Banja la rasipiberi likukula
Raspberry Pi Foundation (www.raspberrypi.org) yatulutsa mtundu waposachedwa wa Model B: Model B+. Poyamba, zosintha zomwe zidapangidwa ku B+ sizikuwoneka ngati zosintha. Same SoC (System on a Chip, BCM2835), kuchuluka komweko kapena mtundu wa RAM, komabe palibe kung'anima. Ndipo komabe B + imathetsa bwino mavuto ambiri atsiku ndi tsiku omwe amazunza ogwiritsa ntchito kompyuta yaying'ono iyi.
Chodziwika kwambiri ndi madoko owonjezera a USB. Chiwerengero chawo chawonjezeka kuchokera ku 2 mpaka 4. Komanso, gawo latsopano la mphamvu liyenera kuonjezera zomwe zikuchitika panopa mpaka 1.2A [1]. Izi zikuthandizani kuti mupereke mphamvu mwachindunji kuzipangizo "zowonjezera mphamvu", monga ma drive akunja. Kusintha kwina kodziwika ndi kagawo kakang'ono kachitsulo ka microSD m'malo mwa pulasitiki ya SD yokwanira. Mwina pang'ono, koma mu B + khadi pafupifupi silimatuluka kupitirira bolodi. Izi zidzachepetsa chiwerengero cha ngozi zomwe zimagwirizanitsidwa ndi slot yosweka, kung'ambika mwangozi khadi, kapena kuwonongeka kwa slot pamene wagwetsedwa.
Cholumikizira cha GPIO chakula: kuchokera pa 26 mpaka 40 mapini. 9 pini ndizowonjezera / zotulutsa zapadziko lonse lapansi. Chosangalatsa ndichakuti mapini awiri owonjezerawa ndi basi ya i2c yosungidwa kukumbukira kwa EEPROM. Memory ndikusunga masinthidwe adoko kapena madalaivala a Linux. Chabwino, kwa Flash idzatenga nthawi (mwina mpaka 2017 ndi mtundu 2.0?).
Madoko owonjezera a GPIO adzakhala othandiza. Kumbali inayi, zida zina zopangira cholumikizira cha 2 × 13 sizingafanane ndi cholumikizira cha 2 × 20.
Mbale yatsopanoyi imakhalanso ndi mabowo okwera 4, osavuta kwambiri kusiyana ndi awiri omwe ali pa mtundu wa B. Izi zidzakulitsa kukhazikika kwa makina a RPi-based designs.
Zosintha zina zikuphatikiza kuphatikiza kwa jack audio ya analogi kukhala cholumikizira chatsopano cha pini 4. Kulumikiza jack audio ya 3,5 mm kumakupatsani mwayi womvera nyimbo kudzera pa mahedifoni kapena oyankhula akunja.
Danga losungidwa motere linapangitsa kuti zitheke kukonzanso bolodi kuti pasakhale mapulagi otuluka kumbali zake ziwiri. Monga kale, USB ndi Efaneti ali m'magulu a m'mphepete chomwecho. Mphamvu zamagetsi, HDMI, zomvera zophatikizika ndi makanema komanso pulagi yamagetsi idasunthidwa kupita yachiwiri - "yobalalika" mbali zina za 3. Izi sizongosangalatsa zokhazokha, komanso zothandiza - RPi sidzakhalanso ngati munthu wovutitsidwa ndi ukonde wa zingwe. Choyipa chake ndikuti muyenera kupeza nyumba zatsopano.
Mphamvu zatsopano zomwe zatchulidwazi zichepetsa kugwiritsa ntchito mphamvu pafupifupi 150 mA. Chigawo chowonjezera chamagetsi cha module ya audio chiyenera kukweza kwambiri phokoso (kuchepetsa phokoso).
Pomaliza: zosintha sizosintha, koma zimapangitsa lingaliro la Raspberry Foundation kukhala lokongola kwambiri. Mayesero ndi kufotokozera mwatsatanetsatane za mtundu wa B + zidzapezeka posachedwa. Ndipo m'magazini ya Ogasiti titha kupeza zolemba zoyambirira zomwe zingakuthandizeni kuyendetsa bwino dziko "lofiira".
