Iyo Raspberry Pi 4 Model B (Raspberry Pi 4 Model B) chizvarwa chechina chemhuri yeRaspberry PI, yakanyanya-performance, yakaderera-inodhura microcomputer. Iyo inouya ne 1.5GHz 64-bit quad-core ARM Cortex-A72 CPU (Broadcom BCM2711 chip) iyo inowedzera zvakanyanya kugadzirisa simba uye kuita zvakawanda. Iyo Raspberry PI 4B inotsigira kusvika ku8GB yeLPDDR4 RAM, ine USB 3.0 chiteshi chekukurumidza kuendesa data uye, kekutanga, inounza USB Type-C simba interface yekuchaja nekukurumidza uye simba.
Iyo modhi zvakare ine mbiri mbiri Micro HDMI interfaces iyo inogona panguva imwe chete kuburitsa 4K resolution vhidhiyo kune maviri mamonitor, ichiita kuti ive yakanaka kune inoshanda nzvimbo dzekushandira kana multimedia nzvimbo. Yakabatanidzwa isina waya yekubatanidza inosanganisira 2.4/5GHz dual-bhendi Wi-Fi uye Bluetooth 5.0/BLE, kuve nechokwadi chinochinjika network uye mudziyo kubatana. Uye zvakare, iyo Raspberry PI 4B inochengeta iyo GPIO pini, ichibvumira vashandisi kuti vabatanidze akasiyana masensa uye actuators kuti awedzere kusimudzira, zvichiita kuti ive yakanakira kudzidza programming, iot mapurojekiti, marobhoti uye akasiyana ekugadzira DIY application.
