Description

The BLITZ Mini ATF435 Stack is engineered for high-performance mini and micro drones, combining a robust flight controller with a powerful 4-in-1 ESC in a space-saving footprint. The AT32F435RGT7 microcontroller, paired with a BMI270 gyro and DPS310 barometer, delivers responsive, low-latency flight control suitable for racing and aggressive freestyle maneuvers.

Its integrated E55S ESC is built on a high-current PCB with low-ESR capacitors, supporting 2-6S LiPo batteries and advanced ESC protocols like DShot, MultiShot, and OneShot. The stack includes a 5V/2.5A BEC for peripheral power and features six UARTs, I2C pads, and SmartAudio/IRC Tramp support for comprehensive system integration.

Key Features

  • High-performance AT32F435RGT7 MCU with 16MB flash for complex flight firmware.
  • BMI270 gyroscope and DPS310 barometer provide stable, accurate flight data.
  • Integrated E55S 4-in-1 ESC handles 55A continuous and 65A burst current per motor.
  • Wide 2-6S LiPo input voltage range supports high-cell-count micro drone builds.
  • AT7456E OSD chip enables real-time, customizable on-screen telemetry overlay.
  • Supports DShot150/300/600, MultiShot, and OneShot ESC protocols via BLHeli_S or Bluejay firmware.
  • Six UARTs and I2C pads allow extensive peripheral connectivity (GPS, VTX, telemetry).
  • Compact, lightweight design reduces overall build weight and simplifies installation.

Applications

  • High-performance 3-inch to 5-inch micro and mini FPV racing drones.
  • Compact freestyle drones requiring a powerful, integrated FC/ESC stack.
  • Lightweight long-range micro builds utilizing 4S-6S LiPo batteries.
  • Betaflight or INAV-based drones needing multiple UARTs for GPS and HD video systems.

Frequently Asked Questions

What is the maximum input voltage for the BLITZ Mini ATF435 Stack?

The stack supports a wide input voltage range of 2-6S LiPo batteries, which corresponds to approximately 8.4V to 25.2V. The integrated E55S ESC and flight controller BEC are designed to handle this range, making it suitable for high-performance micro builds on 4S, 5S, or 6S power.

Which flight firmware is compatible with this stack?

The BLITZ Mini ATF435 Flight Controller is fully compatible with Betaflight and INAV firmware. Its AT32F435RGT7 MCU provides ample processing power and flash memory for the latest firmware features and tuning options, allowing for precise control in both racing and autonomous flight scenarios.

What ESC firmware does the E55S 4-in-1 ESC use, and can it be updated?

The ESC comes flashed with BLHeli_S firmware (version Q-H-25 16.7) and is also compatible with the Bluejay firmware (Q-H-50). You can update or configure the firmware using standard BLHeli Suite or Bluejay configurator tools via a standard 4-wire interface for features like bidirectional DShot and improved motor timing.

How many UARTs are available for peripherals?

The flight controller provides six UARTs and dedicated I2C pads, offering extensive connectivity for peripherals such as GPS modules, digital HD VTX systems (like DJI or Walksnail), telemetry radios, and LED strips. This makes the stack highly versatile for complex builds.
