF protocol, but also direct PWM output. This makes it an ideal choice for a wide range of RC models, including airplanes, helicopters, cars, and boats, not just FPV drones.

Thanks to support for 5 PWM channels and a failsafe function, the ELRS Micro Receiver provides reliable control and protects your model from loss of control upon signal loss. It features a plug-and-play design, making it easy to use even for beginners.

Advantages and Features:

PWM output: Support for direct PWM signal output makes it ideal for models that do not use flight controllers with CRSF protocol (for example, airplanes with servos).

Wide compatibility: The receiver is suitable for multirotors, fixed-wing aircraft, helicopters, RC cars, and boats.

Failsafe: Reliable failsafe function allows you to configure model behavior upon signal loss, preventing flyaways or crashes.

Simple binding process: Thanks to a convenient binding procedure (power cycling three times), the receiver is easy to set up.

CRSF support: The receiver can also be flashed to work in CRSF mode, expanding its functionality.

LED Indication:

Solid light: Successful connection.

Fast double blinking: Binding mode.

Slow blinking: Loss of connection.

Fast blinking: WiFi firmware update mode.
