I guess I should have guessed what all that empty space on the original Raspberry Pi Pico board was for. They put a WiFi 802.11N chip there. CYW43439 from Infineon. This will be a nice board for IoT. And it's cheap. $6.

Wiznet has RP2040 boards for both ethernet and WiFi: https://eshop.wiznet.io/?ckattempt=1
The ethernet version is $10 and the WiFi $7. They have GitHub libraries for CircuitPython and Arduino. It looks like they have more Flash memory than the Raspberry Pi offering and are in stock. I've used Wiznet ethernet successfully with the MSP430.
