Important

• The Matrix 1S Brushless Flight Controller is crafted for beginners and casual pilots, offering enhanced durability with its thicker board and no welding required—making it perfect for entry-level users. As a result, it is slightly heavier than the Air Brushless Flight Controller 5IN1 version. For advanced FPV pilots seeking a more responsive, race-oriented experience, the Air Brushless FC 5IN1 version is highly recommended. The Matrix 1S Brushless FC and Air Brushless FC 5IN1 Version have undergone rigorous testing and meet competition-grade standards.

• 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.
• VTX Power: Higher VTX power consumes more energy and generates more heat, reducing flight time. For better flight time in indoor scenarios, use 25~100mW power.
• VTX Antenna: Connect and install the image transmission antenna before powering on the flight control. Alternatively, set transmission power to 0 to avoid burnout.

Features

• Built Tough: The Matrix 1S Brushless FC features a robust 1mm-thick circuit board. While slightly heavier, this design enhances durability for everyday training. For advanced pilots, the Air Brushless FC 5IN1 Verion provides a lighter alternative.
• Simplified Installation: The Matrix 1S Brushless FC is a true all-in-one flight controller with integrated FC+VTX+OSD+ESC+RX, plus standard motor plugs, making setup and maintenance remarkably easy. Ideal for FPV beginners, this design requires no welding and ensures a smooth installation experience.
• Upgraded Performance: Upgraded with the G473 processor, the Matrix 1S Brushless FC achieves a remarkable 55% increase in computing speed over the F411, delivering swift response for precise racing and complex freestyle maneuvers.
• Premium Video Transmission: Equipped with a high-quality 5.8GHz VTX supporting up to 400mW, the Matrix 1S ensures stable, accurate transmission for both daily flying and competitive racing.

Comparison Between Matrix 1S, F4 1S 5A AIO & Air 5in1

The Matrix 1S Brushless FC is designed with beginners in mind, offering enhanced durability and performance compared to the original F4 1S 5A AIO FC. With a 1mm-thick board, it’s more rugged than the 0.8mm-thick F4 1S 5A AIO board, and its built-in motor plug simplifies installation, eliminating the need for welding. With the advanced G473 processor and 5IN1 configuration, including a 5.8GHz 400mW VTX, the Matrix 1S is a better choice for beginners. For advanced pilots seeking a extremely lightweight, race-focused experience, the Air Brushless FC 5IN1 version is the best choice.

Meteor75 Pro Now Powered By the Upgraded Matrix 1S Brushless FC

Starting November 20, the Meteor75 Pro will be upgraded with the Matrix 1S Brushless FC. This enhancement introduces a durable 1mm-thick board, a high-speed G473 processor with a 55% boost in computing power, and an integrated 5.8GHz 400mW VTX. Built-in motor plugs simplify installation, making it more beginner-friendly. These advancements deliver improved durability and performance while ensuring the Meteor75 Pro excels in both indoor and outdoor FPV racing and freestyle flying.

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.

Betaflight Firmware and CLI

Betaflight official developers recommend using version 42688 of the gyroscope, and many issues with ICM42688 have been fixed in version 4.5.0. Please learn more from version 4.5.0.

• FC firmware: Betaflight_4.5.0_BETAFPVG473, Download the firmware and CLI dump file
• Reference link: https://github.com/betaflight/betaflight/releases/tag/4.5.0

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.
