The AOX-MTQ is a three-axis magnetorquer widely used to control the attitude of the microsatellites. It consists of two magnetic torque rods with metal cores and a small air core torque with low power consumption. The three actuators are independently driven by PWM (Pulse-Width Modulation) signals with the I2C interfaces. In addition, the temperature sensors and current sensors are mounted on the PCB to monitor the operating condition.
