Eben Upton, muvambi weRaspberry Pi akafumurwa munguva pfupi yapfuura iyo Raspberry Pi Zero 2W Iyo inouya ne 1GHZ processor iyo, sekureva kwemugadziri, inopa 5 times more performance for multithreaded workloads pane Raspberry Pi Zero kubva 2015.
Iyo itsva Raspberry Pi Zero 2W inounzawo Arm cores zvishoma zvishoma kusvika ku1GHz, 512MB yeLPDDR2 SDRAM yakasungirirwa mune imwe kabati inochengetedza nzvimbo yemadhora gumi nemashanu.
Kune avo vasina kujairana neRaspberry Pi, iwe unofanirwa kuziva kuti iyi ikiredhiti kadhi-saizi ARM processor komputa imwe chete yebhodhi yakagadzirwa nemapurofesa kubva kubazi reComputer Science paYunivhesiti yeCambridge sechikamu cheRaspberry Pi Foundation.
Yakagadzirwa kuti iite democratize kuwana makomputa uye kusikwa kwedhijitari. Iyo Raspberry Pi inobvumira kuitwa kweakasiyana akasiyana emahara GNU / Linux anoshanda system, kunyanya Debian, uye inoenderana software.
Nezve iyo itsva Raspberry Pi Zero 2W
Inotengeswa pamadhora gumi nemashanu, iyo Raspberry Pi Zero 15W inoshandisa yakafanana Broadcom BCM2A2710 SoC chip. kupfuura shanduro yekusunungurwa yeRaspberry Pi 3. Kuwedzera kwekuita kwepamusoro pamusoro peZero kunosiyana nemabasa akawanda, asi kune sysbench yakawanda-yakagadzirwa, inenge yakanyatsoita kashanu nokukurumidza.
Nezve hunhu yeRaspberry Pi Zero 2W ndeyotevera:
- Mini HDMI port
- 512MB LPDDR2 SDRAM
- CSI-2 kamera yekubatanidza
- 1 × USB 2.0 interface ine OTG
- Graphics OpenGL ES 1.1, 2.0
- 40-pini HAT inoenderana I / O
- MicroSD kadhi slot
- 2,4 GHz 802.11 b / g / n WiFi, Bluetooth 4.2, BLE
- H.264, MPEG-4 (1080p30) decoding; H.264 (1080p30) encoding
- Broadcom BCM2710A1, 64-bit Quad Core SoC (53 GHz Arm Cortex-A1)
- Composite vhidhiyo solder mapoinzi uye reset pini.
Raspberry Pi mainjiniya Simon Martin, akagadzira iyo Zero 2W uye RP3A0 bhokisi rinoripa simba, akakwanisa kudzvanya iyo yese yekuwedzera kuita muZero yekutanga fomu chinhu.
Icho chipingamupinyi chikuru chekugadzira inokwanisa Raspberry Pi Zero yagara iri iyo fomu chinhu-Iine bhodhi diki uye imwe-sided chikamu chekuiswa, hapana nzvimbo yemuviri yekugadzika ese makuru masisitimu pane chip (SoC) uye discrete SDRAM.
Kufanana neRaspberry Pi 1, iyo Raspberry Pi Zero uye Zero W yakavakirwa paBroadcom BCM2835 SoC. Iyo yekupedzisira inodzivirira dambudziko nekushandisa PoP (packet pamusoro pepakiti) tekinoroji, umo iyo SDRAM bhokisi inogara zvakananga pamusoro peSoC.
PoP mhinduro inoyevedza kana iyo SoC's silicon chip idiki zvekukwana mugomba pakati peyepamusoro kesi yeSDRAM. Nehurombo, Broadcom payakawedzera Quad Cortex-A7 (kugadzira iyo BCM2836), kozoti Quad Cortex-A53 (kugadzira iyo BCM2837), iyo chip yakapfuura nepaPoP mhango.
Thermal inonetsa kana uchirongedza kuita kwakawanda mupakeji diki - kupisa kunogadzirwa sei neanokurumidza processor kubviswa? Kufanana nezvimwe zvichangobva kuitika zveRaspberry Pi zvigadzirwa, iyo Zero 2W inoshandisa gobvu yemukati memhangura maseru kubvisa kupisa kubva kune processor. Kana iwe uine Zero W uye Zero 2 W mumaoko ako, unogona kunyatsonzwa mutsauko mukurema.
Kusvika pari zvino, kutengesa kwakangotanga muUK, European Union, US, Canada neHong Kong; Kuendesa kune dzimwe nyika kunozovhurwa kana iyo isina waya module inosimbiswa. Mutengo weRaspberry Pi Zero 2 W imadhora gumi nemashanu (yekuenzanisa, mutengo weRaspberry Pi Zero W bhodhi imadhora gumi uye Raspberry Pi Zero imadhora mashanu, kugadzirwa kwemabhodhi akachipa kuchaenderera mberi) .
Kana iwe uchida kuziva zvakawanda nezvazvo, unogona kutarisa iyo ruzivo mune inotevera chinongedzo.
Pakupedzisira, tIzvo zvakakoshawo kuratidza kusimudzira kweRaspberry Pi kwakaziviswawo una itsva yepamutemo USB simba rekupa kuperekedza iyo Zero 2 W.
Inotaridzika zvakanyanya senge Raspberry Pi 4 magetsi, asi ine USB micro-B yekubatanidza panzvimbo ye USB yekubatanidza. C, uye ine peak ikozvino yakaderedzwa zvishoma kusvika 2.5A. Inobatsira kwazvo kana iwe uchida kupa simba Raspberry Pi 3B kana 3B +.
Simba rekushandisa rinowanikwa nemhando dzinotevera dzemapulagi: United States neCanada (rudzi rweA); Europe (rudzi C); India (rudzi D); United Kingdom (rudzi rweG); uye Australia, New Zealand neChina (rudzi I).
