If you are building a robot with wheels, you need a dual H-Bridge driver like this one.
is a great dual motor driver that is perfect for interfacing two small DC motors such as our micro metal gearmotors to a microcontroller, and it can also be used to control a single bipolar stepper motor. The MOSFET-based H-bridges are much more efficient than the...
The best battery connectors on the market just got better with the development of the EC3, also called the EC3
The new EC3 features snap on insulating end caps which provide extra grip and heart-shrink free installation. They also have a design change which is far more user-friendly for connection and disconnection with an improved integrated grip area.
