I-Raspberry Pi Foundation Yethula I-Raspberry Pi 3 Model A +

La URaspberry Pi Foundation ukhiphe izindaba ezintsha, ngoba muva nje wethule ukwethulwa kwebhodi elisha, i-Raspberry Pi 3 Model A +.

I-Raspberry Pi 3 Model A + iza nokuqhubeka nokwenziwa kochungechunge oluthi «A». Imodeli ye- "A +" ibekwe njengenguqulo eyenziwe lula futhi ehambisanayo yemodeli ye- "B +".

Lezi zinhlobo ze-Raspberry Pi A zigxile ekusetshenzisweni kwezixazululo ezishumekiwe nezinhlelo ezidinga ukusetshenziswa kwamandla amancane, ezingadingi ukuxhumana kwe-Ethernet kanye nechweba le-USB kuphela.

Yini okusha ku-Raspberry Pi 3 Model A +.

Ukukhishwa kwayo okusha okusanda kumenyezelwa kuthatha iPi 1 Model A + futhi kuyiphakamisela kuma-specs wePi 3, kufaka phakathi iprosesa efanayo ye-64-bit quad-core evalelwe ku-1.4Ghz kanye naku-2.4 / inethiwekhi engenantambo. Imodeli B +.

Ukulandela izinkomba zeModeli A yendabuko, idlula imbobo ye-Ethernet futhi inembobo eyodwa ye-USB esikhundleni sezine ezitholakala ku-B +.

Izici ze-Raspberry Pi Model A + entsha.

• Umseshi : I-Broadcom BCM2837B0, iCorteC-A53 64GHz 1,4-bit SoC
• Memoria : 512MB LPDDR2 SDRAM
• Conectividad : 802.11 GHz ne-2.4 GHz IEE 5.b / g / n / ac LAN engenantambo, i-Bluetooth 4.2 / BLE
• Ukufinyelela : Unhlokweni we-GPIO ongamaphini angama-40
• Ividiyo nomsindo : 1 × usayizi ogcwele we-HDMI
• Imbobo yokubonisa ye-MIPI DSI
• Imbobo yekhamera ye-MIPI CSI
• 4-pole stereo okukhipha futhi esiyinhlanganisela video port
• I-Multimedia: H.264, MPEG-4 (1080p30) yokuhlaziya;
• H.264 (1080p30) ukufaka ikhodi;
• I-OpenGL ES 1.1, ihluzo 2.0
• Isiphathi sekhadi le-SD - Ifomethi ye-Micro SD yokulayisha isistimu yokusebenza nokugcinwa kwedatha
• Amandla wokufaka : 5 V / 2,5 A DC ngesixhumi esincane se-USB 5 V DC ngesihloko se-GPIO
• Imvelo: Ukushisa okusebenzayo, 0-50 ° C.
• Isikhathi sokuphila somkhiqizo: I-Raspberry Pi 3 Model A + izohlala ikhiqizwa kuze kube okungenani ngoJanuwari 2023.

Umehluko kusuka kumodeli 3 B + no-3 A +

Umehluko ekusebenzeni nasekucacisweni kwamandla kungacishe kufane, noma kunjalo Ngokuya ngesethulo, iModeli 3 B + iyona elula kunazo zonke.

Le modeli Iza ne-8GHz ARMv1,4 quad-core processor, i-Wi-Fi, i-Bluetooth, i-Ethernet (i-max 300Mbps), i-USB 2.0 ne-HDMI.

Ngokuqondene ne-Raspberry Pi 3 Model A + entsha kufanele ukuthi ibe imodeli encane, kepha ngezinzuzo eziningi zeModeli B +.

Inokucaciswa okufanayo, Ngaphandle kokuthi uthola u-512MB we-RAM esikhundleni se-1GB, kunembobo eyodwa kuphela ye-USB 2.0 futhi imbobo ye-Ethernet ihambile.

Ngaphezu kwe-CPU esebenza kahle kakhulu engama-64 nokuphinda kabili ubukhulu be-RAM, uphawu lwemodeli entsha ye-A + ukusekelwa okwakhelwe ngaphakathi kwe-wireless 802.11.b / g / n / ac (2.4GHz ne5GHz) ne-Bluetooth 4.2 / BLE.

Izinguquko ze-hardware padding nazo zikhombisa ukusekelwa okuthuthukile kokubhutha kusuka kumadrayivu e-USB nokuphathwa kwamandla okungcono nokulawulwa kwamazinga okushisa (lapho izinga lokushisa kwe-chip lingama-70 °, imvamisa ingu-1.4GHz, kepha uma izinga lokushisa lidlula u-70 °, imvamisa yehlela ku-1.2GHz futhi kumandla we-chip).

Kepha yilokho kuphela.

Uma ungadingi ithani le-RAM noma i-Ethernet, kuyikhompyutha encane ehlonipheke ngokumangazayo.

Noma ngabe uke wadlala nge-Raspberry Pi esikhathini esedlule, amamodeli wakamuva asuka kude. Iprosesa manje inamandla anele okusingatha imisebenzi edingayo.

Impela, kuzothatha isikhathi eside ukudlulisa ividiyo, ukuvula iziphu ifayela elikhulu, noma ukwethula umdlalo olingisiwe ku-Raspberry Pi kunakwilaptop.

Kodwa Uma ufuna ikhompyutha engenamusa esebenzisa i-24/7, kunzima ukuthola okuthile okushibhile. I-Docker isebenza kahle kuyo, ikwenza kube lula ukunakekelwa uma kufakwe ngaphakathi.

Izotholakala nini i-Raspberry Pi 3 A +?

Le modeli entsha emenyezelwe yiRaspberry Pi Foundation Izothengiswa ngoDisemba ngama- $ 25.

Futhi njengokujwayelekile kuzoba nokuxhaswa okuqondile kweRaspbian. Yize bengasebenzisa futhi isikhombimsebenzisi somsebenzisi se-NOOBS ukufaka ukusabalalisa okuhlukile ekhadini le-SD
