Description

The iMTQ MagneTorQuer board is a PCB based 3-axis magnetic system. It is designed to provide maximum flexibility in placing actuators and magnetometer in a CubeSat structure. Providing actuation of 0.2Am2, the system can be placed in a stack or in between stacks in ISISPACE CubeSat structures. The magnetorquer board can be controlled over digital or analog interface and provides telemetry over I2C.
