Description

The BLITZ F745 Stack is engineered for demanding FPV racing and freestyle applications, combining a robust flight controller and a high-current ESC into a single, compact unit. The STM32F745 microcontroller offers ample processing power for complex flight algorithms, while the ICM42688-P gyroscope ensures low-noise, high-fidelity attitude data. An integrated LC filter on the flight controller minimizes electrical noise from the power system, contributing to cleaner video transmission and more stable flight performance.

The accompanying E55 4-in-1 ESC utilizes BLHeli_32 firmware, providing smooth motor control, advanced telemetry, and robust protection features like active braking and temperature monitoring. The stack’s design prioritizes ease of installation, with a dedicated connector for DJI Digital HD systems eliminating the need for soldering the VTX power and data lines. This stack is an ideal foundation for high-performance 5-inch and larger quadcopters operating on 4S to 6S battery packs.

Key Features

  • Advanced Flight Controller: STM32F745 MCU paired with a high-performance ICM42688-P gyroscope for ultra-responsive and stable flight handling.
  • High-Current ESC: 4-in-1 ESC rated for 55A continuous current per motor with 65A burst capability, powered by BLHeli_32 firmware.
  • DJI HD Integration: Dedicated plug-and-play connector for seamless, solder-free installation of DJI Air Units and Vista systems.
  • Extensive Data Logging: Equipped with 32MB of onboard flash memory for detailed Blackbox flight data recording.
  • Precision Barometer: Integrated DPS310 barometric sensor enables accurate altitude hold and variometer functions.
  • Expanded Connectivity: Six UART ports allow for simultaneous connection of GPS, telemetry, RC receivers, and other peripherals.
  • Clean Power Design: Onboard LC filter and dual BEC outputs (5V 2.5A & 9V 2A) ensure stable power for sensitive onboard electronics.
  • Comprehensive Control: Supports SmartAudio and IRC Tramp for VTX control, plus dedicated pads for programmable LEDs and a beeper.

Applications

  • High-performance 5-inch FPV racing drones requiring robust 4-in-1 ESC power and advanced flight control.
  • 6S-powered freestyle quadcopters where smooth BLHeli_32 motor control and extensive Blackbox logging are essential.
  • Builds utilizing the DJI Digital FPV System (Air Unit or Vista) seeking a clean, integrated stack solution.
  • Advanced long-range or cinematic drones requiring multiple peripherals like GPS, telemetry radios, and LED controllers.

Frequently Asked Questions

What is the maximum input voltage for the BLITZ E55 4-in-1 ESC?

The E55 ESC is rated for 2-6S LiPo battery input, which corresponds to a voltage range of approximately 7.4V (2S) to 25.2V (6S). Do not exceed 6S (25.2V) as this may damage the ESC and void the warranty.

How do I connect a DJI Air Unit or Vista to this stack?

The stack includes a dedicated plug-and-play connector for DJI HD systems. Simply connect the Air Unit or Vista's main power/data cable to this connector on the flight controller. No soldering is required for VTX power, ground, or SmartAudio data lines.

What Betaflight target should I use for the BLITZ F745 flight controller?

You should use the 'IFLIGHT_BLITZ_F7_AIO' target when flashing Betaflight firmware via the Betaflight Configurator. This ensures all gyro, barometer, and resource mappings are correctly configured for this specific board.

Can I use this stack with analog FPV systems?

Yes. While it has a dedicated DJI digital connector, the stack is fully compatible with analog VTXs. You would power the analog VTX from an available BEC (5V or 9V) and connect the video signal wire to a dedicated video pad on the flight controller. VTX control (SmartAudio/Tramp) is available via a dedicated pad.
