HDZero Halo is a high-end flight controller in a Mini size, designed for both racing and freestyle drones. This flight controller is unique as it features an integrated dual ELRS receiver operating at 2.4GHz with full diversity and a TXCO crystal. It supports the Gemini mode for maximum reliability and minimal RC transmission latency. The board has a 20x20mm mounting hole pattern and supports 3-8S LiPo battery power input.
The core of the flight controller is a powerful H743 processor. It includes a 5V/4A BEC for powering LED strips or a GPS module and a switchable 9V/3A BEC for video transmitters. The HDZero Halo is designed for use with digital video transmitters and therefore does not have an OSD chip for analog video. The board features connectors for ESCs and digital video transmitters. It also includes 16MB of memory for blackbox logging. Additionally, it has exposed I2C pads for connecting a compass or barometer.
The flight controller is available in two versions with either the MPU6000 or ICM42688 gyro.
