The uSDC or Micro-Shut-Down-Controller is an electronically
controlled automotive power switching device. It is primarily designed
for the purpose of starting up or shutting down a personal computer
used in a motor vehicle. It interfaces with a computer motherboard’s
power switch header that would normally connect to the push-button
switch on the front of a personal computer case. The uSDC includes a
high current relay that will cut off or apply all power to the power
supply of the personal computer to prevent any substantial current draw
when the computer is not in use. The uSDC also provides a timing
mechanism that is user selectable allowing the computer to remain “on”
for an amount of time after the ignition has been turned off. The uSDC
allows the user to mount the personal computer in remote locations
(such as a trunk) and provides hands off method automating the startup
and shutdown sequence while constantly monitoring the environmental
conditions.

Note: This is for a PCB board only. User will have to provide
adequate casing, blade style automobile connectors, and wiring to
