Description

A simple PCB to take an ATX PSU (especially a PICO ATX board) and provide +5v, -5v and 12v. Whilst ostensibly for the Camputers Lynx this will also be useful for many other older devices which need the, often tricky to get, -5v supply.

 

The V7805 can probably be changed to a 7905 if you take the source from the -12V line of the ATX, but then you'll also have to make changes to deal with the heat output.

 

The PCB also has points for an LED, FAN and SWITCH. The LED and FAN are optional, but probably useful if placed into a case, the switch is needed to activate the ATX supply.
