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 ...

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.

What's more, developers can make use of the Raspberry Pi's extra GPIO pins to connect to other devices, electronics and sensors, opening up the field of possibilities for projects even more.

As a leader in the single-board computer space, the company notes that “Raspberry Pi specifications, like our 40-pin GPIO connector and our three-pin debug connector, often become de facto ...

According to the documentation, the communication between the Pi and the RPI2040 nestled beneath the HAT PCB is plaintext-over-serial, freeing up the majority of the GPIO pins for other uses.

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.
