Lintlha tsa bohlokoa tsa Raspberry Pi 4B:
Lebelo la ho sebetsa ka potlako:
1. Motlakase oa morao-rao oa Broadcom 2711 quad-core Cortex A72 (ARM V8-A) 64-bit SoC o kentsoeng ho 1.5GHz o ntlafatsa tšebeliso ea matla; le li-thermals ho Pi 4+B li bolela hore CPU e ho BCM2837 SoC e se e ka sebetsa ho 1.5 GHz Eo ke ntlafatso ea 20% ho feta mofuta o fetileng oa Pi 3, o neng o sebetsa ho 1.2GHz.
2. Ts'ebetso ea video ho Pi 4 B e ntlafalitsoe ka ts'ehetso ea li-monitor tse peli ho liqeto ho fihlela 4K ka para ea likou; Hardware video decoding ho fihlela ho 4Kp60, tšehetso bakeng sa H 265 decoding (4kp 60); H.264 le MPEG-4 decoding (1080p60 ).

Waelese ka lebelo:
1. Ha ho bapisoa le mohlala oa pele oa Pi 3, phetoho e kholo ho Pi 4 B ke ho kenyelletsa e ncha, e potlakileng; dual-band wireless chip e tshehetsang 802.11 b/g/n/ac LAN ya waelese.
2. Dual-band 2.4GHz le 5GHz wireless LAN e ts'ehetsa likhokahano tsa marang-rang tse potlakileng ntle le tšitiso e nyane, mme theknoloji e ncha ea antenna ea PCB e ts'ehetsa kamohelo e ntle.
3. 5.0 ea morao-rao e u lumella ho sebelisa keyboard / trackpad e se nang mohala e nang le mefuta e mengata ho feta pele, ntle le li-dongle tse eketsehileng; e boloka lintho li le makhethe.

Khokahano e ntlafalitsoeng ea Ethernet:
1. Pi 4 B e na le marang-rang a marang-rang a potlakileng haholo, ka theknoloji ea USB 3.0; ka lebaka la chip e ntlafalitsoeng ea USB/LAN; o lokela ho bona lebelo ho fihlela makhetlo a 10 ka potlako ho feta mefuta e fetileng ea Pi.
2. Hlooho ea GPIO e lula e tšoana, li-pins tse 40; ka morao e lumellana ka botlalo le liboto tsa bo-mme tse fetileng, joalo ka mefuta e meraro ea pele ea Pi. Leha ho le joalo; ho lokela ho hlokomeloa hore li-plug tse ncha tsa PoE li ka 'na tsa kopana le likarolo tse ka tlaase ho li-caps tse itseng; joalo ka likatiba tsa mookoli.
