The Raspberry Pi takes 5 volts to run, and you can connect it directly to the GPIO (general purpose input/output)—the 26 pins next to the yellow video out socket (shown above).

Using the same experimental setup, the Raspberry Pi 2 is about 2 to three times faster. The fastest is still the C native library, topping out at just under 42 MHz.

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.

Set up and configure your Pi If you have just bought your Raspberry Pi, this command is one of the first tools you’ll use to set it up. To use it, open the terminal and run 'sudo raspi-config ...

With Opto-pi, there is not an electrical connection between the Raspberry Pi and connected loads (motors, relay coils, etc.) or input signals. Opto-pi uses light to isolate the 8 digital GPIO pins.

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 ha… ...

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 ...

Externally, the Raspberry Pi 5 looks like its predecessors. The size of the board is unchanged, as is the 40-pin GPIO strip. The USB ports and the network socket have been swapped compared to ...

The Raspberry Pi team is back with a new small-but-mighty computer, the Raspberry Pi 5, with updated components and better specifications.
