The BetaFPV Matrix 1S Brushless Flight Controller reimagines 1S performance, offering two purpose-built architectures for different pilot needs: 3IN1 for the digital dominance of the DJI O4 and 4IN1 for mastery of analog systems. Both versions feature the iconic cross-shaped architecture, the latest BEC, an 18A peak current ESC, and an STM32G473 processor, 55% faster than the F411. This ensures easy setup, professional-level control, and uncompromising flight dynamics that set new standards for 1S drones.
This flight controller is the heart of your micro drone, guaranteeing exceptional stability and power even in the most demanding flight scenarios. Key Features:
General Features (for both versions):
Processor (MCU): STM32G473CEU6 (168 MHz) – 55% faster than the F411, providing extremely responsive tuning and performance.
Gyro: ICM42688P.
Blackbox Memory: 16 MB.
Sensors: Voltage and Current.
BEC (Benchtop ESC):
The newly developed BEC: Provides a stable 5V/3A power supply for smooth operation of HD systems, even with low battery voltage (down to 2.85V).
ESC (Electrospeed Controller):
Built-in ESC: 12A continuous current, 18A peak current ensures reliable performance even in challenging flights.
ESC Firmware: Bluejay based on BB51 (A_X_5_96_v0.19.2.hex).
Digital signal protocols: DSHOT300, DSHOT600.
Independent IMU power supply: Separate linear voltage regulation (3.3V LDO) for the IMU eliminates interference and improves control accuracy.
Battery connector: BT2.0.
Mounting size: 25.5 mm x 25.5 mm.
Motor connector: JST1.25-3Pin.
