The ER12 is designed for larger fixed-wing 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. Note on FCC Certification: Due to current FCC regulations classifying this product as a foreign-produced UAS component, we are currently unable to obtain FCC certification. This item cannot be shipped to or sold in the United States at this time. Please note this is the pre-order; Orders start shipping at the end of September. 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-Mo
