HDZero Halo Mini Flight Controller – High-Performance ELRS & Digital FPV Control The HDZero Halo Mini Flight Controller is a compact, high-performance FPV flight controller built for competitive drone racing and freestyle flying. Featuring the powerful STM32H743 MCU, it delivers fast processing speeds and precise control. Designed with integrated ExpressLRS (ELRS) Gemini mode, it utilizes dual receivers on separate frequencies for enhanced link stability, making it an ideal choice for pilots who demand top-tier signal reliability. To ensure consistent performance, the Halo Flight Controller incorporates a Temperature-Controlled Crystal Oscillator (TXCO) for stable ELRS RX performance, even in high-heat environments. This innovative design eliminates the need for an external ELRS receiver, providing a cost-effective and efficient solution for drone builders. Engineered for digital FPV systems, the Halo FC removes the analog OSD chip to save space and reduce costs. It is specifically optimized to stack seamlessly with the HDZero Race v3 VTX, ensuring a compact, low-profile build while maintaining maximum durability and performance. With solderless ESC connections, dedicated sockets for digital VTX systems, and powerful BEC outputs (9V/3A, 5V/4A), the HDZero Halo Mini Flight Controller is the perfect choice for FPV pilots looking for cutting-edge technology, reliability, and ease of installation.
