HDZero Halo Mini Flight Controller ICM42688

Product detailed description

HDZero Halo Mini Flight Controller is a compact, high-performance flight controller built for modern digital FPV setups. The ICM42688 gyro version targets pilots who want fast response, clean logs, and stable flight behavior even with higher-frequency vibrations. It features an integrated ExpressLRS 2.4 GHz Gemini true diversity receiver, which eliminates the need for an external RX and keeps the build clean and lightweight. With strong onboard BEC outputs, it delivers reliable power for your video system and peripherals.
