The WiFi (& Bluetooth) IC used in the Pi Pico W retails for ~$2.5, and presumably a bit less in volume (considering the Pico W is only $2 more than the base Pi Pico.

Esp32-c3 super mini is less than $2 with free shipping from AliExpress. The usb-c cable I use to power it is more expensive. I get a serious cognitive dissonance when I think about it too much.

you can get certain variants of the esp32 at around 2USD. that gets you a whole board with USB-c.

Where can you find it for $2.5? The last I looked, it was around $6.

They are talking about the radio chip that's on the Pico W. not the whole pico w.
