아두이노 고출력 DC 모터 드라이버 쉴드 -40V, 18A
(Pololu Dual G2 High-Power Motor Driver 24v18 Shield for Arduino)
개요
- 본 제품은 두개의 고출력 DC 모터를 제어할 수 있게 디자인된 아두이노 쉴드입니다.
- 6.5V-40V의 동작전압을 지원하며, 방열판 없이 연속적으로 모터를 18A까지 동작시킬수 있습니다.
- 기본적인 전류 센싱 및 전류 제한 기능을 지원하며, 조용한 동작을 위해 ultrasonic PWM 주파수를 지원합니다.
특징
- Operating voltage: 6.5 V to 40 V (absolute maximum; not intended for use with 36 V batteries)
- Output current: 18 A continuous
- Current sense output proportional to motor current (approx. 20 mV/A; only active while H-bridge is driving)
- Active current limiting (chopping) with approximate default threshold of 50 A (can be adjusted lower)
- Inputs compatible with 1.8 V, 3.3 V, and 5 V logic
- PWM operation up to 100 kHz
- Motor indicator LEDs show what the outputs are doing even when no motor is connected
- Reverse-voltage protection
- Undervoltage shutdown
- Short circuit protection
- Control interface allows for sign-magnitude or locked-antiphase operation
- Integrated 7.5 V, 1 A switching step-down voltage regulator (can be set to output 5 V instead)
- Arduino library makes it easy to get started using this board as a motor driver shield
- Detailed user’s guide
- Arduino pin mappings can be customized if the default mappings are not convenient
- When used as a shield, the motor power supply or 7.5 V regulator output can optionally be used to power the Arduino base for single-supply operation
- Can be used with an Arduino or compatible board (through shield headers) or other microcontroller boards (through 0.1″ header along the left side)
