44 Reference Manual CoreModule 420
Power Interface (J7)
The CoreModule 420 requires one +5 volt DC power source and uses a 10-pin header with 0.1" spacing.
If the +5VDC power drops below ~4.65V, a low voltage reset is triggered, resetting the system.
The power input connector (J7) supplies the following voltages and ground directly to the module:
• 5.0VDC +/- 5% @ 1.35 Amps
Table 3-19 gives the signals for Power supply pin outs.
