The Pinouts Book helps you understand components and boards
The Pinouts Book is a free PDF download contains over 300 pages of high-contrast hardware diagrams and their respective pinouts.
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 130 commonly used components (view list), such as connectors, single board computers, dev boards, memory cards, microcontroller chips, and more (includes 11 Adafruit boards, but we’re not involved in this).
If you need more technical information, each page has a link at the top (e.g. pinouts.org/XXX), and these redirect to official datasheets / specifications.
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

I think it would be a good idea to have a version that does not use black backgrounds for the line drawings, if you try to print it on an inkjet, which is the most common printers that people have, you will burn through a lot of ink and end up with a pike of very soggy pages.
Just provide an inkjet version that has the drawings all reversed, black for white.
