본 제품은 작은 크기의 아두이노 쉴드로 두개의 소형 브러쉬 DC 모터를 제어할 수 있는 제품입니다.
두개의 MAX14870 모터 드라이버를 탑재하여 4.5V-36V로 동작이 가능하여 높은 전압을 가진 모터와 사용이 가능합니다.
모터당 연속적으로 1.7A의 전류를 전달이 가능합니다.
모터 드라이버의 전원으로 연결된 아두이노의 전원을 공급할 수 있습니다 (옵션)
특징
Two single-channel H-bridge motor drivers with shoot-through protection and internal free-wheeling diodes (can each drive one DC motor)
Motor supply voltage: 4.5 V to 36 V
Output current: 1.7 A continuous (2.5 A peak) per motor
PWM operation up to 50 kHz (ultrasonic frequencies allow for quieter motor operation)
Simple two-pin DIR/PWM interface (one pin controls direction and another controls speed)
Shield can optionally power the Arduino base directly when motor supply voltage is suitable
Shield has convenient location for adding a 3-pin voltage regulator to power the Arduino base in applications where the motor supply voltage is not suitable for powering the Arduino directly
Arduino library makes it easy to get started using this board as a motor driver shield
Arduino pin mappings can be customized (by cutting traces) if the default mappings are not convenient
Reverse-voltage protection on motor power supply
Under-voltage lockout
Active-low fault output indicates over-current or over-temperature condition
Surface-mount resistors can optionally be added to enable automatic current limiting
This library for the Arduino makes it easy to interface with Pololu's Dual MAX14870 Motor Driver Shield and drive a pair of brushed DC motors. A sample sketch is included with the library.
