• The Matrix 1S Brushless Flight Controller redefines 1S whoop performance of the 4IN1 version for analog mastery, adding built-in OSD and solder pads for external VTX, and this flight controller also features with a STM32G473 MCU for 55% faster processing—delivering effortless setup, pro-tier control, and uncompromised flight dynamics that rewrite 1S standards
• This Matrix 1S 4IN1 brushless flight controller comes with 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
• This Matrix 1S Whoop Flight Controller retains soldering pads for external analog VTX, giving pilots more options for image transmission flexibility. And the this Matrix 4IN1 1S flight controller also reserves 2 complete full-featured serial ports that can be used for external serial receivers, GPS, HD VTX, or other serial devices
• Unlike traditional shared power supply designs, the Matrix 1S FC features an independent 3.3V LDO power supply exclusively for the IMU. This innovation eliminates interference, creating a cleaner and more stable environment that enhances flight precision, improves sensitivity, and reduces the risk of performance issues—ensuring unmatched stability during every flight
• BETAFPV Matrix 4IN1 Brushles Flight Controller adopts the classic cross shape design with only 3.6g ultralight weight, reasonable layout, and easy to build. With a 25.5mm x 25.5mm mounting hole size, it is fully compatible for the whoop frame like the 65/75mm wheelbase racing whoop drones
