my dev. board: Raspberry Pi Pico 2 W

Currently (24-11-30), there are no official firmware in micropython.org. You can download the preview version here. scroll down to download MicroPython UF2 for Pico 2 W (mp_firmware_unofficial_latest.uf2).

As first test, I try to blink the onboard LED by following https://projects.raspberrypi.org/en/projects/getting-started-with-the-pico, but failed.

Later, I found the reason: Refer to Raspberry Pi Pico 2 W Datasheet  and schematic, Pico 2 W (should be same as in Pico W) onboard LED is connected to CYW43439KUBG chip, not RP2350, so have to specially handled like this:

led = machine.Pin("LED", machine.Pin.OUT)

blink.py, MicroPython code to blink the onboard LED

from machine import Pin, Timer
led = machine.Pin("LED", machine.Pin.OUT)
print("led:", led)

timer = Timer()

def blink(timer):
    led.toggle()

timer.init(freq=2.5, mode=Timer.PERIODIC, callback=blink)

while True:
    pass
