FireBeetle Covers - DC Motor & Stepper Driver

INTRODUCTION

DFRobot FireBeetle series are low power consumption microcontrollers designed for Internet of Things (IoT) development. FireBeetle Covers-DC Motor & Stepper Driver is a DC motor & Stepper Motor driver designed for FireBeetle Microcontrollers. It can control up to four-channels DC motors / two-phase four-wire stepper motors simultaneously.
The motor driver cover integrates a STM8 as its coprocessor, controlling the motor speed and direction. It communicates with Microcontroller via I2C port, supports up 1000Hz refresh rate. The assisted processor STM8 controls motors and set the main control free. It effectively reduces the dependence on MCU pin resources and MCU occupancy. Independant motor control make the multi-motors projects more affordable. Cooperate with DFRobot Arduino Motor Library, it will reduce your development difficulty.
This stepper motor driver adopts 2x TB6612FNG chips and performs excellent in low power consumption application. The consumption current is only 30mA under static state, and motor driver can provide 1.2A output current at 5V and the peak current is 3.2A@5V. Besides, the motor drive supports 4~12V wide-range power input. FireBeetle Covers-DC Motor & Stepper Driver also provides four independent interfaces to drive servo. So, you can control servo directly. It can be widely applied to intelligent car control and gear control.
