라즈베리 파이용 듀얼 채널 MAX14870 모터 드라이버
(Dual MAX14870 Motor Driver for Raspberry Pi)
개요
- 본 제품은 라즈베리 파이와 결합하여 소형 브러쉬 DC 모터를 동작시킬 수 있게 하여 주는 모터 드라이버입니다.
- MAX14870 모터 드라이버를 탑재하여 4.5V-36V에서 동작하여, 다양한 동작 전압을 가진 모터와 사용이 가능합니다.
- 모터당 최대 1.7A 전류를 전달할 수 있습니다.
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
- Board can optionally power the Raspberry Pi base directly through add-on 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
- Reverse-voltage protection on motor power supply
- Under-voltage lockout and protection against over-current and over-temperature
- Surface-mount resistor can optionally be added to enable automatic current limiting
