The RasPiO® Portsplus board is designed for the new Raspberry Pi 2/A+/B+. It labels the ports clearly for you so that you don’t need to count pins. This will help you avoid wiring errors and damage.
You can slip it over the GPIO header if you want, or hold it next to the header (many people tell me they do this – and this approach will also work for the older models A/B).
RasPiO® Portsplus has GPIO port numbers on one side and Pin numbers on the other side, so you can use whichever numbering system you prefer.
You can use it as an attractive key-fob as well (split-ring not supplied). At just 1mm thick, it leaves plenty of space for attaching your wires. It’s thick enough not to feel flimsy, but thin enough not to be clunky.
*Please Note* Raspberry Pi and Split-Ring not included
