Description

The DarkMatter STACK 450 is a professional-grade FC/ESC combo designed for high-performance FPV racing and freestyle drones. The BRAHMA F4 MK-III flight controller serves as the central processing unit, leveraging an STM32F405 MCU and a Bosch BMI270 IMU for rapid, accurate flight calculations and stabilization.

Paired with the VISHNU 50 MK-II 4-in-1 ESC, this stack delivers robust 50A continuous current per motor, capable of handling aggressive 3-6S LiPo power systems. The integrated design simplifies wiring, reduces weight, and enhances reliability for competitive and demanding aerial applications.

Key Features

  • High-performance STM32F405 microcontroller with ample processing headroom.
  • Bosch BMI270 6-axis gyro/accelerometer and Infineon Technologies DPS310 barometer for precise altitude hold and acro performance.
  • Dual switching BECs provide clean 5V (2A) and 9V (2A) power for VTX, camera, and receiver systems.
  • Comprehensive connectivity with 4 UARTs and 1 I2C port for GPS, telemetry, and peripherals.
  • Onboard AT7456 OSD chip for real-time flight data overlay directly in your FPV feed.
  • 32MB Winbond flash for extensive Blackbox flight data logging.
  • Modern USB Type-C port for reliable firmware updates and configuration.
  • Supports up to 8 motors, enabling complex multirotor configurations like octocopters.

Applications

  • High-performance 5-inch and 7-inch FPV racing drones requiring a reliable, integrated FC/ESC stack.
  • Freestyle quadcopters where clean power delivery and robust Blackbox logging are essential for tuning.
  • Advanced multirotor builds, including hexacopters and octocopters, leveraging its 8-motor support.
  • Long-range or autonomous drone platforms utilizing its multiple UARTs for GPS, telemetry, and companion computers.
  • Drones operating in variable atmospheric conditions benefiting from the integrated barometer for altitude hold.

Frequently Asked Questions

What is the input voltage range for the DarkMatter STACK 450?

The STACK 450 is designed for 3-6S LiPo batteries, accepting an input voltage range from approximately 10V to 25.2V. Power is supplied through the G/V pins on the 8-pin connector or the dedicated pads on the bottom of the board.

How many UARTs are available on the BRAHMA F4 MK-III flight controller?

The flight controller provides four UART serial communication ports and one I2C port. This allows for extensive peripheral connectivity, such as GPS modules, telemetry radios, VTX control, and serial-based receivers like ExpressLRS or Crossfire.

What firmware is compatible with this FC/ESC stack?

The BRAHMA F4 MK-III flight controller is compatible with Betaflight and other STM32F4-targeted firmware. The VISHNU 50 MK-II ESC likely runs BLHeli_S or a similar ESC firmware, which can be configured via the flight controller's passthrough feature in Betaflight Configurator.

Does this stack support Blackbox flight data logging?

Yes, it includes a 32MB Winbond flash chip dedicated to Blackbox logging. This allows pilots to record high-rate gyro, motor, and RC data for detailed post-flight analysis and precise PID tuning to optimize flight performance.
