Raspberry Pi projekt teatas, et m\u00fc\u00fcki on tulnud uue p\u00f5lvkonna Raspberry Pi Zero W plaat, mis \u00fchendab endas kompaktsed m\u00f5\u00f5tmed ja toetuse Bluetoothile ning Wi-Fi-le. Uus mudel Raspberry Pi Zero 2 W on valmistatud samas miniatuurses formaadis (65 x 30 x 5 mm), st umbes kaks korda v\u00e4iksem kui tavaline Raspberry Pi. Praegu on m\u00fc\u00fck alanud vaid Suurbritannias, Euroopa Liidus, Ameerika \u00dchendriikides, Kanadas ja Hongkongis; tarned teistesse riikidesse avatakse p\u00e4rast traadita moduli sertifitseerimise l\u00e4bimist. Raspberry Pi Zero 2 W hind on 15 USA dollarit (kui v\u00f5rrelda, siis Raspberry Pi Zero W hind on 10 dollarit ja Raspberry Pi Zero hind on 5 dollarit; odavamatel plaatidel j\u00e4tkatakse tootmist).

\"Esimene<\/center> <\/p>\n

Raspberry Pi Zero uue mudeli peamine erinevus on \u00fcleminek SoC Broadcom BCM2710A1-le, mis on sarnane Raspberry Pi 3-l kasutatavaga (eelmises p\u00f5lvkonnas kasutati Zero plaatidel SoC Broadcom BCM2835, nagu esimeses Raspberry Pi-s). Erinevalt Raspberry Pi 3-st on protsessori sagedus energiat\u00f5hususe suurendamiseks v\u00e4henenud 1,4 GHz-lt 1 GHz-le. Sysbench'i multimeetodilise testi p\u00f5hjal on SoC uuendamine v\u00f5imaldanud plaadi j\u00f5udlust t\u00f5sta viis korda (uus SoC kasutab neljatuumalist 64-bitist CPU Arm Cortex-A53 asemel \u00fchetuumalist 32-bitist ARM11 ARM1176JZF-S). <\/p>\n

Nagu eelmises versioonis, pakub Raspberry Pi Zero 2 W 512 MB RAM-i, Mini-HDMI porti, kahte Micro-USB porti (USB 2.0 OTG ja toiteport), microSD pesat, 40-pin GPIO liidest (millel pole jootmist), komposiitvideo ja kaamera v\u00e4ljundeid (CSI-2). Plaat on varustatud traadita kiibiga, mis toetab Wi-Fi 802.11 b\/g\/n (2,4 GHz), Bluetooth 4.2 ja Bluetooth Low Energy (BLE). Uuel plaadil on traadita kiip kaetud metalls\u00fcdamikuga, et tagada FCC sertifitseerimine ja kaitse v\u00e4liste h\u00e4irete eest. <\/p>\n

SoC GPU, mis on integreeritud, toetab OpenGL ES 1.1 ja 2.0 ning pakub vahendeid video dekodeerimise kiirendamiseks H.264 ja MPEG-4 formaatides kvaliteediga 1080p30, samuti H.264 formaadis kodeerimist, mis laiendab plaadi kasutusala erinevate multimeedia seadmete ja nutika kodus\u00fcsteemide vahel. Kahjuks on RAM-i suurus piiratud 512 MB-ga ja seda ei saa f\u00fc\u00fcsiliste piirangute t\u00f5ttu suurendada. 1 GB RAM-i pakkumine n\u00f5uaks keerulise kihilise konstruktsiooni rakendamist, mille realiseerimiseks pole arendajad veel valmis.

Raspberry Pi Zero 2 W plaadi projekteerimise peamine probleem oli LPDDR2 SDRAM-i m\u00e4lu paigutamise k\u00fcsimus. Esimese p\u00f5lvkonna plaadil oli m\u00e4lu paigutatud SoC-kiibi kohal asuvasse lisakihti, mis oli teostatud PoP (package-on-package) tehnoloogia abil, kuid Broadcomi uutes kiipides ei olnud seda v\u00f5rreldes Suure SoC-iga v\u00f5imalik rakendada. Tekkinud probleemi lahendamiseks t\u00f6\u00f6tati koos Broadcomiga v\u00e4lja spetsiaalne kiibi versioon, kus m\u00e4lu oli integreeritud SoC-i.

\"Esimene<\/center> <\/p>\n

Teise probleemina t\u00f5usis soojuse hajutamine, kuna kasutusele v\u00f5eti v\u00f5imsam protsessor. Probleem lahendati, lisades emaplaadile pakse vaskkihte, et suunata ja hajutada soojus protsessorist. Selle t\u00f5ttu suurenes emaplaadi kaal oluliselt, kuid lahendus osutus edukaks ja seda oli piisavalt, et v\u00e4ltida \u00fclekuumenemist piiramatute ajaststressitestide puhul, nagu lineaarne algebra LINPACK, keskkonna temperatuuril 20 kraadi. <\/p>\n

Raspberry Pi Zero 2 W konkurentsi seadmest on k\u00f5ige l\u00e4hemal Hiina plaat Orange Pi Zero Plus2, mille m\u00f5\u00f5dud on 46 \u00d7 48 mm ja hind 35 dollarit, 512 MB RAMi ja Allwinner H3 kiibiga. Orange Pi Zero Plus2 plaat on varustatud 8 GB EMMC Flash-m\u00e4luga, omab t\u00e4issuuruses HDMI-porti, TF kaardi pesa, USB OTG porti ning kontakte mikrofoni, infrapunavastuv\u00f5tja (IR) ja kahe t\u00e4iendava USB-pordi \u00fchendamiseks. Plaadil on neljatuumaline Allwinner H5 (Cortex-A53) protsessor, GPU-ga Mali Mali450 v\u00f5i Allwinner H3 (Cortex-A7) koos GPU-ga Mali400MP2. 40-kontaktilise GPIO asemel on l\u00fchem 26-kontaktiline pistik, mis on \u00fchilduv Raspberry Pi B+-ga. Samuti on saadaval v\u00e4hem v\u00f5imas plaat Orange Pi Zero 2, kuid sellel on 1 GB RAMi ja Etherneti port lisaks Wi-Fi-le.
