Power supply configuration
JODY-W3 series modules are supplied with 3.3 V (
3V3
), 1.8 V (
1V8
) and a
VIO
voltage that can be
either 3.3 V or 1.8 V. Power supply for the EVK can be provided over the different host interfaces or
from external sources. The following power supply options are available on the EVK:
•
PCIe, SDIO, USB interfaces: The EVK is powered through the host interface. All internal voltages
are generated by DC-DC converters on the EVK.
•
External power supply (VEXT): EVK-JODY-W3 can be connected to an external power supply of 7 V
to 24 V. DC-DC converters are used for generating all the required internal voltages.
•
Individual supply: All the individual voltage rails
3V3
,
1V8
and
VIO
are supplied from external power
sources.
