CPU Voltage
J4 and J5 set the CPU voltage.
Each CPU can be independently set
to the correct CPU core voltage. The factory setting for both CPUs is
3.3V. It should not be changed unless the CPU is rated differently. J4
sets the CPU voltage for the CPU in U14. J5 sets the CPU voltage for the
CPU in U15. The CPU voltage settings:
