Input power may be supplied either through this connector, the I/O power connector, or directly
through the PC/104 bus power pins.
Pegasus requires only +5VDC input power to operate. However since the PC/104 bus includes pins for
+3.3V and ±12V, these voltages may be supplied through this connector if desired. Also if a 3.3V LCD is
used, then 3.3V must be supplied through this power connector. Multiple +5V and ground pins are
provided for extra current carrying capacity if needed. Each pin is rated at 3A max. For applications
requiring less than 3A, the first 4 pins may be connected to a standard 4‐pin miniature PC power
connector, or the alternate power I/O connector may be used.
I/O POWER CONNECTOR (IO_P1)
This connector provides an alternate connector for either input power to the system or output power
for use with external drives.
Diamond Systems' cable number 6981006 mates with this connector. It provides a standard full‐size
power connector for a hard drive or CD‐ROM drive and a standard miniature power connector for a
floppy drive.
EXTERNAL BATTERY CONNECTOR (EBAT1)
This connector provides a means to connect an external battery to the Pegasus SBC.
ETHERNET CONNECTOR (LAN1)
Pegasus supports both a pin header and an optional RJ‐45 jack for Ethernet signals. The pin header pin
out is shown here. The RJ‐45 pin out matches industry standards. The LED signals are referenced to
ground.
