This shield makes it easy to control two high-power DC motors with your Arduino or Arduino-compatible board. Its twin discrete MOSFET H-bridges support a wide 6.5 V to 30 V operating range and are efficient enough to deliver a continuous 18 A without a heat sink. The drivers offer basic current sensing and current limiting functionality, and they accept ultrasonic PWM frequencies for quieter operation. The Arduino pin mappings can all be customized if the defaults are not convenient, and the motor driver control lines are broken out along the left side of the shield for general-purpose use without an Arduino.
Details
- Operating voltage: 6.5 V to 30 V (absolute maximum; not intended for use with 24 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)
This version, the 18v18 motor driver shield, can be distinguished from the other versions by its blue PCB and the number 150 on top of the tall silver electrolytic capacitors
Features common to all versions
- 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)
Included hardware
This motor driver board ships with all of the surface-mount parts populated. However, soldering is required for assembly of the included through-hole parts. The following through-hole parts are included:
- one extended/stackable 1×10 female header (for Arduino shields)
- two extended/stackable 1×8 female headers (for Arduino shields)
- two extended/stackable 1×6 female headers (for Arduino shields)
- three 2-pin 5mm terminal blocks (for board power and motor outputs)
- 40-pin 0.1″ straight breakaway male header (may ship in several pieces, such as two 20-pin strips)
A 0.1″ shorting block (for optionally supplying shield power to Arduino) is also included.
