HDZero Halo Mini Flight Controller With ELRS Gemini RX
The HDZero Halo is a compact, high-performance flight controller powered by the H743 MCU, delivering robust computational capabilities for demanding FPV applications. It integrates a true diversity ExpressLRS (ELRS) receiver, supporting Gemini mode, which utilizes two receivers on two frequencies to significantly enhance ELRS reception. This advanced feature ensures superior link stability, making it a top choice for competitive pilots. To further enhance reliability, the Halo Flight Controller features a TXCO (Temperature Control Crystal Oscillator), ensuring consistent ELRS RX performance even in high-heat environments. This level of precision is crucial for maintaining a stable connection in extreme conditions. The integrated ELRS RX not only simplifies quad assembly but also provides a cost-effective solution. With the Gemini ELRS RX typically priced at $25, and the flight controller priced at $65, this combination represents significant savings compared to purchasing separate ELRS receivers and flight controllers. Additionally, the Halo Flight Controller includes a switchable 9V/3A BEC output for video transmitters, alongside a 5V/4A output for LED strips and other peripherals. Its design streamlines LED strip wiring, making it easy to connect parallel LED strips for uniform single-color illumination while simplifying the routing of addressable LEDs. Built for digital video systems, the Halo eliminates the analog OSD chip to reduce costs and save space. It is specifically designed to allow the HDZero Race v3 VTX to stack on top of it in a low-profile manner, resulting in a durable and compact stack height. This optimization ensures a secure, space-efficient build while maintaining excellent performance. The solderless design features dedicated ESC connection sockets (with an included 4A-rated cable) and easy connectivity for digital VTXes, allowing for quick swaps and hassle-free assembly in the field. With its Gemini mode support, TXCO-enhanced ELRS reception, low-profile HDZero Race v3 VTX stacking, and cost efficiency, the HDZero Halo is the ultimate flight controller for FPV racers and freestyle pilots seeking top-tier performance, reliability, and a sleek, durable build. The Halo Flight Controller is available in two versions, MPU6000 and ICM42688, to meet different pilot preferences.
