Power requirements
The ISIS operates from +5V (+/-5%) power input. All other supply rails are generated on-
board.
A +12V supply connection is provided through J9, however the ISIS does not use this.
The +12V and –12V rails are routed to PC/104-Plus and PC/104 connectors and can be
used by other devices or modules that are stacked onto the ISIS module. -5V supply
connection is also provided at the power input connector (
J9 - Auxiliary power connector
and is only routed to the PC/104 connector for use by PC/104 add-on modules.
An external coin cell battery input is available through an 18-way header (
Multifunction and VGA connector
). An optional on-board SuperCap is provided. Jumper
JP3 is used to connect an on-board SuperCap (see page
for details).
