ʻO Raspberry Pi 4 Model B ka huahana hou loa i ka laulā Raspberry Pi kaulana o nā kamepiula. Hāʻawi ia i ka piʻi ʻana o ka honua i ka wikiwiki o ka processor, ka hana multimedia, ka hoʻomanaʻo, a me ka pilina e hoʻohālikelike ʻia i ka hanauna mua
ʻO Raspberry Pi 3 Model B+, ʻoiai e mālama ana i ka hoʻohālikelike ʻana i hope a me ka hoʻohana mana like. No ka mea hoʻohana hope, hāʻawi ʻo Raspberry Pi 4 Model B i ka hana pākaukau e like me nā ʻōnaehana PC x86 pae komo.
ʻO nā hiʻohiʻona nui o kēia huahana me kahi 64-bit quad-core unu lawelawe kiʻekiʻe, kākoʻo pālua i nā hoʻonā a hiki i ka 4K ma o nā ʻāpana micro-HDMI port, hoʻopau wikiō wikiō ma 4Kp60, a i 8GB RAM, pālua. -band 2.4 / 5.0 GHz pūnaewele LAN, Bluetooth 5.0, Gigabit Ethernet, USB 3.0, a me ka hiki PoE (ma o ka hoʻohui PoE HAT ʻokoʻa).
Loaʻa i ka LAN-Bluetooth a me ka Bluetooth nā palapala hōʻoia pono kaulike, e ʻae ʻia e hoʻolālā i ka papa i nā huahana hopena me ka hoʻoliʻiliʻi hoʻoliʻiliʻi hoʻāʻo, e hoʻomaikaʻi ana i nā kumukūʻai a me ka manawa e kūʻai.

| Mea hana: | Broadcom BCM2711, quad-core Cortex-A72 (ARM v8) 64-bit SoC @ 1.5GHz |
| Hoʻomanaʻo: | 2GB, 4GB a i ʻole 8GB LPDDR4 (ma muli o ke kumu hoʻohālike) |
| Hoʻohui | 2.4 GHz a me 5.0 GHz IEEE 802.11b/g/n/ac uila LAN, Bluetooth 5.0, BLE Gigabit Ethernet 2 × USB 3.0 awa 2 × USB 2.0 awa. |
| GPIO: | ʻO ke poʻo poʻomanaʻo GPIO 40-pin GPIO (kū hope loa i ke kūlike me nā papa i hala) |
| wikiō & kani: | 2 × micro HDMI awa (a hiki i 4Kp60 kākoʻo) 2-lane MIPI DSI hōʻike awa 2-alanui MIPI CSI awa pahupaʻiwikiō 4-pahu stereo leo leo a me ke awa wikiō paʻa |
| Multimedia: | H.265 (4Kp60 decode); H.264 (1080p60 decode, 1080p30 encode); OpenGL ES, 3.0 kiʻi |
| Kākoʻo kāleka SD: | Kāleka Micro SD no ka hoʻouka ʻana i ka ʻōnaehana hana a me ka mālama ʻikepili |
| Mana hookomo: | 5V DC ma o ka mea hoʻohui USB-C (ka liʻiliʻi 3A 1 ) 5V DC ma o ke poʻomanaʻo GPIO (ka liʻiliʻi 3A1) Mana ma luna o Ethernet (PoE)–hoʻā (koi i ka PoE HAT kaʻawale) |
| Kaiapuni: | ʻO ka mahana hana 0–50ºC |
| Hoʻokō: | No kahi papa inoa piha o nā ʻae a me nā huahana kūloko, e ʻoluʻolu e kipa https://www.raspberrypi.org/documentation/hardware/raspberrypi/conformity.md |
| Iecaianoaaiiuo ola: | E noho ka Raspberry Pi 4 Model B i ka hana a i ka manawa ma Ianuali 2026. |

Pono e hoʻopili wale ʻia kēia huahana i kahi lako mana waho i helu ʻia ma 5V/3A DC a i ʻole 5.1V/3A DC ka liʻiliʻi. hoʻohana.
- Pono e hoʻohana i kēia huahana i kahi lewa pono a, inā hoʻohana ʻia i loko o kahi hihia, ʻaʻole pono e uhi ʻia ka hihia.
- Pono e kau i kēia huahana ma luna o kahi paʻa, pālahalaha, a me nā ʻano alakaʻi ʻole i hoʻohana ʻia a pono ʻole e hoʻopili ʻia e nā mea conductive.
- ʻO ka pilina o nā hāmeʻa i kūlike ʻole i ka pilina GPIO e hoʻopili i ka mālama ʻana a hopena i ka hōʻino ʻana i ka ʻāpana a hōʻole ʻole i ka palapala hoʻokō.
- Pono nā peripherals āpau i hoʻohana ʻia me kēia huahana e kūlike me nā kūlana kūpono no ka ʻāina o ka hoʻohana a e kaha ʻia e like me ka hōʻoia ʻana e hoʻokō ʻia nā koi palekana a me nā hana. Hoʻopili kēia mau ʻatikala akā ʻaʻole kau palena ʻia i nā papapihi, nā mākaʻi a me nāʻiole ke hoʻohana pū ʻia me ka Raspberry Pi.
- Ma kahi e pili ai nā peripherals ʻaʻole i hoʻokomo i ke kaula uea a i ʻole nā mea hoʻopili, pono i ke kaula uea a i ʻole nā mea hoʻopili e hāʻawi i kahi insulation kūpono a me ka hana i hiki ai ke hoʻokō ʻia nā hana e pili ana a me nā palekana.

I mea e hōʻalo ai i nā hana maikaʻi ʻole a hōʻino paha i kēia huahana e nānā i kēia mau mea:
- Mai hōʻike i ka wai, onaona a i ʻole kau ma kahi ʻili conductive ʻoiai e hana ana.
- Mai hōʻike iā ia i ka wela mai kekahi kumu; Hoʻolālā ʻia ʻo Raspberry Pi 4 Model B no ka hana pono i ka mahana maʻamau o nā lumi.
- Mālama i ka lawelawe ʻana e hōʻalo i ka hōʻino mechanical a uila paha i ka papa kaapuni i paʻi ʻia a me nā mea hoʻopili.
- E hōʻalo i ka lawelawe ʻana i ka papa kaapuni i paʻi ʻia ʻoiai e hoʻohana ʻia ana a mālama wale ʻia e nā ʻaoʻao e hōʻemi i ka hopena o ka pōʻino o ka hoʻokuʻu electrostatic.
Hiki ke hoʻohana ʻia kahi mana 2.5A maikaʻi maikaʻi inā hoʻopau nā peripheral USB ma lalo o 500mA i ka nui.
