Core Features & Benefits
1. 915MHz Band for Superior Long-Range & Penetration
Operating on the 915MHz industrial ISM band, it delivers better signal diffraction and obstacle penetration than common 2.4GHz RC systems, with longer transmission range and stronger anti-blocking performance. It is ideal for long-distance RC flight in open outdoor areas, greatly improving RC link stability and reducing signal loss risk.
2. Dual-Chip Architecture for Stable & Reliable Performance
Built with a professional SX1276 RF chip paired with an ESP8285 main controller, it features high-precision RF signal transceiving and strong weak-signal demodulation capability. The main controller runs ELRS firmware smoothly, balancing low-latency response and high receiving sensitivity, and maintains a stable RC connection even in complex outdoor electromagnetic environments.
3. 100mW Return Power for Stable Two-Way Telemetry
Equipped with a 100mW return link, it supports stable transmission of aircraft status data back to the remote controller, allowing real-time viewing of flight voltage, distance, signal quality and other telemetry information. Paired with a matching ELRS TX module, it enables ultra-long-range two-way data transmission to meet the long-distance control needs of long-range flight enthusiasts.
4. Wide Voltage Input for Strong Compatibility
It supports a wide DC input range of 3.6V-4.2V, powered directly by a 1S LiPo battery. It fits the common power system of RC model equipment, requiring no extra step-up/step-down modules. The simple wiring and easy installation effectively reduce overall wiring complexity and extra payload.
5. Open-Source ELRS Protocol with Wide Compatibility & Flexibility
Developed based on the standard ExpressLRS open-source protocol, it is compatible with most ELRS-supported remote controllers and TX modules on the market. It supports online firmware updates and custom parameter configuration, allowing users to adjust refresh rate, power and other settings according to flight needs for flexible usage across different scenarios.
6. Compact & Lightweight Design for Easy Installation
The compact and lightweight body adds minimal payload to the aircraft. With standard connection terminals and mounting positions, it fits the installation space of most FPV drones and fixed-wing airframes, making assembly and wiring simple and easy even for beginners.
