The pinouts diagram for the Raspberry Pi Pico is miserable when printed on a monochrome laser printer. Fortunately is was in SVG so I took a copy, drug it into Graphic (the tragic rename by Autocad) and made it boring but legible. (Assuming you are on a white background. It is displayed here on the view default, and in dark mode looks like garbage).
I don't print enough color to keep the ink live in my inkjet printers and HP abandoned my networked color laser printer (then a mouse ate part of it).
If you find yourself in the same position, then enjoy! Here it its PDF and SVG glory.
The PDF is down in the attachments.
