BETAFPV Matrix 3IN11S Brushless Flight Controller HD

The Matrix 1S Brushless Flight Controller redefines 1S whoop performance with two purpose-driven architectures: the 3IN1 for DJI O4 digital dominance (integrating FC, ESC, and ELRS 2.4G RX while omitting analog OSD), and the 4IN1 for analog mastery (adding built-in OSD + solder pads for external VTXs). Both feature the iconic cross-design architecture, newly developed BEC, 18A peak ESCs, and the STM32G473 MCU for 55% faster processing—delivering effortless setup, pro-tier control, and uncompromised flight dynamics that rewrite 1S standards. Attention Crafted for newcomers and recreational pilots, the Matrix FC features a robust 1mm board for enhanced durability, a solder-free design for easy installation, and a beginner-friendly experience. For advanced pilots, the ultra-thin and lightweight Air FC is the definitive choice, engineered with race-winning agility to push the boundaries of FPV flight performance. Flight controllers are covered for manufacturer defects. Issues arising from user errors, physical crash damage, damage during installation or dismantling, modifications, power surges, electrical fires, or water exposure are not covered. 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.
