J106) jumper positions for selecting the power supply source for the EVB.
Input voltage
Jumper configuration
3.3 V from SDIO interface.
Use SDIO adapter with the flat cable to connect to the host.
5 V from USB interface.
Use Type-C USB cable to connect with the host.
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.

24 V external power supply.
External supply must be connected to the power jack J11 or J100 and switch S1 must be
ON. 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
See the links in
for further details about terminal connector and power jack.
All input voltages are supplied from individual 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).

Selecting the module input voltages
Use jumpers J1-J7 to select the external power source to the module, as shown in
. 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.
