Frequently Asked Questions

What is the operating voltage for the SpeedyBee Nano ELRS Receiver?

The SpeedyBee Nano ELRS Receiver operates at 5V. It is crucial to provide a stable 5V supply, typically from your flight controller's BEC or a regulated power source, to ensure proper function and avoid damage to the sensitive RF components.

Can I update the firmware on this receiver, and how?

Yes, the receiver is fully compatible with the open-source ExpressLRS firmware. You can update it using the ExpressLRS Configurator via Wi-Fi (using its built-in ESP8285) or via a serial passthrough connection from your flight controller to install the latest performance enhancements and features.

What is the effective range of this nano receiver?

While range depends on antenna placement, output power, and environmental factors, the SpeedyBee Nano receiver, with its ~120mW output and ExpressLRS protocol, is capable of several kilometers in open space. For micro drones typically flown closer, it provides a robust and reliable link far beyond visual line of sight.

Is this receiver compatible with my ExpressLRS 2.4GHz transmitter?

Yes, it is fully compatible with any ExpressLRS 2.4GHz transmitter (e.g., RadioMaster, HappyModel, BetaFPV) running the same major firmware version. Ensure both your transmitter module and this receiver are flashed with the same ExpressLRS firmware version for binding and optimal performance.
