I-Raspberry Pi 5: i-SBC okudala ilindelwe isifikile, nokusebenza okwengeziwe nosayizi ofanayo

I-Rasperry Pi 5

Isikhathi eside silindile kusukela ekukhululweni Ukusajingijolo Pi 4 kuze kube iRaspberry Pi Foundation isikhiphe esikhundleni, i-Raspberry Pi 5 entsha efika ngo-2023. Futhi isifikile inezici ezintsha ezithakazelisa kakhulu esizokutshela ngazo, ngaphezu kokusebenza okwengeziwe kunokwandulelayo nosayizi ofanayo.

Kodwa-ke, mina mathupha ngicabanga ukuthi bengingathanda okwengeziwe ukube i-CPU ibisekelwe ku-RISC-V ISA evulekile, hhayi ku-ARM ISA evaliwe. Ngaphezu kwalokho, lokhu bekungabazuzisa kakhulu I-RISC-V ecosystem, njengoba onjiniyela abaningi bangaba nentshisekelo kule nkundla, futhi bangahlanganisa futhi bapakishe isofthiwe eyengeziwe... Nokho, lokhu akuzange kube njalo...

Ukutholakala Ukuphela kuka-Okthoba

Ukuhlaziywa kwezici ezintsha ze-SBC Raspberry Pi 5

Ukusajingijolo Pi 5

Manje sizokwephula lokho okuvezwa yile Raspberry Pi 5, sigqamisa izinzuzo zayo kanye nokubi:

Izindaba ze-chip

El I-SoC entsha ehlanganisiwe yi-Broadcom BCM2712, ekhiqizwa yi-TSMC ene-16 nm node. Le chip imelela ukuthuthuka okuphawulekayo kunomanduleli wayo, enikeza ukusebenza kwe-CPU okungafika ku-2x okukhulu kwezinye izimo. Khumbula ukuthi i-4 Pi 2019 yayine-72 GHz ARM Cortex-A1,5 quad-core SoC (esheshiselwe ku-1,8 GHz), kuyilapho i-Raspberry Pi 5 entsha isebenzisa i-quad-core chip nayo, kodwa kulokhu inama-cores ARM Cortex-A76 2,4 GHz Naphezu kwalokhu, ukusetshenziswa kuhlala kungaphakathi kwemingcele ehloniphekile, kukhuphuka kusuka ku-8W ku-Pi 4 kuya ku-12W ku-Pi 5.

Ngakolunye uhlangothi, uhlelo oluncane lokufakwayo nokukhiphayo manje seluzoba nalo umkhawulokudonsa ophezulu. Lokhu kuzovumela i-Raspberry Pi 5 ukuthi ixhume ngqo kuziqaphi ezimbili ze-4K @ 60 FPS ngenxa ye-GPU entsha, futhi izophinda ibe nomkhawulokudonsa ophindwe kabili wamachweba we-USB 3.0. Futhi lokho akusho ukuthi i-SoC iphinde ibe nomzila we-PCIe wokuxhuma ama-peripherals alolu hlobo, njenge-NVMe M.2 SSD yesitoreji semidiya ku-PCIe 2.0 x1.

U-Eben Upton, umholi wephrojekthi, oqokonyiswe ikakhulukazi kulokhu kwethulwa I-SoC RP1 iklanywe i-Raspberry Pi Foundation futhi yakhiqizwa i-TSMC ene-node 40LP, eklanywe ngokukhethekile ithimba elifanayo ne-RP2040 microcontroller. Le chip, lapho isisekelo sitshale khona amadola ayizigidi ezingu-15 ukuze ithuthukiswe, inesibopho sokuthuthukisa umkhawulokudonsa ezindaweni ezihlukahlukene zokufaka nokukhiphayo, njengezimbobo ze-USB 3.0, izimbobo ze-Ethernet, isixhumi esibonakalayo se-GPIO kanye nemiphumela. Ikhamera nesibonisi I-MIPI, okwenza kube lula ukuxhuma amakhamera ewebhu noma izikrini zokuthinta ezincane ku-Raspberry Pi. Le chip manje isizoba nomthwalo wemfanelo wokuphatha isixhumi esibonakalayo samakhadi e-SD, kanye nokuxhumana ne-SDRAM, ehlinzeka ngokuphindwe kabili kwe-MT/s kunokwandulelayo.

I-adaptha yokuxhuma okungenantambo ehlanganisiwe ingaxhunywa nge I-WiFi 5, ne-Bluetooth 5.0 (ene-BLE), akukubi neze, kodwa kuyiqiniso ukuthi kunezimiso zokuxhumana ezithuthuke kakhulu, njenge-WiFi 6 ne-6E, noma i-Bluetooth 5.3, esingeke sikwazi ukuyijabulela kule SBC entsha. Kunjalo, uma sishintshana sinentuthuko ethile yokunciphisa ukusetshenziswa kwamandla kwale chip nokuthuthukisa ukusebenza kwayo.

