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 ...

The TV HAT costs about $20 and can be attached to any Raspberry Pi board with a 40-pin GPIO. It's available from Raspberry Pi resellers in the UK for £20.

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.

I believe the GPIO layout changed between v1 and v2 of the Pi Yes, they added 14 more pins to bring it up to 40 pins. Electrically you can still connect the 26-pin cable to the 40-pin header.

The header variant is called the Raspberry Pi Zero WH, which offers a pre-soldered 40-pin GPIO header.

From the Raspberry Pi's specs, to accessories, to cool projects, find out how this $35 mini-PC became the darling makers, hobbyists, and DIY enthusiasts.
