Power Interface
The CoreModule 745 requires one +5 volt DC power source and provides a shrouded 10-pin, right-angle
header with 2 rows, odd/even pin sequence (1, 2), and 0.100" (2.54mm) pitch. If the +5VDC power drops
below ~4.65V, a low voltage reset is triggered, resetting the system.
The power input header (J7) supplies the following voltage and ground directly to the module:
•
5.0VDC +/- 5%
