Raspberry Pi 4 Mohlala oa B 
Fetileview
Raspberry Pi 4 Model B ke sehlahisoa sa morao-rao ho likhomphutha tse tummeng tsa Raspberry Pi. E fana ka keketseho e robehang fatše ka lebelo la processor, ts'ebetso ea multimedia, mohopolo le khokahano ha e bapisoa le moloko oa pele oa Raspberry Pi 3 Model B +, ha e ntse e boloka ts'ebelisano ea morao le ts'ebeliso e ts'oanang ea motlakase. Bakeng sa mosebelisi oa ho qetela, Raspberry Pi 4 Model B e fana ka ts'ebetso ea desktop e ka bapisoang le lits'ebetso tsa PC tsa x86.
Likarolo tsa bohlokoa tsa sehlahisoa sena li kenyelletsa ts'ebetso e phahameng ea li-64-bit quad-core processor, tšehetso e bonts'ang liipone ha ho etsoa liqeto ho fihla ho 4K ka likou tse peli tsa HDMI, video ea khomphutha e fihlang ho 4Kp60, ho fihlela 8GB ea RAM, habeli -band 2.4 / 5.0 GHz wireless LAN, Bluetooth 5.0, Gigabit Ethernet, USB 3.0, le bokhoni ba PoE (ka kenyelletso ea PoE HAT e arohaneng).
LAN ea li-wireless-band le Bluetooth li na le setifikeiti sa ho latela melaoana, se lumellang boto hore e entsoe lihlahisoa tsa ho qetela tse nang le liteko tse fokotsitsoeng haholo tsa ho latela, ho ntlafatsa litšenyehelo le nako ea ho e rekisa.
