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 (using the Apache2 server) which allows you to change the state of ...

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. Other languages and libraries are much slower, but the RPi.GPIO ...

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 ...

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 ...

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 ...

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 ...

Four years after the release of the Raspberry Pi 4, the Raspberry Pi team is back ... it also replaces most of the analog components of the main SoC: GPIO and associated low-speed peripherals ...

One of the few downsides seems to be boards like the Odroid XU4 require additional add-ons to make its GPIO pins compatible with Raspberry Pi expansion boards and add-ons. Some powerful single ...

Nearly everything on the Raspberry Pi 5 has improved ... camera and display interfaces, and GPIO, with all of it connected back to the AP by PCI Express. Many Pi users face frustrations with ...

The Raspberry Pi 4’s GPIO header also supports more connections, with UART, SPI, and I2C interfaces each supported on four additional pins, and with fixed support for clock stretching over I2C ...
