1VV0301663 Rev.1Page 14 of 20 2020-08-10
Figure 9: Power Configuration jumpers (PL202-PL204)
Basically, the jumper PL202, PL203, PL204, are used to separate each power lines from the
rest of the EVB to allow current consumption tests.
3V3 Power:
•Place jumper on PL203 1-2 and PL204 1-2, allows to supply the 3.3V to Wi-Fi module
•Place jumper on PL203 1-2 and PL202 1-2, allows to supply the 3.3V to another device
(like USB to UART block) which use 3.3V.
1V8 Power:
•Place jumper on PL203 5-6, allows to supply the 1.8V to audio codec.
Slide switch located on the right side of the above figureFigure 9:, allows to supply or cut the
EVB main power.
•ON: Allow to supply the power to EVB.
•OFF: Allow to cut the power to EVB.
Current consumption measurement jumper and description are as shown below:
Figure 10: Current Consumption Measurement
Measure the module current consumption:
•Place jumper on PL203 1-3 and 2-4.
•Remove jumper on PL203 5-6 and PL202 1-2.

4. WE310F5-I/P BASIC OPERATIONS
General Information on Power Supply
This EVB is mainly designed for SW development,
The board can be power supplied in different ways:
1) Direct USB supply by means of a USB cable (5V, 500mA) on micro b USB connector.
2) By means of a standard lithium 3.6V battery plugged into the SMD battery connector
on the bottom side (the WE310F5-I/P does not embed a battery charger),
3) By plugging Arduino on the bottom side, if you supply Arduino Uno-Rev3 board with its
own supply source (Arduino Shield)
The WE310F5-I/P is not able to supply the Arduino board.
The power sources 1-3 activate a DC/DC and an LDO that create the 3V3 and 1V8 necessary
to the board operation.
Program and Run the WE310F5-I/P Module
To Program and Run the module, please refer to WE310F5 AT Command Guide for more
details.
