BAYCKRC 900MHz and 2.4GHz ELRS Dual Band Gemini RX Receiver with 2 Antennas for Drone

BAYCKRC Gemini RX (900MHz / 2.4GHz ELRS) from Phoenix drones is a compact, modern, and reliable receiver for FPV drones that combines operation in two frequency bands simultaneously. The device belongs to the category: Drones & Quadcopters > Receivers and is designed for pilots who require maximum stability and versatility in challenging flight conditions.

The receiver supports five operating modes, allowing flexible signal reception configuration for specific tasks and terrain conditions:

• 900MHz Diversity
• 900MHz Gemini
• 2.4GHz Diversity
• 2.4GHz Gemini
• 900MHz & 2.4GHz Gemini (Xrossband)

The module is based on two LR1121 chips, ensuring reliable reception and operation in diversity/dual mode. An ESP32 PICO is used as the main controller, and an integrated TCXO is applied for frequency stability across various temperature ranges. Connection to the flight controller is via the CRSF/UART interface, and configuration and management are performed using a convenient WebUI over Wi-Fi.

Key Technical Specifications and Advantages

• Dual-band architecture: supports 900 MHz and 2.4 GHz separately or simultaneously for enhanced communication reliability.
• ELRS protocol support: minimal latency, high channel refresh rate, and communication stability.
• Two LR1121 chips provide high-sensitivity reception and diversity mode capability.
• ESP32 PICO as a controller for fast updates and flexible configurations.
• Integrated TCXO guarantees accuracy and stable operation during sharp temperature changes.
• Telemetry power up to 100 mW for a reliable return channel and better data exchange.
• Compact size and standard connectors for easy integration into various drone configurations.

How to Use the Receiver

• 1. Connect the receiver to the flight controller via CRSF (UART).
• 2. Connect both IPEX-1 dual-band antennas (T-antennas) for optimal coverage.
• 3. For initial setup, connect to the WebUI via Wi-Fi: select reception mode, update firmware, or check device status.
• 4. After binding to the transmitter, choose the frequency and parameters depending on flight conditions and tasks.
