Description: 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 receivers). Both feature the iconic cross-design architecture, newly developed BEC, 18A peak ESCs, and the STM32G473 MCU for 55% faster processinga??delivering effortless setup, pro-tier control, and uncompromised flight dynamics that rewrite 1S standards. Feature: - 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 RX soldering pads for protocol flexibility.

To meet these challenges, an advanced BEC has been developed, capable of delivering over 3A of current at ultra-low voltages down to 2.85V. This ensures stable image transmission even in critical situations. While flying to such low voltages isn't recommended, this inovation provides pilots with a greater chance of safely recovering from unexpected situations. Enhanced Continuous 12A ESC Whether powering digital HD systems or high-performance analog builds, 1S whoops demand ESCs that wona??t flinch. Our engineers exceeded expectations, delivering a robust ESC with 12A continuous output and 18A peak capacity on the iconic "cross" flight controller. This ensures optimal thrust-to-weight ratio, reliable performance, and worry-free high-definition flights. Individual Power Supply for IMU Unlike traditional shared power supply designs, the Matrix 1S FC features an independent 3.3V LDO power supply exclusively for the IMU. This inovation eliminates interference, creating a cleaner and more stable environment that enhances flight precision, improves sensitivity, and reduces the risk of performance issuesa??ensuring unmatched stability during every flight. Whoop-ready Installation Equipped with convenient motor plugs and a SH1.0-6Pin HD digital port, the 3IN1 version allows for a completely solder-free installation and maintenance process. Spend less time building and more time flying HD whoops. The 4IN1 version retains soldering pads for external analog RX, giving you protocol freedom while reducing voltage ripple interference for cleaner video signals.
