ExpressLRS Power for Traditional Models
While most ELRS receivers are designed for drones with serial protocols, the BETAFPV Micro Receiver brings the power of ExpressLRS to the world of PWM. It converts the high-speed digital signal into 5 standard PWM channels, allowing you to plug servos and ESCs directly into the receiver. This makes it the perfect choice for fixed-wing aircraft, helicopters, and RC boats.
Effortless Setup & WiFi Updates
No soldering is required! The receiver features standard pin headers for a quick “plug-and-play” experience. It also comes equipped with built-in WiFi, allowing you to update firmware or change settings via the ExpressLRS web configurator on your phone or PC. The onboard LED provides instant visual feedback on binding status and connection strength.
Compact & Wide Voltage Support
Despite its advanced features, this receiver remains incredibly lightweight at just 4.5g. It supports a wide input voltage range of 5V to 9V, making it compatible with most standard BECs and power systems used in the hobby today.
