HR8833 Dual DC Motor Driver

Introduction

This is a ultra compact size Dual-H-Bridge dc motor driver (Based on HR8833), which could drive two way 1.5A DC brush motors up to 10V . It has the same footprint as your thumbnail suitable for projects with limited spaces. Both sides of the module are desgined with standard XH2.54 pins, which allows you to plug it on a breadboard or prototype board.

Specifications

The logic part of the input voltage: 3.3-5V
Driven part of the input voltage Vs: 3.3-10V
Maximum continuous operating current: 1500mA(Single)
Support PWM speed control mode
Maximum power dissipation: 25W (T = 75 degree Celsius)
Working temperature:-20~85℃
Module Size: 18mm × 13mm
