Now instead of wrangling Python or PHP to do your bidding, [Eric] came up with a way to control the GPIO pins on his Raspberry Pi in a browser. [Eric] calls his project WebIOPi, and it’s the perfect ...

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 ...

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 ...

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 ...

General purpose input-output (GPIO) pins are the simplest peripherals. The link to an object under control (OUC) may become inadvertently unreliable due to many reasons: a loss of contact, short ...

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, ...

This post addresses the specific hurdle of effective and efficient manufacturing tests for these complex devices. It outlines ...

Raspberry Pi enthusiasts looking for a quick way to add GPIO pins for prototyping that can be then easily removed once the project is finalised, are sure to be interested in a new PCB quick clip ...
