3.5 Switches
The following are the available switches on the WFI32-IoT board:
• User-configurable switches – ( SW400 ) and ( SW401 )
• Reset switch ( SW402 ) – Connected with the MCLR signal of the WFI32E01PC module
In the Idle state, the level of the user-configurable switch is pulled high (+3.3V) and, when the switch is pressed, it
drives the I/O line to low (GND).

Switch Name Description Pin on WFI32E01PC Module
SW400 User configurable switch2 PGC4/TCK/AN8/CVD8/CVDR8/RPB8
SW401 User configurable switch1 INT0/AN17/CVD17/CVDR17/RPA10
SW402 Reset switch MCLR
3.6 LEDs
The WFI32-IoT on-board LEDs are categorized into three types:
• Power LEDs
– Green ( D101 ) – Charge indicator
– Red ( D100 ) – Low battery indicator
– Blue ( D102 ) – Power indicator
• PKOB4 LEDs
– Green ( D300 ) – ACTIVE indicator
– Yellow ( D301 ) – STATUS indicator
• LEDs related to the WFI32E01PC module:
– Red LED ( D400 )
– Yellow LED ( D401 )
– Green LED ( D402 )
– Blue LED ( D403 )
The following table lists the LEDs that can be turned ON or OFF using the connected GPIO pins.

3.7 Temperature Sensor
The MCP9808 digital temperature sensor converts temperatures between -20°C and +100°C to a digital word with
±0.25°C/±0.5°C (typical/maximum) accuracy. For more details, refer to the
MCP9808 ±0.5°C Maximum Accuracy
Digital Temperature Sensor ( DS20005095 ).
The following are the additional features of the MCP9808 digital temperature sensor:
