Some initial findings:

The WiFi (+Bluetooth 5.2) chip is Infineon CYW43439, and it is connected to the RP2040 over SPI. The pin assignment is as follows:

RP2040 Pin	CYW43439 Pin	Description
GPIO23	WL_ON	Wireless power on signal
GPIO24	WL_D	wireless SPI data/IRQ
GPIO25	WL_CS	wireless SPI CS *
GPIO29	WL_CLK	Wireless SPI CLK *

* When WL_CS is high, GPIO29 is connected to VSYS (so you can read VSYS via ADC3 input)

This feature has been getting a large number of votes recently, so I ordered a Pi Pico W to prepare for implementation.

Found a blog post with tons of useful information: https://iosoft.blog/2022/12/06/picowi/

Initial implementation of the Pi Pico W is live on Wokwi!

Here are some examples:

• Arduino
• MicroPython
• Pi Pico SDK

documentation and more information coming over the next few weeks.

Just curious, would the Wokwi team consider implementing a CircuitPython version for the RPi Pico W? Since there is already a CircuitPython version for the Pico.

@d3lta-v not a priority for the first release. We aim for Pico SDK and micropython compatibility, since they are both officially supported by the Pi foundation, and Arduino compatibility since Arduino is the most popular platform on Wokwi.

Could you please have a look into connecting a Pico W to a NTP time server using MicroPython:

import ntptime ntptime.host = "pool.ntp.org" ntptime.settime()

After some testing with the Pico-W beta board I and Koepel (discord user) has found out that it's currently unable to connect to WiFi when test example is re-compiled meaning only the pre-compiled test example works as of now.

The current testing has included the following steps.

1. Make a project from scratch with the pico-w beta template, including as well as excluding the cw43 attribute for the board
2. Modifying the existing WiFi example
