I wanted to create an accessible alternative to the official Pico pinout image, offering more complete pin details, light/dark modes, screen-readable text, and at least some capacity to focus on the peripherals you’re interested in. It’s a sister site to the now ancient Raspberry Pi pinout (<a href="https://pinout.xyz/" rel="nofollow">https://pinout.xyz/</a>) which started out life hosted on a Raspberry Pi.
The pinout design is nice, but I'm almost more impressed by the favicon – its very clever and looks great (I noticed it when bookmarking the site).
The last time I worked on a raspberry pi-based project I made extensive use of pinout.xyz, and this new page looks to be a great evolution - thank you for creating them!
