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.

Note: Due to the shortage of IMU chip ICM42688, BETAFPV team has found new IMU chips including ICM42622, BMI270, and LSM6DSK320X, and built compatible firmwares. Extensive testing confirms they all meet our strict quality standards.

Betaflight has not yet released official firmwares compatible with some of the IMU chips, so please do not flash the official Betaflight firmware and pay attention to future support updates.

FEATURES

• All-in-One Integration: Combines the FC, ESC, OSD, Serial ELRS 2.4GHz RX, and a 5.8GHz 400mW VTX into a single, compact unit.
• Upgraded 12A Continuous ESC: Delivers 12A continuous current (18A peak) for powerful propulsion.
• Enhanced Durability: Features a robust 3-point mounting system and a 1.0mm thick PCB to absorb crash impacts and protect core components.
• Flexible Build Options: Available in both Solder-free and Solder-required versions to suit any skill level or weight preference. Features larger solder pads for easier, more reliable custom wiring.
• Advanced Core Components: Built around a powerful G473 processor for precise racing and complex freestyle maneuvers.
• Optimized Layout: A refined component arrangement improves durability and overall reliability.

Bluejay ESC Firmware

With BB51 ESC solution, Matrix 1S Brushless Flight Controller is based on A_X_5_96KHz_V0.19.hex for BB51 Bluejay hardware, it supports D-shot300, D-shot600, and even RPM filtering in Betaflight, offers 24KHz, 48KHz, and 96KHz fixed PWM frequency for options, and custom start-up melodies. 

DO NOT flash the firmware with a shorter interval, otherwise, there will be a certain chance of stalling and burning the flight controller.

Serial ELRS 2.4G RX

Serial ELRS 2.4G RX uses the Crossfire serial protocol (CRSF protocol) to communicate between the receiver and the flight controller board. So the Serial ELRS 2.4G RX is available to support upgrading to ELRS V3.0 with no need to flash Betaflight flight controller firmware. Enter binding status by power on/off three times.

• Plugin and unplug the flight controller three times;
• Make sure the RX LED is doing a quick double blink, which indicates the receiver is in bind mode;
• Make sure the RF TX module or radio transmitter enters binding status, which sends out a binding pulse;
• If the receiver has a solid light, it's bound.

The Serial ELRS 2.4G RX can be updated via Wi-Fi or Betaflight serial passthrough. Here is the way to update the Serial ELRS 2.4G RX firmware through passthrough.

• Plug in your FC to your computer, connect to ExpressLRS Configurator instead of Betaflight Configurator;
• Choose target "BETAFPV 2.4GHz AIO RX";
• Flash using the BetaflightPassthrough option in ExpressLRS Configurator.