Ukuphatha ukondla nakho kwenziwe ngcono nge i-chip entsha ye-Renesas okuvumela ukuhlinzeka kufika ku-20A wamanje ukuze kunikwe amandla ama-cores amasha nokuqinisekisa ukusebenza kahle, ngaphezu kokunika amandla amanye amasistimu e-SBC nama-peripheral axhunywe kuyo.

I-SBC Design

El idizayini entsha ye-PCB Ifana namapuleti e-SBC angaphambilini alesi sisekelo, agcina ngaphezulu noma ngaphansi kwefomethi efanayo nosayizi. Kukhona izinguquko ezithile, noma kunjalo, njengokususwa kwezixhumi zevidiyo ezihlanganisiwe, ezisatholakala ngesixhumi esincane esikhethekile ebhodini, kanye nokususwa kwembobo ye-headphone.

Ngakolunye uhlangothi, zifakiwe izixhumi ezimbili ze-FPC esebenza njengezindawo zokusebenzelana ze-MIPI enamathrekhi amane, okuvumela ukuxhumeka kwamakhamera nezibonisi. Ngenkathi isixhumi se-Gigabit Ethernet sibuyele endaweni yaso yasekuqaleni, ekhoneni elingezansi kwesokudla sebhodi, okungukuthi, ukubuyisela emuva isikhundla esasinaso kumodeli ye-Raspberry Pi 4. Ngaphezu kwalokho, isixhumi samandla phezu kwe-Ethernet (PoE) sengeziwe. amaphini amane, avumela amandla ngekhebuli yenethiwekhi ngokwayo (RJ-45).

Le plate futhi ihlanganisa izimbobo ukuvumela abasebenzisi ingafaka ama-heatsink noma abalandeli ye-SoC eyinhloko, futhi ngaleyo ndlela ipholise iyunithi uma ifuna ukuyicindezela kakhulu. Into eyenzeka nakwabandulelayo.

Ngaphezu kwalokho, izici ezicelwe kakhulu zifakiwe, njengewashi lesikhathi sangempela elinganikwa amandla ibhethri le-lithium-manganese elishajekayo noma i-supercapacitor yangaphandle, kanye nenkinobho yokuvula/ukuvala esekela kokubili. ukuvala shaqa kanzima (kanzima) njengokuvala shaqa okuthambile (okuthambile), ngaphezu kwemicimbi yokuthungela. Ngaphandle kokungabaza okuthile okufanele ngabe bakwenzile kusukela kushicilelo lokuqala lwe-SBC...

Izesekeli

Phakathi kwe izesekeli ezitholakalayo ze-Raspberry Pi 5, sinokulandelayo (yize okuningi kuzofika okuvela ezinkampanini zangaphandle):

  • Ibhokisi elisha, elisekelwe ekwakhiweni kwedlule, kanye nezikhala zokukhipha ukushisa.
  • I-Heatsink/ifeni yokupholisa, inenani elingu-$10 lesistimu yokupholisa esebenzayo (enefeni) noma u-$5 kuleyo engenziwa lutho (usinki kuphela).
  • Ikhebuli yamandla entsha engu-27W.
  • Amakhebula amakhamera nezikrini.
  • I-PoE+ Hat, yamandla phezu kwentambo ye-Gigabit Ethernet LAN (RJ-45).
  • Izixhumi zokusetshenziswa kwe-NVMe SSD nezinye izesekeli ze-M.2.
  • Ibhethri ye-lithium yokugcina i-RTC lapho i-SBC ivaliwe.

Uhlelo lokusebenza kanye nesoftware

Futhi, ekugcineni, ayikho i-hardware entsha kuphela, i-Raspberry Pi 5 izophinde ibe nezici ezintsha zesofthiwe. I-Raspberry Pi Foundation isimemezele ukwethulwa kwe- i-Raspberry Pi OS entsha (ngaphambilini ebibizwa nge-Raspbian OS) ebizwa ngokuthi "Bookworm". Lolu hlelo lokusebenza olusemthethweni lwe-Raspberry Pi, olusekelwe ku-Debian 12, luzofaka ukuthuthuka okufana noshintsho olusuka kuhlelo lwe-X11 lwe-graphics server luye ku-Wayfire Wayland, futhi luzosekela kokubili i-Pi 4 kanye ne-Pi 5, ngakho-ke uma une-Pi 4 futhi. ungakuzama...
