When the RPi Pico W was announced in June I was very happy as I've wanted to get an inexpensive WiFi version of the RP2040. Unfortunately, to date, I haven't been able to get one.
I noticed that the WizFi360 EVB Pico is available in distribution (Digikey less than $7).
And more recently I noticed on Hackster that Wiznet was having a design contest and giving away free samples for projects (3 different modules including the one with the Pico).
I applied and received a free sample. It arrived this weekend, slightly worse for shipping - the exterior box was crushed (I plumped it up a bit), but luckily the board was not (love those padded envelopes).
The WizFi board has a couple of shortcomings relative to the Pico W. It retains the Pico footprint/pinout, but is longer because the WiFi module is just tacked on the end. And it only does WiFi, while the Pico W uses an Infineon CYW43439 chipset capable of WiFi/BLE (although to be fair - BLE has not been implemented in the firmware yet).
I have a number of sensors that I use WiFi only, so I'll probably make good use of the WiZFi board and best of all it's available...
