MikroElektronika has just introduced the MIKROE-3031 H-Bridge Click high-efficiency dual H-bridge driver add-on board. With low power consumption, under-voltage protection and thermal protection, this item of hardware provides simple stepper motor driving with four control pins. The desired logic voltage can be selected between 3.3V and 5V. It is capable of delivering high current while driving the connected load (up to 7V).
The board is equipped with a dual H-bridge MC34933 driver IC, enabling driving in both directions with an addition of brake and high impedance modes. It is suitable for use in light 3D printer element driving, precision actuators and accurate positioning of various moving elements by using stepper motors.
