Description

The DarkMatter STACK 750 combines the BRAHMA F7 MK-I flight controller and VISHNU 50 MK-II ESC into a unified, high-reliability system. The flight controller leverages an STM32F7 processor for high-speed loop times and pairs it with an ICM42688P gyroscope for precise attitude sensing, supported by a DPS310 barometer for altitude hold functionality. The integrated AT7456E OSD provides clear, customizable telemetry overlay directly in your FPV feed.

The VISHNU 50 MK-II 4-in-1 ESC delivers robust 50A continuous current per motor, built to handle the high transient loads of aggressive freestyle and racing maneuvers on 3-6S power systems. The stack’s design includes reverse polarity, over-current, and over-voltage protection to safeguard components. Additional solder pads offer flexibility for direct ESC-to-FC wiring, catering to custom build requirements.

Key Features

  • BRAHMA F7 MK-I FC with STM32F7 processor for high-performance flight control and filtering.
  • VISHNU 50 MK-II 4-in-1 ESC with 50A continuous current rating per motor, supporting DShot and PWM protocols.
  • Advanced sensor suite including ICM42688P gyro/accelerometer and DPS310 barometric pressure sensor.
  • Integrated AT7456E OSD chip for Betaflight-configurable on-screen display.
  • 32MB Winbond flash memory for extensive Blackbox flight data logging.
  • USB Type-C port for reliable firmware updates and configuration.
  • Comprehensive electrical protection against reverse polarity, over-current, and over-voltage.
  • 30.5x30.5mm mounting footprint with 4mm holes for standard FPV frame compatibility.

Applications

  • High-performance 5-inch FPV racing drones requiring precise control and robust power delivery.
  • Aggressive 5-inch and 6-inch freestyle quadcopters built for 4S-6S LiPo power systems.
  • Custom FPV builds utilizing a 30.5x30.5mm stack mounting pattern for a clean, integrated power and control system.
  • Drones intended for advanced pilots leveraging Blackbox logging for tuning and performance analysis.

Frequently Asked Questions

What is the input voltage range for the DarkMatter STACK 750?

The STACK 750 is designed for 3-6S LiPo batteries, corresponding to an input voltage range of approximately 10V to 25.2V. Power can be supplied through the 8-pin connector between the FC and ESC or via the dedicated power pads on the bottom of the flight controller.

What flight control firmware is compatible with the BRAHMA F7 MK-I flight controller?

The BRAHMA F7 MK-I is natively configured for Betaflight, leveraging its STM32F7 processor for high-performance filtering and control rates. It is also compatible with other STM32-based firmware such as EmuFlight. The integrated AT7456E OSD chip is fully supported within Betaflight's OSD tab for telemetry configuration.

What motor protocols does the VISHNU 50 MK-II ESC support?

The VISHNU 50 MK-II ESC supports modern digital protocols including DShot (150, 300, 600, 1200) and traditional PWM. It is typically flashed with BLHeli_S or Bluejay firmware, which can be configured via the ESC configurator tool in Betaflight or through a dedicated suite like BLHeli Configurator.

What is the mounting pattern for this FC/ESC stack?

The DarkMatter STACK 750 uses a standard 30.5mm x 30.5mm mounting hole pattern with 4mm diameter holes. This is the most common footprint for FPV drone frames, ensuring compatibility with a wide range of 5-inch and larger multirotor builds.
