Description

I'm selling a brand new, sealed RadioMaster ER3 Pro ExpressLRS Gemini-X PWM receiver. I bought this for a build but never opened it — the box is still shrink-wrapped and in flawless condition. It’s compatible with ExpressLRS systems and suitable for drones and RC models that require a compact, high-performance receiver. Packed as new and ready to use.

The ER3 PRO is a compact receiver designed for installations where space is limited but link reliability and system access remain important. Despite its small footprint, it retains a full-featured RF and telemetry interface, making it well suited for clean, space-constrained builds.

Features
ExpressLRS Performance: Low latency, high reliability, and excellent link quality with flexible configuration options.
Dual-Band Gemini X (2.4GHz + Sub-G 900MHz): Utilizes both frequency bands to provide enhanced link reliability across a wide range of operating environments.
Up to 100mW Telemetry Output: Increased telemetry output power for improved data reliability and range.
3 PWM Outputs + Serial Support: Compact PWM output with CRSF and SBUS options.
External UART Port (Locking Connector): Dedicated interface for telemetry, external devices, and system expansion.
Independent Multi-Source Voltage Telemetry: Monitor up to two power sources simultaneously using dedicated ADC channels: EXT-V (up to 70V), receiver supply voltage (V-PWM) (up to 12V).
MMCX Antenna Connectors: Durable, replaceable antennas with a secure connection.
Wi-Fi Updates & WebUI: Configure and update directly without disassembly.
Durable Injection-Molded Housing: Compact, protective enclosure for long-term reliability.
Application: A compact, full-featured receiver for models that require advanced RF performance, telemetry, and connectivity in a space-efficient package.
Compatibility: Compatible with all ExpressLRS transmitters and modules, including radios with built-in ELRS.
