HDZero Halo Mini Flight Controller – H7 with Integrated Gemini ELRS

The HDZero Halo Mini Flight Controller delivers full-sized performance in a compact 20×20mm form factor. Powered by the STM32H743 (480MHz) with an ICM42688 gyro, it's built for pilots who demand precision and reliability without the bulk.

The integrated Gemini true diversity ELRS receiver runs two independent receivers on two frequencies simultaneously for rock-solid link stability — no separate RX needed. A TXCO (Temperature-Compensated Crystal Oscillator) keeps ELRS performance consistent even in high-heat race conditions.

Key Features:

• STM32H743 processor with ICM42688 gyro
• Integrated Gemini 2.4GHz ELRS receiver with true diversity
• Solderless design — dedicated sockets for ESC and HDZero/digital VTX connections
• Switchable 9V/3A BEC for VTX and 5V/4A BEC for LEDs and peripherals
• Supports parallel and serial LED strips for easy lighting setups
• Optimized for low-profile stacking with the HDZero Race V3 VTX
• 3S–8S compatible | 16MB onboard black box | USB-C
• Betaflight firmware target: HDZERO_HALO
