Raspberry Pi 4B

Lus piav qhia luv luv:

Raspberry Pi 4B yog ib qho tshiab ntxiv rau Raspberry PI tsev neeg ntawm cov khoos phis tawj. Lub processor ceev tau zoo dua qub piv rau yav dhau los tiam Raspberry Pi 3B +. Nws muaj kev nplua nuj multimedia, ntau lub cim xeeb thiab kev sib txuas zoo dua. Rau cov neeg siv kawg, Raspberry Pi 4B muab cov duab ua haujlwm zoo piv rau qib x86PC nkag.

Raspberry Pi 4B muaj 64-ntsis quad-core processor khiav ntawm 1.5Ghz; Dual zaub nrog 4K daws teeb meem txog 60fps refresh; Muaj nyob rau hauv peb lub cim xeeb xaiv: 2GB / 4GB / 8GB; Onboard 2.4 / 5.0 Ghz dual-band wireless WiFi thiab 5.0 BLE qis zog Bluetooth; 1 gigabit Ethernet chaw nres nkoj; 2 USB 3.0 chaw nres nkoj; 2 USB 2.0 chaw nres nkoj; 15V3A fais fab chaw nres nkoj.

Raspberry Pi 4 Model B (Raspberry Pi 4 Model B) yog lub cim thib plaub ntawm Raspberry PI tsev neeg, lub tshuab ua haujlwm siab, nqi qis. Nws los nrog 1.5GHz 64-ntsis quad-core ARM Cortex-A72 CPU (Broadcom BCM2711 nti) uas ua rau muaj zog ua haujlwm ntau thiab ua haujlwm ntau. Lub Raspberry PI 4B txhawb nqa txog li 8GB ntawm LPDDR4 RAM, muaj USB 3.0 chaw nres nkoj rau kev hloov cov ntaub ntawv sai dua thiab, thawj zaug, qhia txog USB Hom-C lub zog sib txuas rau kev them nyiaj sai thiab lub zog.

Tus qauv kuj tseem muaj ob lub Micro HDMI interfaces uas tuaj yeem ua ib txhij tso tawm 4K daws teeb meem video rau ob lub saib, ua rau nws zoo tagnrho rau cov chaw ua haujlwm tau zoo lossis chaw ntau ntau. Integrated wireless connectivity suav nrog 2.4 / 5GHz dual-band Wi-Fi thiab Bluetooth 5.0 / BLE, kom ntseeg tau tias kev sib txuas tau yooj yim thiab cov khoom siv sib txuas. Tsis tas li ntawd, Raspberry PI 4B khaws cov GPIO tus pin, tso cai rau cov neeg siv txuas ntau yam sensors thiab actuators rau kev txhim kho txuas ntxiv, ua rau nws zoo tagnrho rau kev kawm programming, iot tej yaam num, robotics thiab ntau yam muaj tswv yim DIY daim ntaub ntawv.
