Monolithic Power Systems (MPS) EVKT-LT-KNOB Evaluation Boards are accessory plastic knobs equipped with a cylinder magnet. The boards are designed to fit all TBMA-LT evaluation boards. The MACOM evaluation kit connects the TBMA-LT evaluation boards to a PC, while the MACOM GUI displays rotational motion. The magnet is diametrically magnetized to produce the correct input signal for MPS’ MagAlpha family of sensors.
