ELRS Airport Firmware
An open-source, high-performance radio control link for FPV drones, offering best-in-class range and latency using LoRa modulation.
What is ELRS Airport Firmware?
ExpressLRS is an open-source radio control link system designed for FPV (First Person View) drones and RC applications. It uses LoRa modulation combined with optimized packet structures to deliver best-in-class range and ultra-low latency, making it ideal for high-speed racing and reliable control. The system supports multiple frequency bands (900 MHz and 2.4 GHz) and a wide range of hardware from various manufacturers.
FPV drone racers, RC hobbyists, and developers working on custom radio control systems who require high-performance, low-latency communication links for precise control and telemetry.
Developers choose ExpressLRS for its open-source nature, community-driven development, and superior performance in range and latency compared to proprietary RC links. Its support for multiple hardware targets and frequency bands offers flexibility, while features like wireless updates and bind phrases enhance user convenience.
