About BETAFPV Matrix 1S Brushless Flight Controller:
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.

Description
FAQ
Enhanced Continuous 12A ESC
HD image transmission adds weight to 1S whoops, demanding stronger power and higher ESC overcurrent capacity. 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.
Faster Processing, Smoother Flight
Powered by STM32G473 MCU, delivering significantly faster response than F4 FCs. Improves PID loop accuracy and flight stability.
Ultra-Light 3.6g Design
Minimizes overall drone weight for improved agility and longer flight time. Perfect for whoop racing and freestyle.
Ultra-Low Voltage Support, Zero Blackouts
High-performance digital VTX requires consistent current, especially on 1S whoops where voltage can drop to 3.3V. Our advanced BEC is engineered to deliver a powerful 3A output even at ultra-low voltages down to 2.85V. This ensures a stable, flicker-free image transmission during critical low-battery moments, giving you the best chance to recover your drone safely.
Effortless Setup and Maintenance
The Matrix 1S 3IN1 HD FC is designed to maximize your flight time by minimizing setup hassle. Equipped with convenient motor plugs and a SH1.0-6Pin HD digital port, it allows for a completely solder-free installation and maintenance process. Now, you can focus more on enjoying high-definition flight experiences instead of dealing with complex tools.
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.
How to Use Serial Ports, Intergrated RX and VTX
UART3 is connected to the built-in serial ELRS RX. To release UART3, please remove the resistor. Additionally, this FC reserves 2 complete full-featured serial ports that can be used for external serial receivers, GPS, HD VTX, or other serial devices. You can refer to the picture below.
