I just pushed the v2.1 documentation release out the door. This is a major update to the @Raspberry_Pi #Pico, #PicoW, and #RP2040 PDF documentation. You can grab the documentation directly from https://datasheets.raspberrypi.com. Or go to https://raspberrypi.com/documentation/microcontrollers/ for links to what you need.
