Built on the ExpressLRS system, it delivers fast response times and an ultra-long range that can adapt as your setup grows, while remaining straightforward to install and update.

What makes ER8 stand out:

  • 8 PWM channels to drive multiple servos with precision
  • Built-in receiver voltage telemetry with automatic input recognition for convenience
  • High-sensitivity 20 cm dual antennas for improved link stability
  • 4-pin CRSF interface supports future telemetry sensor expansion
  • Wi‑Fi updates and WEBUI configuration streamline setup and upgrades

Designed for real-world use

ER8 is purpose-built for fixed-wing aircraft, offering robust mechanical strength with a one-piece molded shell. Its compact 43×30×15 mm form fits a variety of airframes without sacrificing performance. The device supports 8 channels and can automatically detect the appropriate voltage input, reducing wiring complexity in field setups.

  • Dual-antenna design enables better reception in challenging environments
  • Telemetry power can be tuned up to 100 mW for enhanced data visibility without overloading the system
  • Built-in voltage telemetry helps you monitor power while in flight

Compatibility and future-proofing

ER8 works with all 2.4GHz ExpressLRS modules and transmitters, making it a flexible upgrade for existing ELRS fleets. It supports easy updates via Wi‑Fi and can be configured through a WEBUI, helping you tailor the setup to your airframe and preferences.

Whether you fly sport airplanes or more advanced fixed-wing configurations, the ER8 provides a solid balance of range, responsiveness, and telemetry, all in a compact, durable design. Consider it as a capable building block for your ELRS-enabled cockpit without overhauling your current hardware.
