라즈베리용 고출력 모터 드라이버 애드온 - 6.5V-30V, 22A
(Pololu Dual G2 High-Power Motor Driver 18v22 for Raspberry Pi)
개요
- 본 제품은 라즈베리 파이용 고출력 DC 모터 드라이버 애드온 보드입니다.
- MOSFET H-Bridge를 탑재하고 있으며, 6.5V-30V 동작범위를 가지고 있습니다.
- 방열판 없이 22A까지 전달이 가능합니다.
- 기본적인 전류 제한 기능을 가지고 있으며, ultrasonic PWM 주파수 사용이 가능하여 조용한 동작이 가능합니다.
특징
- Operating voltage: 6.5 V to 30 V (absolute maximum; not intended for use with 24 V batteries)
- Output current: 22 A continuous
- Active current limiting (chopping) with approximate default threshold of 60 A (can be adjusted lower)
- PWM operation up to 100 kHz
- Motor indicator LEDs show what the outputs are doing even when no motor is connected
- Integrated 5 V, 2.5 A switching step-down voltage regulator powers the Raspberry Pi base for single-supply operation
- 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
- Current sensing and limiting pins are exposed for advanced use
- Reverse-voltage protection
- Undervoltage shutdown
- Short circuit protection
