Raspberry Pi 4 Computer
Muenzaniso B
Rakadhindwa muna Chivabvu 2020 naRaspberry Pi Trading Ltd. www.raspberrypi.org
Overview
Raspberry Pi 4 Model B ndiyo yazvino chigadzirwa mune yakakurumbira Raspberry Pi mhando yemakomputa. Inopa kuwedzera-kupwanya kuwedzera mukumhanyisa processor, kuita multimedia, ndangariro, uye yekubatanidza kana ichienzaniswa neyekutanga-chizvarwa.
Raspberry Pi 3 Model B +, uchichengeta kumashure kuenderana uye yakafanana mashandisiro emagetsi. Kune yekupedzisira-mushandisi, Raspberry Pi 4 Model B inopa desktop performance inofananidzwa neyekupinda-level x86 PC masisitimu.
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.

Zvinotaurwa Nezvemuviri
YAMBIRO
Ichi chigadzirwa chinofanirwa kunge chakabatana nekunze kwemagetsi akaiswa pa5V/3A DC kana 5.1V/3A DC shoma Chero magetsi ekunze anoshandiswa neRaspberry Pi 4 Model B anoteera mirau uye zviyero zvinoshanda munyika yakatarwa. use.
- 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.
- Regedza kubata bhodhi redunhu rakadhindwa riine simba uye rinongobata nemucheto kuderedza njodzi yekukuvara kwemagetsi.
Yakanaka mhando ye2.5A magetsi anogona kushandiswa kana pasi pemvura USB peripherals inoshandisa isingasviki 500mA yakazara.
