Raspberry Pi GPIO

GPIO boards to buy?

It is useful to know that the pins of the Raspberry Pi 3B+ and the new 4B have the same format. If you need more than the standard 40 GPIO pins for your project, it is possible to extend them using an extension cable to your breadboard† In this way, 40 more pins are added, and therefore more space for fun ideas for your project!

Why a GPIO board to buy?

What to consider when buying a GPIO board?

When buying a GPIO board we recommend getting one reference card In addition, this card can be placed over the pins making it clear which pins are adjustable (IO pins) and which cannot be adjusted (3.3/5V, GND). If these pins are not properly connected, there is a chance that your motherboard breaks, you can prevent this by holding an accessory near the pins while wiring.
