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.

Of course, the Pi’s GPIO pin’s aren’t long enough to efficiently transmit at 304.2 MHz, so [River] added a proper antenna, as well as a low-pass filter to clean up the transmitted signal.

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.

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 ...

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.

Tom Fox has created a capacitive touch sensor using a Raspberry Pi Pico that makes use of all 26 pins with his custom PCB he calls Spoke.

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, ...
