Stack HDZero Halo H743 ICM42688 70A AM32

Product detailed description

Stack HDZero Halo H743 ICM42688 70A AM32

The HDZero Halo H743 ELRS Stack (ICM42688 + 70A AM32 ESC) is a premium digital-ready FPV powertrain designed for high-performance racing and freestyle builds. Combining the Halo H743 flight controller with the Halo 70A AM32 4-in-1 ESC, this stack delivers exceptional response, clean power delivery, and an ultra-stable control link thanks to the integrated Gemini true-diversity ELRS receiver.

With the high-precision ICM42688 gyro, robust AM32 firmware, and plug-and-play connectivity for HDZero VTX systems, the Halo Stack provides professional-grade performance while simplifying the build process. The split-board architecture, heavy copper layers, and conformal coating make it durable, thermally stable, and race-ready out of the box.

Features: 
- ICM42688 high-precision gyro for smooth, low-noise flight tuning
- Integrated Gemini ELRS (true diversity) for unmatched link stability
- H743 480MHz processor for ultra-fast flight performance
- Plug-and-play design — easy connection to HDZero VTX, ESC, and RX
- 70A AM32 ESC with powerful burst capability up to 100A
- Split-board architecture with copper bus bar for clean, stable power
- Conformal-coated electronics for dust, moisture & corrosion protection
- Dual-sided motor pads for easier wiring and maintenance
- Optimized for 20×20 builds with minimal stack height
