HG7881 H-Bridge 4CH DC - 2CH Stepper Motor Driver Board
This is the HG7881 H-Bridge Stepper Motor Driver Board, which can drive 4 dc motors, or two 4-wire 2-phase stepper motors. This motor drive module comes with its own four hg7881 chips.
The module is appropriate for controlling small robots. It has a convenient set of header pins for connecting with a microcontroller and a set of screw terminals for connecting with motors. The motor's speed can be easily controlled using a PWM (pulse width modulation) signal and digital output.
If you want to control the stepper motor with Stepper Motor Driver Board, for that you will need a few essential components like
