Operating principle and design

The FOXAIR GEMINI 4IN1 controller is an electronic device for controlling the rotation speed of brushless motors. It receives signals from the flight controller using modern digital protocols. The powerful AT32F421K8U7 processor instantly processes the pilot's commands. The regulator then supplies the precisely calculated voltage and current to the motor windings. This happens hundreds of times per second to ensure perfect rotation synchronization.

The regulator board adopts advanced technology with 8 layers and 3 oz copper thickness. This ensures excellent conductivity and efficient heat dissipation under high loads. Modern MOSFET transistors NTMFS5C410NT1G with low open-channel resistance are used. Built-in TVS diode protects electronics from dangerous voltage surges. Bi-directional Dshot support allows you to read motor speeds for precise control.
