Hardware Specification

Pin-out v1.0

PIN-OUT IMAGE COMMING SOON

W6300-EVB-Pico2 pinout is directly connected to the GPIO of RP2350 as shown in the picture above. It has the same pinout as the Raspberry Pi Pico2 board. However, GPIO15, GPIO16, GPIO17, GPIO18, GPIO19, GPIO20, GPIO21, GPIO22 are connected to W6300 inside the board. These pins enable QSPI communication with W6300 to use the Ethernet function. If you are using the Ethernet function, these pins cannot be used for any other purpose.

The RP2350 GPIO used inside W6300-EVB-Pico is as follows.

I/O	Pin Name	Description
O	GPIO15	Connected to INTn on W6300
O	GPIO16	Connected to CSn on W6300
O	GPIO17	Connected to SCLK on W6300
I/O	GPIO18	Connected to IO0 (MOSI) on W6300 (QSPI)
I/O	GPIO19	Connected to IO1 (MISO) on W6300 (QSPI)
