Featured Deals

Here are some of our products featured during the RobotShop's Arduino Day celebration: 

Cytron 10A DC Motor Driver Arduino Shield

SHIELD­MD10 is an Arduino shield for controlling high current brushed DC motor up to 10A continuously. It is compatible with Arduino UNO, Arduino Duemilanove, Arduino Mega, Arduino Leonardo and possibly other pin compatible mainboards. SHIELD­MD10 uses full solid state components which results in faster response time and eliminates the wear and tear of the mechanical relay. SHIELD­MD10 shield has stackable side headers which allow for more Arduino shields to be stacked on top of it.
