DakeFPV H743 Stack 70A

The DAKEFPV H743 Stack is built around the STM32H743VGT6 processor.² With a clock speed of 480MHz, it handles advanced filtering and high PID loop frequencies with ease, making it a perfect match for the modern BlueJay firmware running on the ESC.

The XM-MH-70A ESC is the star of the power system. While most stacks top out at 6S, this ESC is rated for 3-12S, utilizing high-voltage MOSFETs and a massive TVS diode to protect against the inductive voltage spikes common in large-motor setups.⁴ The 30.5mm mounting pattern makes it a standard fit for most frames, but its performance is anything but standard.

Key Performance Highlights:

• H7 Extreme Processing: The STM32H743VGT6 MCU allows for complex autonomous missions in ArduPilot or ultra-low latency filtering in Betaflight.

• 12S LiPo Ready: One of the few 30×30 stacks natively supporting up to 12S ($50V$+), ideal for high-voltage, low-current efficiency in large drones.

• Dual Gyro Fusion: Uses two ICM42688 sensors to average out vibration noise, providing a “locked-in” feel even on unoptimized frames.

• BlueJay High-Speed ESC: The 70A 4-in-1 ESC comes pre-flashed with BlueJay, supporting Bidirectional DShot for real-time RPM filtering and smoother motor response.

• Unrivaled I/O: Features 7 UARTs, a dedicated I2C bus for compasses, and 8 motor outputs, making it natively compatible with X8 Octocopter configurations.

• Dual Camera Switcher: Toggle between two different flight cameras via your transmitter—perfect for hybrid cinematic/FPV setups.
