ExpressLRS is an open source radio control link firmware for RC applications, built on Semtech SX127x/SX1280 LoRa hardware with Espressif or STM32 processors. It provides best-in-class range and latency for FPV racing and long-range drone flying, supporting 900 MHz and 2.4 GHz links with packet rates up to 1000 Hz.
Use cases
- fly FPV drones with a low-latency long-range RC link
- build a custom 900 MHz or 2.4 GHz radio control link
- flash TX and RX hardware with high-performance RC firmware
- get long range control link for quadcopter racing
- replace stock RC link with open source LoRa-based system
- configure packet rates up to 1000 Hz with EdgeTX
When to choose
- you need maximum range and low latency for FPV or long-range flying
- you want an open source, community-maintained RC link with broad hardware support
- you fly with EdgeTX and want high packet rates
When to avoid
- you need a plug-and-play commercial link with vendor support and no flashing
- your use case is not radio control (e.g., general IoT telemetry)
- you require non-LoRa modulation or proprietary protocols
