Frequently Asked Questions

Q: What transmitter modules are compatible with this 2.4G ELRS Nano receiver?

A: This receiver is compatible with any ExpressLRS (ELRS) 2.4G transmitter module running ELRS firmware. Popular compatible TX modules include those based on the SX1280/SX1281 chipset. Ensure your transmitter is also updated to ELRS firmware v3.0 or a compatible version for optimal performance.

Q: What is the maximum range of this ELRS 2.4G Nano receiver?

A: The effective range depends on your transmitter's output power, environmental conditions, and firmware packet rate settings. At lower packet rates (e.g., 50 Hz), the ELRS protocol is capable of multi-kilometre range. At higher rates (500 Hz), range is reduced in favor of ultra-low latency — perfect for proximity freestyle FPV flying.

Q: Can I flash or update the firmware on this receiver?

A: Yes. This receiver supports firmware flashing via the standard ExpressLRS configurator tool. It ships with firmware v3.0, and community firmware updates can be applied using the ELRS Configurator software over Wi-Fi or passthrough methods supported by the ESP8285 chip.

Q: Is this receiver suitable for micro or whoop-style FPV drones?

A: Absolutely. The Nano form factor and lightweight PCB design make this receiver an excellent choice for micro FPV builds, whoop-style frames, and compact freestyle rigs where space and weight are critical constraints.
