Raspberry Pi and Raspberry Pico are entirely different and unrelated devices.

I've been using the original Pico and also the Pico-W (with WiFi for one more 
dollar) for a bunch of projects; they work well and the price is hard to beat.  
The PIO (programmable state machine) subsystem is particularly impressive; for 
example, I used it to implement a DDCMP sync line interface.
