라즈베리용 듀얼 모터 드라이버 쉴드 HAT-MC33926

(Pololu Dual MC33926 Motor Driver for Raspberry Pi)

 

개요

  • 본 제품은 라즈베리 파이용 모터 드라이버 쉴드(HAT)입니다.
  • 라즈베리 파이 B+, A+, 파이 2와 사용이 가능하며 두개의 DC 모터를 동작시킬 수 있습니다.
  • 5V-28V와 동작하는 MC33926모터 드라이버칩을 장착하였으며, 채널당 3A(피크시 5A)까지 전달할 수 있습니다.

특징

  • Wide operating voltage range: 5 V to 28 V
  • Output current: 3 A continuous (5 A peak) per motor
  • PWM operation up to 20 kHz, which is ultrasonic and allows for quieter motor operation
  • Motor indicator LEDs show what the outputs are doing even when no motor is connected
  • Board can optionally power the Raspberry Pi base directly through added regulator (not included)
  • Python library makes it easy to get started using this board as a motor driver expansion board
  • GPIO pin mappings can be customized if the default mappings are not convenient
  • Remaining motor driver pins are exposed for advanced use
  • Reverse-voltage protection on motor supply
  • Robust drivers:
    • Transient operation (< 500 ms) up to 40 V
    • Internal peak-current limiting gracefully reduces the output power if the current or temperature get too high
    • Under-voltage shutdown
    • Output short-to-ground and short-to-Vcc protection
  • Prototyping space for easier/cleaner construction of custom circuits
