When the first Raspberry Pi rolled off the production line back in 2012 it sported a 26-pin expansion header that seemed to conceal endless possibilities. A later upgrade to the 40-pin header we have ...

Mini PCs replaced almost every Raspberry Pi I own, but GPIO pins kept one on my desk ...

GPIO Zero is built on top of existing software libraries to the Pi’s hardware – to the GPIO lines hence GPIO libraries. You can use these libraries directly but they generally work in C and are not ...

Raspberry Pi owners looking to use higher voltages with their mini PC, might be interested in this new opto-isolator board called the Opto-pi which has been specifically designed to be used with the ...

In addition to being a serviceable single board computer, the Raspberry Pi also has a header full of GPIO pins at your beck and call. [Tedbot] sent in a great tutorial on using these pins with Python, ...

There's still a place for learning to code the old-fashioned way, and it's more fun than you think.

The Raspberry Pi 5 hosts a dual-row 40-pin male header that allows access to its inter-integrated circuit (I2C), serial peripheral interface (SPI), serial port, and general-purpose input/output (GPIO) ...

How much can you cram into a 2.6 in x 1.2 in circuit board? You'd presume not much, but the Raspberry Foundation is trying to prove you wrong. First, it added built-in Wi-Fi to its teeny Raspberry Pi ...

This article presents the first of a six-part series of learning the peripheral functions of a microcontroller that is the GPIO (General-purpose Input/Output). It discusses the important peripheral, ...
