The invention discloses a double-MSP430-based integrated motor control and information acquisition circuit, which has the functions of multi-sensor information acquisition and motor control and belongs to the automatic control technical field. The double-MSP430-based integrated motor control and information acquisition circuit aims at integrating the motor control with the multi-sensor information acquisition, so as to meet the requirements of multi-sensor information acquisition and motor control. The double-MSP430-based integrated motor control and information acquisition circuit consists of a control core for double MSP430 microprocessors, four driver modules for the stepping motor, an information acquisition module, a RS232 communication module and a power module. The double-MSP430 control core realizes the motor control and the multi-sensor information acquisition respectively; wherein, the information acquisition part comprises a GPS module, a remote signal receiver module, and a variety of sensor interface modules; the stepping motor control part consists of four driver modules for the motor which can simultaneously control the operations of four stepping motors. With excellent extensibility, the whole system can realize the multi-sensor information acquisition and processing as well as the motor control. Moreover, the circuit board is uniquely designed into an arc shape.
