Betafpv Matrix 1S Brushless Flight Controller (3IN1/4IN1)
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.
Betafpv Matrix 1S Brushless Flight Controller (5IN1 II)
The Matrix 1S 5IN1 II Brushless Flight Controller is the next-generation flight controller engineered for pilots who refuse to compromise. Building on the proven all-in-one design, it delivers a substantial leap in both performance and durability. Experience the raw power of a 12A continuous ESC, the crash-proof confidence of 3-point mounting, and the build flexibility of Plug & Play or DIY versions. This is the durable, high-output core for your most demanding 1S whoop builds.
