The Pinouts Book is a free digital book created for designers and engineers as a quick reference for remembering the different pinout functions in your electronics projects.
The book covers 200 commonly used components, such as connectors, single board computers, dev boards, memory cards, microcontroller chips, and more.
If you need more technical information, each page has a link at the top (e.g. pinouts.org/XXX), and these redirect to any official datasheets / specifications we could find.
This latest version has been reformatted for A4 printers, so it's easy to print off the pages that you need.
Happy building :)

The book will always be free, but if you’d like to support what we’re doing, we’ve designed some merch based on the illustrations in the book. Lots of colors & options available.
