Notes:
1.
For more details on the WFI32E01 pins, refer to the
PIC32MZ1025W104 MCU and WFI32E01 Module with
Wi-Fi
®
and Hardware-based Security Accelerator Data Sheet
(
DS70005425
).
2.
The SPI interface on the click board can operate up to 12.5 MHz and the WFI32E01 module supports up to 20
MHz.

Switches
The following switches are available on the PIC32 WFI32E Curiosity Board:
• User-configurable switch (
SW200
)
• Reset switch (
SW201
) – Connected with MCLR signal of the WFI32E01 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).

jumper to configure the board to
the switch or external interrupt.
