Are you looking to buy RadioMaster ER16 PWM Dual-band Gemini & Gemini-X Receiver in Australia?

The ER16 is built for large-scale aircraft that demand redundancy, robust power handling, and reliable system integration. Designed with redundancy at every critical point—RF link, power input, and system control—it delivers a stable, high-integrity connection for complex fixed-wing platforms.

Features

ExpressLRS Performance: Low latency, high reliability, and excellent link quality with flexible configuration options.
Dual-Band Gemini X 2.4GHz and Sub-G 900MHz: Simultaneously operates on both frequency bands to maintain a stable RF link in challenging environments.
16 PWM Outputs + Serial Support: Full 16-channel PWM output with dedicated bidirectional UART and serial interfaces for system integration and expansion.
Dual XT30 Redundant Power Input (Isolated): Two isolated XT30 inputs support independent redundant power sources with separate telemetry reporting for each battery. If one power source fails, the system continues operating from the remaining supply without interruption.
External Safety Switch (SW Port): Dedicated interface for pull-tab or external safety modules, allowing the system to remain inactive until intentional power-up for safer handling and operation.
Top-Mounted Servo Outputs: PWM connections are positioned on the top side for cleaner wiring, easier access, and simplified installation.
PWM Signal Amplification: Amplified PWM outputs help maintain signal quality over long servo leads and extension cables. They also improve compatibility with larger, high-torque servos, helping ensure reliable control signal delivery throughout the aircraft.
Independent Multi-Source Voltage Telemetry: Monitor up to four power sources simultaneously using dedicated ADC channels: EXT-V (up to 70V), receiver supply voltage (V-PWM) (up to 12V), XT30-1 input voltage (up to 12V), and XT30-2 input voltage (up to 12V).
External Voltage Telemetry Connector: Dedicated connection for direct main-pack voltage monitoring.
External UART Port: Dedicated interface for telemetry devices, sensors, and system expansion.
Wi-Fi Updates & WebUI: Configure and update directly without disassembly.
Robust MMCX Antenna Connectors: Secure, serviceable antenna connections for easy maintenance and long-term reliability.
Durable Injection-Molded Housing: Designed for structural strength and consistent protection in large airframes.
Application: Designed as a PWM receiver for large fixed-wing aircraft, especially where redundancy and higher channel counts are required.
Compatibility: Compatible with all ExpressLRS transmitters and modules, including radios with built-in ELRS.

At its core is the ExpressLRS system, built around dual Semtech LR1121 transceivers and a dual-band Gemini X RF architecture operating on both 2.4 GHz and Sub-G 900 MHz. This delivers reliable control link performance across a wide range of operating conditions.

With 16 PWM outputs, serial protocol support, dedicated telemetry interfaces, an external safety system, and multi-channel voltage telemetry, the ER16 provides comprehensive monitoring and control of critical onboard systems. Independent telemetry channels support Batt 1, Batt 2, Ext-V, and additional sensor-reported voltage sources, providing complete visibility of redundant power systems throughout the aircraft.

The ER16 features amplified PWM outputs designed to maintain signal quality across long servo runs and extension cables often found in large-scale aircraft. The amplified output stage also improves compatibility with larger, high-torque servos, helping deliver reliable control signals throughout the aircraft. The receiver also features four independent voltage telemetry channels with dedicated ADCs, allowing simultaneous monitoring of the receiver supply voltage (V-PWM) (up to 12V), XT30-1 input (up to 12V), XT30-2 input (up to 12V), and an EXT-V input for monitoring external battery voltages up to 70V. The ER16 includes a dedicated 4-pin JST-GH locking UART/CRSF port for flight controllers, stabilisers, telemetry sensors, and other UART peripherals.

Dual isolated XT30 inputs allow independent power sources to operate in parallel without risk of backfeed. If one supply drops, the system continues operating seamlessly from the remaining source without switching or intervention.

From installation to operation, every detail is designed to simplify integration and improve serviceability, including top-mounted servo outputs for cleaner wiring, robust MMCX antenna connections, and a durable injection-molded housing built for long-term use.
