On the site for RPI UF2’s, there are a number of different UF2’s for, what appear to be the PICO W. How do I decide which one to use? Are they described somewhere? Thanks
The pimoroni-picow-v1.19.12-micropython.uf2 is for use with a stock Pico W. One that you plan on adding Pimoroni breakouts too, etc. It has the various custom Pimoroni Micro Python libraries added to it. Pico Graphics, Pimoroni i2c etc.
The rest are each custom builds for each of Pimoroni’s custom “Pico W Onboard” products. They have custom configs for the buttons etc loaded in.
What product page are you looking at? I try and specify what .uf2 to use one recent ones, but we could maybe do with adding some more guidance to some of the older ones - there was only one .uf2 in the early days :)
The 2MB of on-board QSPI flash makes things interesting when trying to make a “it just works” uf2 file. It sounds like a lot of space, but can get used up pretty quickly if your trying to cover a wide range of Pico extras / addons.
Then add into that the Pico, Pico W or custom RP2040 options.
All of the above is just one reason this forum is here. =)
