We’ve gotten used to the GPIO-available functions of Raspberry Pi computers remaining largely the same over the years, which is why it might have flown a little bit under the radar: the Raspb… ...

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 ...

To achieve the task of interfacing now-vintage IDE devices with the Raspberry Pi, [Manawyrm] elected to use the single board computer’s GPIO pins to get the job done. 23 pins are required, with ...

Raspberry Pi 4 – Design and Features. The Model B brings a noticeable spec bump from its predecessor, ... And, of course, it comes with the same 40-pin GPIO header that previous models have, ...

The Raspberry Pi 400 does feature a horizontal 40-pin GPIO header on the rear of the keyboard, so it's possible to add physical HAT extensions, such as a camera.

So we knew we’d need a button, some sound files, a little bit of Python code, and, of course, a Raspberry Pi. A new Pi is $35 , but we found an old Raspberry Pi 2 in my desk drawer, which was up ...
