Description

The BLITZ ATF435 Stack is a compact, high-power solution for performance-oriented FPV builds. The flight controller’s AT32F435RGT7 processor, an ARM Cortex-M4 core, handles high-frequency PID loops, while the ICM42688 gyroscope provides precise angular rate data for responsive flight characteristics. The integrated E55S 4-in-1 ESC delivers 55A continuous current per motor with robust 2-6S LiPo compatibility, powered by BLHeli_S or Bluejay firmware for customizable motor control.

Structural integration is optimized with a direct stack design, reducing wiring complexity and improving signal integrity. The board includes a DPS310 barometer for accurate altitude hold, an AT7456E OSD chip for real-time telemetry overlay, and a 5V/2.5A & 9V/2A BEC for powering peripherals. Six UARTs offer extensive connectivity for GPS, telemetry receivers, and other serial devices, making it suitable for advanced racing drones and acrobatic freestyle platforms.

Key Features

  • High-Performance Flight Core: AT32F435RGT7 MCU (ARM Cortex-M4) paired with an ICM42688 gyro for low-latency, high-fidelity flight control.
  • Robust 4-in-1 ESC: 55A continuous current per motor with 65A burst, fully compatible with 2-6S LiPo battery configurations.
  • Advanced Sensor Suite: Integrated DPS310 barometer provides stable altitude data for autonomous flight modes.
  • Extensive Logging & Telemetry: 32MB onboard flash memory for Blackbox logging; AT7456E chip enables customizable OSD.
  • Versatile Connectivity: Six UART serial ports support GPS, telemetry radios, LED strips, and other peripherals.
  • Integrated Power Management: Dual BEC outputs (5V 2.5A & 9V 2A) reliably power FPV cameras, VTXs, and receivers.
  • Firmware Flexibility: ESC runs BLHeli_S firmware with optional Bluejay support for advanced motor timing and features.
  • Streamlined Build Design: Pre-configured wiring harness and stack mounting reduce assembly time and potential points of failure.

Applications

  • 5-inch high-performance FPV racing drones requiring stable control and high-current ESCs.
  • Freestyle quadcopters built for aggressive acrobatics and precise maneuvering on 4S-6S LiPo packs.
  • Advanced Betaflight setups utilizing extensive peripherals like GPS, telemetry modules, and LED strips.
  • Builds aiming for a clean, integrated stack layout to minimize wiring and reduce electromagnetic interference.

Frequently Asked Questions

What is the input voltage range for the BLITZ ATF435 Stack?

The integrated E55S 4-in-1 ESC supports a wide input voltage range from 2S to 6S LiPo batteries, corresponding to 7.4V to 25.2V. This makes it suitable for builds ranging from lightweight 4S racers to powerful 6S freestyle quads.

How many UARTs are available on the ATF435 flight controller?

The flight controller provides six (6) UART serial ports. This extensive connectivity allows you to simultaneously connect peripherals such as a GPS module, ExpressLRS or Crossfire receiver, SmartAudio/IRC Tramp VTX, telemetry radio, and LED strips without requiring softserial.

Can I flash Bluejay firmware onto the E55S 4-in-1 ESC?

Yes, the E55S ESC is compatible with both BLHeli_S and Bluejay firmware. Bluejay offers features like bidirectional DShot, improved motor startup, and customizable PWM frequency, which can be flashed using standard ESC configuration tools like the BLHeli_S Configurator.

What mounting pattern does this stack use?

The BLITZ ATF435 Stack uses the standard 30.5x30.5mm mounting pattern common to most 5-inch FPV drone frames. It is secured using M3 screws through the provided silicon grommets for vibration isolation.
