Tauira B
I whakaputaina i Mei 2020 e Raspberry Pi Trading Ltd. www.kawera.org
Ka mutuview
Ko te Raspberry Pi 4 Model B te hua hou i roto i nga momo rorohiko rongonui a Raspberry Pi. Ka whakaekea e ia nga piki o te tere o te tukatuka, te mahi rongorau, te mahara, me te honohono ki te reanga o mua
Raspberry Pi 3 Tauira B+, i te wa e mau tonu ana te hototahi whakamuri me te kohi hiko rite. Mo te kaiwhakamahi mutunga, ko te Raspberry Pi 4 Model B e whakarato ana i nga mahi papamahi e rite ana ki nga punaha PC x86 taumata-urunga.
Ko nga waahanga matua o tenei hua ko te tukatuka 64-bit tapawha-nui, he tautoko rua-whakaaturanga i nga whakataunga tae atu ki te 4K ma nga tauranga micro-HDMI e rua, te whakaheke i te riipene ataata taputapu tae atu ki te 4Kp60, tae atu ki te 8GB o RAM, takirua. -inaa 2.4 / 5.0 GHz ahokore LAN, Nihokikorangi 5.0, Gigabit Ethernet, USB 3.0, me te kaha PoE (na roto i te taapiri motuhake PoE HAT).
Ko te LAN ahokore-roopu koreutu me te Nihokikorangi he tiwhikete whaawhaiti takawaenga, ka ahei te poari ki te hoahoahia me nga hua mutunga ki te tino whakaiti i te whakamatautau ture, me te whakapai ake i te utu me te wa ki te maakete.

Whakatakotoranga Tinana
WHAKATOKANGA
Me hono noa tenei hua ki tetahi hiko o waho kua whakatauhia ki te 5V/3A DC, 5.1V/3A DC te iti rawa Ko nga taputapu hiko o waho e whakamahia ana me te Raspberry Pi 4 Tauira B me ū ki nga ture e tika ana me nga paerewa e pa ana ki te whenua e whakaarohia ana. whakamahi.
- Ko tenei hua me whakahaere i roto i te taiao tino pai te hau, ana ki te whakamahia i roto i tetahi keehi, kaua e kapi te keehi.
- Ko tenei hua me whakanoho ki runga i te papa, papatahi, kore-arahi hei whakamahi me te kore e whakapiri atu ki nga taonga kawe.
- Ko te honohono o nga taputapu hotokore ki te hononga GPIO ka pa ki te whakatutukitanga ka pa ki te kino o te waahanga ka kore e whakamanahia te raihana.
- Katoa nga taputapu e whakamahia ana me tenei hua me hangai ki nga paerewa whaitake mo te whenua whakamahi ka tohua kia pai ai te whakatutukitanga o nga whakaritenga haumaru Kei roto i enei tuhinga engari kaore e whaaitihia ki nga papapātuhi, nga kaitirotiro me nga kiore ina whakamahia ana me te Raspberry Pi.
- Ka honoa nga piringa kaore i te whakauru i te taura, te honohono ranei, me tuku e te taura, hononga ranei te tika o te whakawehiwehi me te whakahaere kia tutuki ai nga whakaritenga e pa ana me nga whakaritenga haumaru.
NGĀ TOHUTOHU HAURAU
Kia kore ai e he te mahi, kia kino ranei tenei hua tirohia enei e whai ake nei:
- Kaua e whakaatuhia ki te wai, ki te houku, ki te waahi ranei e whakahaere ana i te waa whakahaere i a koe.
- Kaua e tukuna ki te wera mai i tetahi atu puna; Raspberry Pi 4 Tauira B kua hoahoatia mo te mahi pono i te paahana o te ruuma o te ruuma.
- Kia tupato i a koe e whakahaere ana kia kore e kino te miihini, te hiko ranei ki te papa hiko iahiko me nga hononga.
- A ape i te whakahaere i te papa taiawhio i te wa e hiko ana, ka hapai noa i nga taha ki te whakaiti i te tupono o te tukunga hiko.
Ka taea te whakamahi i te mana mana 2.5A tino pai mena ka iti ake i te 500mA te kohinga o nga riu USB o raro.
Ko te HDMI®, te tohu HDMI®, me te Atanga Whakamaramatanga Whakaata Nui he tohu hokohoko, he tohu rehita ranei o HDMI® Licensing LLC.
Ko MIPI DSI me MIPI CSI nga tohu ratonga na MIPI Alliance, Inc.
Ko te Raspberry Pi me te tohu Raspberry Pi he tohu hokohoko na te Raspberry Pi Foundation. www.kawera.org
