Flight controller Matrix 1S ​​Brushless Flight Controller (5in1 II)

The Matrix 1S ​​5IN1 II is an ultra-lightweight, next-generation all-in-one (AIO) flight controller designed specifically for 1S whoops. This version received a significant upgrade in power and reliability. The main feature is the integration of five components on one board: flight controller (FC), speed controller (ESC), on-screen display (OSD), Serial ELRS 2.4GHz receiver and video transmitter (VTX) with a power of up to 400 mW.

Specifications

Flight Controller (FC)

Processor: Powerful STM32G473CEU6, providing high processing speed for complex maneuvers.

Gyro: ICM42688P (supported in Betaflight 4.5.3 and above).

Blackbox memory: 16 MB for recording flight logs.

Power (BEC): 5V with a maximum current of 3A.

Interfaces: 4 full UART ports. By default, UART2 is allocated to VTX, and UART3 is allocated to the built-in RX.

USB Port: Extended via SH1.0-4Pin adapter to save weight.

Fastening: Standard 26x26mm holes with innovative 3-point fixation system for better shock absorption.

Speed Controller (ESC)

Constant current: 12A (a significant improvement over previous 5A versions).

Peak current: Up to 18A.

Firmware: Bluejay (A_X_5_96KHz), supporting RPM filtering and PWM frequency up to 96 kHz.

Protocols: DShot300 and DShot600.

Feature: Using 12 MOS tubes and JST1.25 gold plated connectors for maximum conductivity.

Video transmitter (VTX) and receiver (RX)

VTX: operates at 5.8 GHz (48 channels), has adjustable power (Pit/25/100/200/400 mW). Supports SmartAudio 2.0.

RX: Built-in Serial ExpressLRS 2.4GHz (CRSF protocol). Firmware version V3.4.3, which can be updated via Wi-Fi or Betaflight Passthrough.

Design Features

Increased Durability: The board has a thickness of 1.0mm (instead of the standard 0.8mm) and optimized component layout, making it resistant to hard crashes.

3-Point Mounting System: Creates additional space for shock absorption, reducing the risk of damage to electronics by 80%.

Variability: The model is available in Solder-free version (with already soldered motor connectors and BT2.0 power cable) and Solder-required (for those who want to save weight and solder wires directly).

Weight: Only 4.1g for the solderless version and approximately 3.76g for the soldered version.

Equipment (Solder-free Version)

The standard delivery package includes the following items:

Matrix 1S 5IN1 II flight controller (plug-in version).

Type-C to SH1.0 adapter for connecting to a computer.

Adapter cable SH1.0-4Pin.

Linear 5.8G antenna for video transmitter.

Set of screws for fastening: 4 pcs. M1.24 and 4 pcs. M1.45 (screws).

Rubber shock absorbers (4 pcs.) to reduce vibrations from the gyroscope.
