Description

The RadioMaster ER6 receiver leverages the ExpressLRS protocol to provide a robust, low-latency control link for fixed-wing aircraft and gliders. Its optimized PCB design ensures stable signal processing and reliable servo PWM output across all six channels.

Engineered for operational flexibility, the ER6 automatically detects and reports voltage from either its internal BEC (4.5-8.4V) or an external flight pack (4.0-35V). The dedicated CRSF port allows for seamless integration of additional telemetry sensors, while the one-piece molded shell provides impact resistance and structural integrity for demanding flight environments.

Key Features

  • ExpressLRS 2.4GHz system offering high reliability and ultra-long range.
  • Dual-antenna design with telemetry power adjustable up to 100mW via LUA script.
  • Automatic voltage telemetry switching between receiver input and external battery.
  • High-quality 2.54mm pitch connectors for secure servo and telemetry wiring.
  • One-piece molded receiver shell for enhanced durability and vibration resistance.
  • WEBUI and Wi-Fi support for convenient firmware updates and configuration.
  • Compatible with all 2.4GHz ExpressLRS modules and integrated transmitter systems.

Applications

  • Primary receiver for fixed-wing RC airplanes requiring up to 6 servo channels.
  • Control link for gliders and sailplanes utilizing PWM-based flight surfaces.
  • Integration into scale model aircraft builds needing reliable voltage telemetry.
  • Base platform for expanded telemetry systems via the CRSF sensor port.

Frequently Asked Questions

What is the input voltage range for the RadioMaster ER6 receiver?

The ER6 operates on a DC input voltage range of 4.5V to 8.4V, typically supplied by a BEC from your ESC or a separate UBEC. Its built-in telemetry can also automatically detect and report an external flight battery voltage within a range of 4.0V to 35V.

How many servo channels does the ER6 support and what is its primary use case?

The ER6 provides 6 standard PWM output channels, making it specifically designed for fixed-wing aircraft and gliders that require direct servo control for ailerons, elevator, rudder, throttle, and auxiliary functions. It is optimized for models that do not require a flight controller with serial protocols.

Can I update the firmware on the ER6 receiver and how?

Yes, the ER6 supports firmware updates via Wi-Fi. You can connect to the receiver's built-in Wi-Fi access point and use a web browser (WEBUI) to upload new firmware files, allowing for easy updates and configuration changes without needing a physical data cable.

What is the purpose of the 4-pin CRSF port on the ER6?

The 4-pin CRSF port is an expansion interface that allows you to connect additional telemetry sensors (such as GPS, vario, or current sensors) to the receiver. This enables you to stream more detailed flight data back to your ExpressLRS-compatible transmitter or ground station.
