0-SMPH Simple-H H-bridge <p align="left"><font color="00ff66" size="2" face="Arial, Helvetica, sans-serif">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 24V range or less. A wide range of command sources from switches
to 555 timer circuits to microcontrollers and BasicStamps may be used to control the Simple-H.

<p align="left"><font color="00ff66" size="2" face="Arial, Helvetica, sans-serif">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.</font></p>
