Raspberry Pi 4B: Kumbuyuuter yar oo awood leh oo la soo bandhigay

Raspberry Pi 4B: Kombiyuutar yar oo awood badan

Sharaxaad Gaaban:

sharaxaada alaabta
Waa Motherboard-ka microcomputer-ka ah oo ku saleysan ARM, isagoo u isticmaalaya SD/MicroSD kaarka xusuusta Hard Disk-ga. Waxaa jira 1/2/4 USB interfaces iyo 10/100 Ethernet interface oo ku wareegsan Motherboard-ka (nooca A ma laha deked shabakadeed), kaas oo lagu xiri karo Keyboard, mouse iyo cable network, iyo sidoo kale interface wax soo saarka TV calaamadaha analoogga ee fiidiyoowga ah iyo HDMI-ga-muuqaalka wax-soo-saarka fiidiyoowga-sare. Qaybaha sare ku xusan dhamaantood waxa ay ku dhex milmeen Motherboard-ka oo wax yar uun ka weyn kaarka deynta. Waxay leedahay dhammaan hawlaha aasaasiga ah ee PC waxayna u baahan tahay oo kaliya in lagu xiro TV-ga. iyo kiiboodhka, waxa aad qaban kartaa hawlo badan sida xaashida faafinta, habaynta kalmadaha, ciyaarta ciyaarta, ciyaarida muuqaalada qeexida sare, iyo in ka badan. Moodeelka Raspberry Pi B waxa uu bixiyaa kaliya looxa kombuyuutarka, ma laha awood xusuusta, kiiboodhka, chassis ama xidhiidhada.

Astaamaha muhiimka ah ee Raspberry Pi 4B:
Xawaaraha farsamaynta degdega ah:
1. Broadcom 2711-kii ugu dambeeyay ee Quad-core Cortex A72 (ARM V8-A) 64-bit SoC Processor oo ku xiran 1.5GHz waxay wanaajisaa isticmaalka awoodda; iyo kulaylka ku yaal Pi 4+B waxay la macno tahay in CPU-da BCM2837 SoC ay hadda ku socon karto 1.5 GHz Taasi waa 20% horumarin marka loo eego qaabkii hore ee Pi 3, kaasoo ku socday 1.2GHz.
2. Waxqabadka fiidiyooga ee Pi 4 B ayaa lagu cusboonaysiiyay taageerada laba-geesoodka ah ee xallinta ilaa 4K iyada oo loo marayo labo dekedood; fiidiyooga qalabaynta ee 4Kp60, taageerada H 265 dejinta (4kp 60); H.264 iyo MPEG-4 codaynta (1080p60).

Wireless-ka degdega ah:
1. Marka la barbardhigo qaabkii hore ee Pi 3, isbeddelka weyn ee Pi 4 B waa ku darida mid cusub, dhakhso badan; Chip wireless laba-band ah oo taageera 802.11 b/g/n/ac wireless LAN.
2. Dual-band 2.4GHz iyo 5GHz wireless LAN waxay taageertaa isku xirka shabakadaha degdega ah oo leh faragelin yar, iyo tignoolajiyada anteenada PCB ee cusub waxay taageertaa soo dhawayn wanaagsan.
3. 5.0-kii ugu dambeeyay wuxuu kuu ogolaanayaa inaad isticmaasho kumbuyuutarka wireless-ka / raadraaca raadraaca oo ka badan intii hore, iyada oo aan lahayn dongles dheeraad ah; waxa ay ilaalisaa nadaafada.

Isku xirka Ethernet ee la xoojiyey:
1. Pi 4 B waxa uu leeyahay isku xidhka fiilooyinka degdega ah, oo leh tignoolajiyada USB 3.0; Thanks to chip-ka USB/LAN ee la cusboonaysiiyay; waa inaad aragto xawaare ilaa 10 jeer ka dheereeya moodooyinkii hore ee Pi.
2. Madaxa GPIO waa sidiisii, 40 biin; si buuxda gadaal ugu socota oo la jaan qaadaya Motherboard-yadii hore, sida saddexda nooc ee ugu horreeya ee Pi. Si kastaba ha ahaatee; waa in la ogaadaa in furayaasha cusub ee PoE ay la soo xiriiri karaan qaybaha dhinaca hoose ee koofiyadaha qaarkood; sida koofiyadaha qaanso-roobaadka.
