Ko nga Ratonga Hanga Hiko kotahi-mutu, ka awhina i a koe ki te whakatutuki i o hua hiko mai i te PCB & PCBA

Rahipere Pi 4B

Whakaahuatanga Poto:

Ko te Raspberry Pi 4B he taapiri hou ki te whanau Raspberry PI o nga rorohiko. Ko te tere o te tukatuka ka tino pai ake ka whakaritea ki te reanga o mua Raspberry Pi 3B+. He taonga rongorau, nui te mahara me te pai ake o te hononga. Mo nga kaiwhakamahi mutunga, ka tukuna e te Raspberry Pi 4B nga mahi papamahi e rite ana ki nga punaha x86PC taumata-urunga.

 

Ko te Raspberry Pi 4B he 64-bit quad-core tukatuka e rere ana i te 1.5Ghz; Whakaaturanga rua me te taumira 4K tae atu ki te 60fps te whakahou; E waatea ana i roto i nga whiringa mahara e toru: 2GB / 4GB / 8GB; I runga i te 2.4/5.0 Ghz Wi-Fi ahokore-rua me te 5.0 BLE iti te kaha Nihokikorangi; 1 gigabit tauranga Ethernet; 2 tauranga USB3.0; 2 USB 2.0 tauranga; 1 5V3A tauranga hiko.

Ko te Raspberry Pi 4 Model B (Raspberry Pi 4 Model B) ko te wha o nga reanga o te whanau Raspberry PI, he rorohiko moroiti, he iti te utu. Ka tae mai me te 1.5GHz 64-bit quad-core ARM Cortex-A72 CPU (Broadcom BCM2711 maramara) e tino whakanui ana i te mana tukatuka me te mahi maha. Ko te Raspberry PI 4B e tautoko ana ki te 8GB o te LPDDR4 RAM, he tauranga USB 3.0 mo te whakawhiti raraunga tere ake, a, mo te wa tuatahi, ka whakauruhia he atanga mana USB Momo-C mo te tere tere me te kaha.

Kei roto ano i te tauira nga atanga Micro HDMI e rua ka taea te whakaputa i te ataata whakatau 4K ki nga kaitirotiro e rua, he pai mo nga teihana mahi pai, mo nga pokapu rongorau ranei. Ko te honohono ahokore whakauru ko te 2.4/5GHz Wi-Fi rua-ropu me te Nihokikorangi 5.0/BLE, e whakarite ana i te whatunga ngawari me te hononga taputapu. I tua atu, ko te Raspberry PI 4B te pupuri i te titi GPIO, e tuku ana i nga kaiwhakamahi ki te hono i nga momo puoro me nga kaitahuri mo te whakawhanaketanga roa, he pai mo te ako i nga kaupapa, kaupapa iot, robotics me nga momo tono DIY auaha.
