Power supply using individual external input sources for
each of the voltage rails 3V3, 1V8 and VIO.
External supplies are connected at the bottom of the EVK
carrier board.
Note: VIO can also be connected to VBAT or 1V8 to supply
it from the same external 3.3 V or 1.8 V source.

PCIe interface
The EVK can be connected through a PCIe connector for Wi-Fi communication with the host system.
Adapters for M.2 Key E and mini-PCIe connectors on host side are included in the kit. The PCIe host
interface connector (J203) is shown in Figure 12.

VDD_PCIE
is connected to the power supply connector (J106) and is used for supplying 3.3 V for
VBAT
from the PCIe interface.
4.5
SDIO interface
The EVK can be connected through a micro SDIO connector for Wi-Fi communication with the host
system. The SDIO connector can optionally be used for Bluetooth. The SDIO host interface connector
(J204) is shown in Figure 13.
