Matrix 1S Brushed Flight Controller G4 4n1 V1.1

Bullet Points

• Dual DNA: 3IN1 (FC, ESC, and ELRS 2.4G RX) for DJI O4 digital dominance (omits analog OSD), 4IN1 for analog mastery with OSD.
• STM32G473 MCU: 55% faster processing than F411 for responsive tuning.
• Stable Video Transmission: Features a newly developed BEC to ensure consistent power delivery for seamless HD performance.
• Enhanced Overcurrent Capacity: Supports 12A continuous current and 18A peak ESC, providing robust performance for demanding flights.
• Reliable Precision: Includes an independent 3.3V LDO design to deliver stable, interference-free power directly to the IMU for accurate control.
• Whoop-ready Installation: The 3IN1 is equipped with motor plugs and a SH1.0-6Pin HD digital port for a hassle-free installation and maintenance experience, while the 4IN1 has external VTX soldering pads for protocol flexibility.
