Datasheet

The Simple-H does not have any on-board logic to interpret R/C, serial or other
commands. An external signal source is required to translate command inputs
into the PWM 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 the parallel port or via a USB port expander.
Six command/status connections are provided via an 8-position screw terminal on
the Simple-H. The hole spacing allows a standard 0.1" pin header to be
substituted for the screw terminal if desired. Jumpers allow the user to configure
the Simple-H as a single full H-bridge or two independent 1/2 bridge circuits. The
1/2 bridge circuits may be ganged together for increased current handling.
