Description

The BLITZ Mini F745 Stack is engineered for high-performance mini and micro FPV drones requiring robust processing and power delivery. The flight controller’s STM32F745 MCU provides ample computational headroom for advanced flight algorithms, while the ICM42688 gyro ensures low-noise, high-fidelity angular rate data for precise stabilization.

Paired with the E55 Mini 4-in-1 ESC, the stack delivers 55A continuous current per motor with BLHeli_32 firmware, supporting high-rpm brushless motors on 2-6S battery configurations. The integrated 5V/2.5A BEC powers peripherals reliably, and the built-in DJI HD plug-and-play connector simplifies digital FPV system integration.

Key Features

  • High-Performance Flight Core: STM32F745 microcontroller paired with an ICM42688 gyroscope and DPS310 barometer for responsive, stable flight control.
  • Robust Power Management: Integrated 4-in-1 ESC handles 55A continuous (65A burst) per motor with BLHeli_32 firmware, compatible with 2-6S LiPo batteries.
  • Compact & Lightweight Design: 20x20mm mounting pattern with a total stack weight under 17g, ideal for weight-sensitive micro and mini quad builds.
  • Comprehensive Connectivity: Features 6 UARTs, SmartAudio/IRC Tramp VTX control, and a dedicated connector for DJI Digital HD FPV Air Units.
  • Advanced Flight Data Logging: Onboard 16MB flash memory for detailed Blackbox logging to fine-tune PID loops and filters.
  • Multi-Firmware Support: Pre-configured for Betaflight with target IFLIGHT_BLITZ_F7_AIO, also compatible with INAV and ArduPilot for autonomous flight.

Applications

  • High-performance 3-inch and 4-inch micro FPV racing and freestyle drones.
  • Compact long-range or cinematic mini quadcopters requiring stable altitude hold and navigation.
  • Lightweight build projects where a 20x20mm stack is mandated by the frame design.
  • Digital HD FPV builds utilizing the DJI FPV System for integrated video transmission.

Frequently Asked Questions

What is the input voltage range for the BLITZ Mini E55 ESC?

The integrated 4-in-1 ESC supports a wide input voltage range from 2S to 6S LiPo batteries (approximately 7.4V to 25.2V). This makes it suitable for a variety of builds, from lightweight 2S micro drones to high-power 6S mini quadcopters.

Is the flight controller compatible with ArduPilot or INAV?

Yes. While pre-configured with the Betaflight target IFLIGHT_BLITZ_F7_AIO, the STM32F745-based flight controller is fully compatible with INAV and ArduPilot firmware. You will need to flash the appropriate firmware and configure the ports and sensors for your autonomous flight application.

Does this stack include a built-in Video Transmitter (VTX)?

No, this stack does not include an integrated analog VTX. However, it features a dedicated plug-and-play connector for DJI Digital HD FPV Air Units, simplifying wiring for digital video systems. For analog VTX, you would use one of the available UARTs with SmartAudio/IRC Tramp for control.

What is the physical mounting pattern and weight of the stack?

The stack uses a compact 20x20mm mounting pattern with M2 screws. The flight controller weighs 4.8g and the ESC weighs 11.3g, resulting in a total stack weight of approximately 16.1g, not including connectors or wiring harnesses.
