I-Raspberry Pi Foundation izisa iNew Raspberry Pi 3 Model A +

La I-Raspberry Pi Foundation ikhuphe iindaba ezintsha, kuba kutsha nje utyhile ukuqaliswa kwebhodi entsha, i-Raspberry Pi 3 Model A +.

I-Raspberry Pi 3 Umzekelo A + kuza nokuqhubeka nophuhliso lothotho «A». Imodeli "A +" ibekwe njengohlobo olulula nolucokisekileyo lomzekelo "B +".

Ezi modeli zeRaspberry Pi A zijolise ekusetyenzisweni kwezisombululo ezifakwe ngaphakathi kunye neenkqubo ezifuna ukusetyenziswa kwamandla okuncinci, ezingadingi nxibelelaniso lwe-Ethernet kunye nezibuko le-USB kuphela.

Yintoni entsha kwiRaspberry Pi 3 Model A +.

Ukukhutshwa kwayo kutsha kutsha nje kuthathe iPi 1 Model A + kwaye kuyiphakamisela kwii-specs zePi 3, kubandakanya iprosesa efanayo ye-64-bit quad-core processor evalelwe kwi-1.4Ghz kunye nenethiwekhi ye-2.4 / engenazingcingo. Umzekelo B +.

Ukulandela ii-specs zeModeli yesiko A, ishiya izibuko le-Ethernet kwaye inezibuko elinye le-USB endaweni yezine ezifumaneka kwi-B +.

Iimpawu zohlobo olutsha lweRaspberry Pi Model A +.

• Inkqubo : I-Broadcom BCM2837B0, iCorteC-A53 64GHz 1,4-bit SoC
• Memoria : 512MB LPDDR2 SDRAM
• Conectividad : 802.11 GHz kunye ne-2.4 GHz IEE 5.b / g / n / ac engenantambo ye-LAN, iBluetooth 4.2 / BLE
• Ukufikelela Intloko ye-GPIO engama-40 eyandisiweyo
• Ividiyo kunye nesandi 1 × ubungakanani obupheleleyo be-HDMI
• Izibuko leMIPI DSI
• Ikhamera yekhamera ye-MIPI CSI
• Iziphumo ze stereo ezine-4 kunye nezibuko levidiyo
• Imultimedia: H.264, MPEG-4 (1080p30) ikhowudi;
• H.264 (1080p30) ikhowudi;
• I-OpenGL ES 1.1, imizobo 2.0
• Umnini wekhadi le-SD -Ifomathi ye-Micro SD yokulayisha inkqubo yokusebenza kunye nokugcinwa kwedatha
• Igalelo lamandla : 5 V / 2,5 A DC ngesidibanisi esincinci se-USB 5 V DC ngentloko ye-GPIO
• Indawo esingqongileyo: Ubushushu obusebenzayo, 0-50 ° C.
• Ubomi bemveliso: I-Raspberry Pi 3 Model A + iya kuhlala ikwimveliso kude kube nguJanuwari ngo-2023.

Umahluko ukusuka kwimodeli engu-3 B + no-3 A +

Umahluko ekusebenzeni nasekucacisweni kwamandla kunokuba yinto efanayo, nangona kunjalo Ngokwenkcazo-ntetho, iModeli 3 B + yeyona ilunge kakhulu.

Lo mzekelo Iza ne-8GHz ARMv1,4 quad-core processor, iWi-Fi, iBluetooth, i-Ethernet (ubuninzi be-300Mbps), i-USB 2.0, kunye ne-HDMI.

Ngokuphathelele iRaspberry Pi 3 Model A + entsha kufanele ukuba ibe yimodeli encinci, kodwa uninzi lwezibonelelo zeModeli B +.

Ineenkcukacha ezifanayo, Ngaphandle kokuba ufumana i-512MB ye-RAM endaweni ye-1GB, inye kuphela i-USB 2.0 port kwaye izibuko le-Ethernet lihambile.

Ukongeza kwi-CPU ye-64-bit esebenzayo nokuphindaphinda ubungakanani be-RAM, uphawu lwe-A + entsha yimodeli eyakhelwe-ngaphakathi ye-wireless 802.11.b / g / n / ac (2.4GHz kunye ne5GHz) kunye neBluetooth 4.2 / BLE.

Utshintsho lwezixhobo zehardware zikwabonisa inkxaso ephuculweyo yokuqalisa ngokuqhutywa kwe-USB kunye nolawulo lwamandla olungcono kunye nolawulo lobushushu (xa ubushushu be-chip bungu-70 °, amaza ombane ayi-1.4GHz, kodwa ukuba ubushushu bungaphezulu kwe-70 °, amaza ehla aye kwi-1.2GHz kwaye kwi-chip ombane).

Kodwa yile nto.

Ukuba awuyidingi itoni ye-RAM okanye i-Ethernet, yeyona khomputha intle ngokumangalisayo.

Nokuba ubukhe wadlala ngeRaspberry Pi kwixa elidlulileyo, iimodeli zamva nje zide zavela kude. Iprosesa ngoku inamandla ngokwaneleyo okujongana nemisebenzi enzima.

Ngokuqinisekileyo, kuya kuthatha ixesha elide ukudlulisa ividiyo, ukuvula ifayile enkulu, okanye ukumilisela umdlalo weRaspberry Pi kunelaptop.

Kodwa Ukuba ufuna ikhompyuter engenamdla obaleka i-24/7, kunzima ukufumana into enexabiso eliphantsi. I-Docker isebenza kakuhle kuyo, isenza ukuba kube lula ukuyigcina ukuba ikhonteyina.

Iya kufumaneka nini iRaspberry Pi 3 A +?

Le modeli intsha ibhengezwe yiRaspberry Pi Foundation Iya kuthengiswa ngoDisemba nge-25 yeedola.

Kwaye njengesiqhelo iya kuba nenkxaso yeRaspbian ngqo. Nangona banokusebenzisa ujongano lomsebenzisi we-NOOBS ukufaka ulwahlulo olwahlukileyo kwikhadi le-SD
