Table 5 shows the (J104
–
J106) jumper positions for selecting the power supply source for the EVB.
Power supply source
Jumper configuration
3.3 V from PCIe interface
Use the M.2 or mini-PCIe adapter with the flat cable to connect to the host system.
3.3 V from SDIO interface
Use the micro SDIO adapter with the flat cable to connect to the host system.
5 V from USB interface
Use the Type-C USB cable to connect to the host system.
Note: The USB host port must be able to deliver a current of up to 1000 mA for Wi-Fi
operation. The current provided by a standard USB 2.0 interface is sufficient for Bluetooth-
only operation.
5 V
–
24 V external power supply
External supply must be connected to the power jack J11 or J100. The external supply
voltage is converted to 3.3 V using a DC-DC on the EVB.
J11: 2.1 x 6.3 mm DC power jack
J100: Phoenix Contact 1721986
All input voltages supplied from separate external sources
External supplies must be connected to the power jacks located on the bottom side of the
EVB for 3V3 (J101), 1V8 (J103) and VIO (J102).
J101-J103: Phoenix contact 1721986.

Selecting the module input voltage
Use jumpers J1-J7 to select the external power source to the module, as shown in Figure 8.
The input voltage to the module can be sourced from either the on-board DC-DC generated voltages
or the direct input voltages from the separate external supplies J101-J103.
