Raspberry Pi 4B

Kufotokozera Kwachidule:

Rasipiberi Pi 4B ndi chowonjezera chatsopano ku banja la Raspberry PI la makompyuta. Kuthamanga kwa purosesa kumakhala bwino kwambiri poyerekeza ndi m'badwo wakale wa Raspberry Pi 3B+. Ili ndi ma multimedia olemera, kukumbukira zambiri komanso kulumikizana kwabwinoko. Kwa ogwiritsa ntchito kumapeto, Raspberry Pi 4B imapereka magwiridwe antchito apakompyuta ofanana ndi machitidwe a x86PC olowera.

Raspberry Pi 4B ili ndi purosesa ya 64-bit quad-core yomwe ikuyenda pa 1.5Ghz; Chiwonetsero chapawiri chokhala ndi malingaliro a 4K mpaka kutsitsimula kwa 60fps; Imapezeka muzosankha zitatu zokumbukira: 2GB/4GB/8GB; M'bwalo 2.4/5.0 Ghz ma WiFi opanda zingwe awiri ndi 5.0 BLE Bluetooth yamphamvu yotsika; 1 gigabit Efaneti doko; 2 USB3.0 madoko; 2 USB 2.0 madoko; 1 5V3A doko lamagetsi.

Rasipiberi Pi 4 Model B (Raspberry Pi 4 Model B) ndi m'badwo wachinayi wa banja la Raspberry PI, makina ogwiritsira ntchito kwambiri, otsika mtengo. Imabwera ndi 1.5GHz 64-bit quad-core ARM Cortex-A72 CPU (Broadcom BCM2711 chip) yomwe imathandizira kwambiri kukonza mphamvu ndi ntchito zambiri. Rasipiberi PI 4B imathandizira mpaka 8GB ya LPDDR4 RAM, ili ndi doko la USB 3.0 losamutsa deta mwachangu ndipo, kwa nthawi yoyamba, imabweretsa mawonekedwe amphamvu a USB Type-C kuti azilipiritsa mwachangu komanso mphamvu.

Mtunduwu ulinso ndi mawonekedwe apawiri a Micro HDMI omwe amatha kutulutsa kanema wa 4K kwa oyang'anira awiri, ndikupangitsa kuti ikhale yabwino malo ogwirira ntchito kapena ma multimedia. Malumikizidwe opanda zingwe ophatikizika amaphatikiza 2.4/5GHz dual-band Wi-Fi ndi Bluetooth 5.0/BLE, kuwonetsetsa kuti maukonde osinthika ndi kulumikizana kwazida. Kuphatikiza apo, Raspberry PI 4B imasunga pini ya GPIO, yomwe imalola ogwiritsa ntchito kulumikiza masensa osiyanasiyana ndi ma actuators kuti apititse patsogolo chitukuko, ndikupangitsa kuti ikhale yabwino yophunzirira mapulogalamu, ma iot mapulojekiti, ma robotiki ndi mitundu yosiyanasiyana yopangira DIY.
