2503-POLOLU Dual MC33926 Motor Driver Shield for Arduino
This shield makes it easy to control two brushed DC motors with your Arduino or Arduino-compatible board. Its dual MC33926 motor drivers operate from 5 to 28 V and can deliver a continuous 3 A per motor. These great drivers also offer current-sense feedback and 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.
Dimensions
| Size: | 1.90″ × 2.02″ × 0.38″1 |
|---|---|
| Weight: | 10 g1 |
General specifications
| Motor driver: | MC33926 |
|---|---|
| Motor channels: | 2 |
| Minimum operating voltage: | 5 V2 |
| Maximum operating voltage: | 28 V3 |
| Continuous output current per channel: | 3 A4 |
| Current sense: | 0.525 V/A |

Notes:
1. Without included hardware.
2. Operation from 5 - 8 V reduces maximum current output.
3. The device is protected for transients up to 40 V.
4. Can be improved by addition of heat sink or forced air flow.
5. On motor voltage only; logic voltage does not have reverse protection.
