The Full-Bridge (H-Bridge) is the most popular driver circuit to control brushed DC motors. The main advantage of a full bridge driver is the ability to change the rotation direction of the motor, without manually reversing the supply wires. I’ve already published the Half-bridge and H-bridge driver circuits before; however, I was receiving many requests and comments for a standalone H-Bridge driver to control the DC motors, without using any external board or a controller.

Therefore, I introduced a cheap, compact, and standalone H-Bridge DC motor driver that can be embedded in a variety of mechatronic devices. A cheap ATTiny13 microcontroller controls everything and I used the Arduino IDE to write the microcontroller code. All components, except for the connectors, are SMD.
