The ER12 is designed for larger aircraft that require a higher channel count and robust power handling without unnecessary complexity. Its full-size layout and straightforward integration make it well suited to multi-servo, higher-current installations.
Features
ExpressLRS Performance: Low latency, high reliability, and excellent link quality with flexible configuration options.
Dual-Band Gemini-X RF System (2.4GHz + Sub-G 900MHz): Utilizes both frequency bands to provide enhanced link reliability across a wide range of operating environments.
12 PWM Outputs + Serial Support: Full 12-channel PWM output with dedicated bidirectional UART and serial interfaces for system integration and expansion.
XT30 Dedicated Power Input: Provides stable, high-current power delivery for demanding servo systems and larger aircraft installations.
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 three power sources simultaneously using dedicated ADC channels: EXT-V (up to 70V), receiver supply voltage (V-PWM) (up to 12V), and XT30 input voltage (up to 12V).
External UART Port: Dedicated interface for telemetry, external devices, and system expansion.
Wi-Fi Updates & WebUI: Configure settings and perform firmware updates wirelessly without disassembly.
Robust MMCX Antenna Connectors: Secure, serviceable antenna connections for easy maintenance and long-term reliability.
Durable Injection-Molded Housing: Provides consistent protection and structural durability for demanding installations.
Application: Designed as a PWM receiver for large fixed-wing aircraft, especially where multiple servos and higher current loads are involved.
Compatibility: Compatible with all ExpressLRS transmitters and modules, including radios with built-in ELRS.
Built on the ExpressLRS platform and equipped with dual Semtech LR1121 transceivers, the ER12 utilizes a dual-band Gemini X RF architecture operating on both 2.4 GHz and Sub-G 900 MHz. The result is a stable, consistent control link across a wide range of operating environments, with an architecture that prioritizes dependable operation.
