Mhuri yemarasipiberi iri kukura
Iyo Raspberry Pi Foundation (www.raspberrypi.org) yakaburitsa yakagadziridzwa vhezheni yeModel B: Model B+. Pakutanga kuona, shanduko dzakaitwa kuB + hadziite senge shanduko. Same SoC (System paChip, BCM2835), huwandu hwakafanana kana rudzi rwe RAM, ichiri isina flash. Uye zvakadaro B + inogadzirisa zvinobudirira matambudziko mazhinji ezuva nezuva anotambudza vashandisi veiyi minicomputer.
Zvinonyanya kukosha ndezvimwe zvekuwedzera USB ports. Nhamba yavo yakawedzera kubva ku2 kusvika ku4. Uyezve, iyo itsva yemagetsi module inofanira kuwedzera kuburitsa kwavo ikozvino kunyange kusvika ku1.2A [1]. Izvi zvinokutendera kuti upe zvakananga magetsi kune mamwe "simba-yakanyanya" zvishandiso, senge ekunze madhiraivha. Imwe shanduko inocherekedza isimbi microSD slot pachinzvimbo chepurasitiki yakazara saizi SD. Pamwe diki, asi muB + kadhi rinenge risingabude kunze kwebhodhi. Izvi zvinonyatso dzikamisa huwandu hwetsaona dzine chekuita nekutyoka slot, netsaona kubvaruka kwekadhi, kana kukuvadzwa kune slot kana yadonha.
Iyo GPIO yekubatanidza yakura: kubva pamakumi maviri nematanhatu kusvika makumi mana mapini. 26 mapini mamwe ekuwedzera epasirese / zvinobuda. Sezvineiwo, iwo maviri mapini ekuwedzera i40c bhazi rakachengeterwa EEPROM ndangariro. Iyo ndangariro ndeyekuchengeta zvigadziriso zvechiteshi kana madhiraivha eLinux. Zvakanaka, zveFlash zvinotora nguva (zvichida kusvika 9 neshanduro 2?).
Yekuwedzera GPIO ports ichauya inobatsira. Kune rimwe divi, zvimwe zvishongedzo zvakagadzirirwa iyo 2 × 13 pini yekubatanidza inogona kunge isingachakwane iyo 2 × 20 yekubatanidza.
Iyo ndiro itsva inewo 4 maburi ekusimudza, zvakanyanya nyore kuparadzaniswa kupfuura maviri ari paB version. Izvi zvichavandudza kugadzikana kwemichina yeRPi-based designs.
Dzimwe shanduko dzinosanganisira kubatanidzwa kweanalog odhiyo jack mune itsva composite 4-pini yekubatanidza. Kubatanidza 3,5 mm audio jack kwairi zvinokutendera kuti uteerere mimhanzi kuburikidza nemahedhifoni kana ekunze matauri.
Nzvimbo yakachengetwa nenzira iyi yakaita kuti zvikwanisike kurongazve bhodhi kuitira kuti pasave nemapulagi akabudikira pamativi ayo maviri. Sekare, USB neEthernet zvakabatanidzwa pamucheto wakafanana. Iyo magetsi, HDMI, composite odhiyo uye vhidhiyo kubuda uye simba plug zvakaendeswa kune yechipiri - yakambo "pararira" kune mamwe mativi matatu. Izvi hazvisi kungofadza chete, asi zvakare zvinoshanda - RPi haichazofanana nemunhu akabatwa newebhu tambo. Izvo zvakaderera ndezvekuti iwe uchafanirwa kuwana imba nyowani.
Iwo ambotaurwa emagetsi matsva anoderedza kushandiswa kwemagetsi neanenge 150 mA. Imwe yekuwedzera magetsi emagetsi emodhiyo module inofanirwa kuvandudza zvakanyanya ruzha (kuderedza huwandu hweruzha).
Mukupedzisa: shanduko hadzisi dzekuchinja, asi dzinoita kuti chikumbiro cheRaspberry Foundation chiwedzere kutaridzika. Miedzo uye tsananguro yakadzama yeiyo B + modhi ichavepo munguva pfupi. Uye mumagazini yaNyamavhuvhu tinogona kuwana yekutanga yeakateedzana zvinyorwa zvinokutendera iwe kuti ufambe zviri nani pasi pe "crimson".
