    The Robot Power Simple-H is a low-cost robust H-bridge circuit suitable for use driving DC motors and other DC loads in the ~25A and 6V-28V range. A wide range of command sources from switches to 555 timer circuits to microcontrollers, BasicStamps and Arduinos may be used to control the Simple-H. The classic "green" Simple-H requires 3V-5V logic level signals on its command inputs.

    The Simple-H does not have any on-board logic to interpret R/C, serial, analog voltage or other commands. An external signal source is required to translate command inputs into the switching signals needed to drive the Simple-H power chips. This flexibility allows the Simple-H to be driven from from a signal source as simple as a pushbutton or as complex as a microcontroller or BasicStamp. Even a desktop or laptop PC can be used through a parallel port or USB port expander.

    Unlike many competing products which advertise similar current ratings, the Simple-H ratings are for a period measured in minutes or hours not a few seconds or less. One competitor even advertises a 30A controller where the 30A rating is for "a few milliseconds". With a Simple-H you can be sure if you need 20A of current you can get 20A out of it for as long as you need it.
