10 A Motor Shield for Arduino

Description

Shield for Arduino based on an H-bridge made up of 4 NMOS transistors which, besides providing better efficiency, allow you to avoid using a heat sink. Suitable for DC motors with a supply voltage from 7 Vdc to 25 Vdc and a maximum current of 10 A. Compatible with Arduino UNO, Arduino Duemilanove, Arduino Mega, Arduino Leonardo or other microcontrollers. It features a screw terminal for motor connection, test buttons, inputs for external control, status LEDs, jumpers for selecting PWM and DIR pins, a reset button, and male/female pin strips that allow stacking other boards. Dimensions (mm): 76×56.

Technical specifications

• Logic level input 3.3 V and 5 V
• Uses an H-bridge made of NMOS for better efficiency and to avoid the need for any heat sink
• Motor rotation direction selectable
• Selectable digital pins for PWM and DIR
