Introduction
The HDZero Halo is a compact flight controller powered by the H743 MCU for high-performance computation. It integrates a Gemini ELRS receiver and features a switchable 9V/3A BEC output for video transmitters, along with a 5V/4A output for LED strips and other peripherals. The integrated ELRS RX simplifies quad assembly and ensures high-performance link quality with its Gemini.
The Halo Flight Controller makes connecting parallel LED strips for single colors straightforward and simplifies the routing of addressable LED strip wires. Designed for digital video systems, it eliminates the analog OSD chip to save space and reduce costs. It's particularly optimized for use with the HDZero Race v3 VTX, ensuring a low-profile stack.
The Halo Flight Controller features dedicated sockets for connecting ESCs with a maximum 4A included cable, as well as for connecting any digital VTXes. This design makes it a solderless flight controller, ensuring easy assembly and quick swaps in the field.
The Halo Flight Controller is available in two versions, MPU6000 and ICM42688, to meet different pilot preferences.
