Product detailed description

FC HDZero Halo (ICM42688 version)

The HDZero Halo (ICM42688 Version) is a compact, ultra-performance flight controller built around the powerful STM32H743 MCU and designed specifically for modern digital FPV. With a built-in true diversity ExpressLRS Gemini receiver, TXCO-stabilized signal performance, and optimized stacking for the HDZero Race v3 VTX, the Halo delivers unmatched link reliability, clean wiring, and a race-ready low-profile build.

Features:
- Powerful H743 processor for fast, smooth flight performance.
- ICM42688 gyro for precise control and clean tuning.
- Built-in ELRS Gemini receiver with true diversity for the most stable 2.4GHz link.
- TXCO module keeps the receiver stable even in high heat.
- Perfect for HDZero – designed to stack tightly with the HDZero Race v3 VTX.
- Solderless design with plug-in ESC and VTX ports for quick builds and fast field repairs.
- Strong BEC outputs: 5V/4A, 9V/3A, 4.5V/0.5A for powering VTX, LEDs, and accessories.
- 16MB Blackbox for easy tuning and flight log analysis.
- Supports serial & parallel LEDs for clean lighting setups.
- USB Type-C for easy configuration.
- 20x20 mounting with grommets, compact and race-ready.
- Supports 3S–8S power input.
