Connectors
I/O:
Dual row 0.1” 50 pin shrouded headers with grounds on all
even pins
DC power jack: 2.0mm positive center post (for use primarily with AC/DC
converters, or “wall-warts”)
DC power screw terminals available via enclosure cutout
Power
Basic 48 bit unit:
+5VDC from external regulated power supply, <300mA typical (no load)
Auxiliary Outputs:
+5VDC via one 0.5A resettable fuse for both connectors
Max power consumption is 2.0A under full load conditions (all I/O’s
configured as outputs sourcing 32mA each and 500mA draw from +5VDC
fused outputs.)
