Raspberry Pi 4 Muenzaniso B

Overview

Raspberry Pi 4 Model B ndiyo ichangoburwa chigadzirwa mune inozivikanwa Raspberry Pi renji remakomputa. Iyo inopa kuwedzera kwepasi-kutyora muprosesa kumhanya, multimedia kuita, ndangariro, nekubatana zvichienzaniswa neyepamberi-chizvarwa Raspberry Pi 3 Model B +, ichiri kuchengeta kumashure inoenderana uye yakafanana simba rekushandisa. Kune wekupedzisira mushandisi, Raspberry Pi 4 Model B inopa desktop desktop yakafanana neinopinda-chikamu x86 PC masystem.

Aya makiyi ezvigadzirwa anosanganisira epamusoro-kuita 64-bit quad-core processor, mbiri-inoratidzira rutsigiro pazvisarudzo zvinosvika ku4K kuburikidza neyaviri ye Micro-HDMI zviteshi, vhidhiyo dhizaini inosvika kusvika ku4Kp60, inosvika ku8GB ye RAM, mbiri -bhandi 2.4 / 5.0 GHz isina waya LAN, Bluetooth 5.0, Gigabit Ethernet, USB 3.0, uye kugona kwePoE (kuburikidza neakasiyana PoE HAT yekuwedzera).

Iyo mbiri-bhendi isina waya LAN neBluetooth ine modular kutevedzera chitupa, ichibvumira iyo bhodhi kuti igadzirwe muzvigumo zvigadzirwa ine yakanyanya kuderedzwa kuyedza kuteedzera, kugadzirisa zvese mutengo uye nguva kumusika.

Tsanangudzo

processor:
Broadcom BCM2711, quad-musimboti Cortex-A72 (ARM v8) 64-bit SoC @ 1.5GHz

Memory:
1GB, 2GB, 4GB kana 8GB LPDDR4 (zvinoenderana nemodeli) ine-kufa ECC

Kubatana:
2.4 GHz uye 5.0 GHz IEEE 802.11b / g / n / ac wireless LAN, Bluetooth 5.0, BLE
Gigabit Ethernet
2 - USB 3.0 chiteshi
2 - USB 2.0 chiteshi.

GPIO:
Yakajairwa 40-pini GPIO musoro (wakazara kumashure-unoenderana nemabhodhi apfuura)

Vhidhiyo & kurira:
2 --— micro HDMI madoko (anosvika 4Kp60 akatsigira)
2-lane MIPI DSI inoratidzira chiteshi
2-lane MIPI CSI kamera chiteshi
4-pole stereo odhiyo uye inosanganisika vhidhiyo port

Multimedia:
H.265 (4Kp60 kududzira);
H.264 (1080p60 decode, 1080p30 encode);
OpenGL ES, 3.0 mifananidzo

SD kadhi rutsigiro:
Micro SD kadhi slot yekukodha inoshanda sisitimu uye dhata yekuchengetedza

Simba rekuisa
5V DC kuburikidza ne USB-C chinongedzo (mashoma 3A1)
5V DC kuburikidza neGPIO musoro (mashoma 3A1)
Simba pamusoro peEthernet (PoE) "inogoneswa (inoda zvakasiyana PoE HAT)

Environment:
Kushanda kwekushanda 0-50-C

Kutevedzera:
Kune yakazara runyorwa rwemuno nedunhu chigadzirwa zvibvumirano, ndapota shanya https://www.raspberrypi.org/documentation/hardware/raspberrypi/conformity.md

Kugadzirwa kwehupenyu:
Iyo Raspberry Pi 4 Muenzaniso B icharamba iri mukugadzirwa kusvika muna Ndira 2026.

Zvinotaurwa Nezvemuviri

YAMBIRO

Ichi chigadzirwa chinofanirwa kungobatanidzwa kune yekunze magetsi magetsi akatarwa pa5V / 3A DC kana 5.1V / 3A DC minimum1. Chero magetsi ekunze anoshandiswa neRaspberry Pi 4 Model B inotevedzera zvirevo nemitemo inoshanda munyika yekushandisa.
Ichi chigadzirwa chinofanirwa kushanda munzvimbo ine mweya wakanaka uye, kana chikashandiswa mukati mekesi, kesi yacho haifanire kuvharwa.

Ichi chigadzirwa chinofanira kuiswa panzvimbo yakagadzikana, yakati sandara, isingaitisi inoshandiswa mukushandisa uye haifanire kusangana nezvinoitisa zvinhu.
Kubatana kwemidziyo isingaenderane neiyo GPIO yekubatanidza kunogona kukanganisa kutevedzera uye kukonzeresa kukuvara kweyuniti uye kuita kuti waranti isashanda.

Mhedzisiro yese inoshandiswa nechigadzirwa ichi inofanirwa kutevedzera zviyero zvinoenderana nenyika yekushandisa uye inoratidzwa nenzira kwayo kuona kuti chengetedzo pamwe nekuita zvinodiwa zvasangana. Izvi zvinyorwa zvinosanganisira asi hazvingogumiri kumakhibhodi, monitors uye mbeva kana zvichishandiswa pamwe chete neRaspberry Pi.
Panowanikwa nhepfenyuro dzisingasanganise tambo kana chinobatanidza, tambo kana chinongedzo chinofanira kupa kuputira kwakaringana uye mashandiro kuitira kuti kuita kwakakodzera kwekuita uye kuchengetedzeka zvisangane.

KUCHENGETEKA MITIRO

Kuti udzivise kusashanda kana kukuvara kwechigadzirwa ichi ndapota tarisa zvinotevera:

Usafumure kumvura, hunyoro kana nzvimbo pane inoitisa nzvimbo uchiri kushanda.

Usachiisa pachena pakupisa kubva kune chero sosi. Raspberry Pi 4 Model B yakagadzirirwa kuvimbika kushanda pane yakajairwa ambient mukamuri tembiricha.
Chenjerera paunenge uchibata kudzivirira michina kana kukuvara kwemagetsi kune yakadhindwa wedunhu bhodhi uye zvinongedzo.
