The GPIO pins on the Raspi are arranged in a 2×13 header. Until Sparkfun manages to manufacture a decent Raspi protoboard, the easiest way to break these pins out is with an old IDE ribbon cable.

Here’s a Raspberry Pi hack that adds web control using PHP and MySQL. As you can see in the image, it serves up a webpage ... which allows you to change the state of the GPIO pins.

The Raspberry Pi Opto-pi board has been created to make interfacing with the 8 digital GPIO pins on the Raspberry Pi mini PC much easier. Allowing you to connect higher current devices as well as ...

Raspberry Pi enthusiasts that would like to learn a little more about the GPIO pins on the Pi mini PC and how they can integrated with other electronics to build circuits and projects, ...

One of the biggest draws of the Raspberry Pi family of single board computers or SBCs is their expandability. That comes via the standard 40-pin GPIO header on the full-sized boards.

Two 5v pins are powered directly from the Pi's power supply, and two 3.3v pins are regulated down to this common voltage, leaving you with 31 unique pins and 28 true GPIO pins.

For the Tx, with the pins facing you, attach the Raspberry Pi GPIO 0 to the leftmost pin, 5V to the middle, and ground to the right pin. Ground and 5V are from the Raspberry Pi, and the pins may ...

The Raspberry Pi board has a 40-pin GPIO header on it that needs through-hole soldering, along with bits like the Ethernet and USB ports. These require robust solder joints, ...

Raspberry Pi GPIO Pin # 1 (17*) 24: 21: 25: 19: 23: So when I wired things up, I connected pin 2 of the Pomona clip to GPIO pin 17, but in other guides, they use GPIO pin 1 for 3.3V. I list both ...
