Raspberry Pi -säätiö julkaisi marraskuussa 2015 erittäin pienen ja edullisen version kortistaan. Se sai nimekseen Zero. Nyt säätiö on tuonut Zerolle tuen niin WiFi- kuin bluetooth-yhteyksille. Hinta on edelleen pieni eli 10 dollaria.

Radiomoduulin lisääminen Zero-kortille ei ehkä ole maailman suurin tekninen innovaatio, mutta kehittäjien kannalta kyse on tärkeästä uudistuksesta. Tähän asti Zeron on saanut liittää langattomiin verkkoihin erillisten mokkuloiden avulla.

Uusi Zero W -versio on sanaut sisuksiinsa Cypressin CYW43438-radiopiirin, joka tuo langattomat yhteydet myös Raspberry Pin suuremmalle 3 Model B -kortille. Muut yhteydet ovat ennallaan: Mini-HDMI ja kaksi Micro-USB-liitäntää.

Zero-korttien etuna on se, että pienestä koosta ja hinnasta huolimatta niillä on varsin kohtuullisesti suorituskykyä. Broadcommin prosessori yltää gigahertsin kellotaajuuteen ja työmuistia on 512 megatavua.
