DRV8837 1st Road DC H bridge motor driver module 1.8A step motor motor drive board

Introduction to the characteristics of DRV8837 drive board:

Size: 15* 20mm

Input voltage: 1.8 V -7 V

Single H bridge output current: 1.8A, which can drive 2 DC deceleration motors.

Built -in overcurrent protection, short -circuit protection, low -pressure atresia and overheating protection.With low power sleep mode.

Uses: The product can drive DC motors and 4 -line steps into the motor below 1.8A.

Explanation of the tube:
IN1: A chip pwm input 1, voltage range: -0.3-7V

IN2: A chip pwm input 2, voltage range: -0.3-7V

OUT1: A motor drive output 1, voltage range: -0.3-7V

OUT2: A motor drive output 2, voltage range: -0.3-7V

IN1 and IN2 are the output port of 1 H bridge, connecting two feet of a DC motor.
