The FRDM-34931-EVB Expansion Board is an easy-to-use circuit board that allows the user to exercise all the functions of the MC34931EK H-Bridge circuit to drive a brushed DC motor with operation between 5-36 V and up to 5 A. The parallel input in FRDM-34931-EVB can be easily controlled using 3.0/5.0 V compatible laboratory equipment, GPIO of any MCU or through a FRDM-KL25Z board connected to a PC’s USB port. Using in conjunction with FRDM-KL25Z, the Graphical User Interface program provides the User Interface to the USB in FRDM-KL25Z board and allows the user to send commands to the IC.
