Shield-ul LCD 20×4 funcționează perfect împreuna cu placa Raspberry PI. Shield-ul se poate conecta direct la portul plăcii sau prin intermediul unei panglici cobbler. 

Placa expune în același timp și toți pinii GPIO ai Raspberry PI (conectorul 2X13, nepopulat, de lângă LCD). În acest mod, poți avea acces la oricare dintre pinii GPIO ai Raspberry PI și în același timp poți folosi și LCD-ul.
