About ExpressLRS/ExpressLRS-Hardware
ExpressLRS Hardware is an open-source collection of PCB designs, schematics, and 3D-printable enclosures for building ExpressLRS transmitter and receiver modules. ExpressLRS is a long-range radio control system designed for remote-controlled applications like drones, quadcopters, fixed-wing planes, and other RC vehicles. The project provides hardware blueprints that work with various microcontroller platforms including ESP32, ESP8266, and STM32 chips, along with LoRa modules like the SX127x and SX1280 transceivers.
The hardware designs enable enthusiasts and builders to construct their own TX and RX modules for reliable, high-performance remote control at extended ranges. The project is maintained by ExpressLRS LLC and an active open-source community focused on advancing FPV (first-person view) and RC technology. Users can either fabricate the PCBs professionally or 3D-print the cases themselves, making the system accessible to DIY builders at various skill levels.
The project emphasizes that users are responsible for ensuring compliance with local regulations regarding radio device operation, as requirements vary significantly by country. The developers provide experimental hardware designs without guarantees of stability or reliability, making this a community-driven effort for those willing to engage with emerging RC technology on their own terms.
