Tal como nos modelos anteriores, o Raspberry Pi 4 tamb\u00e9m arranca a partir de um cart\u00e3o microSD. Uma novidade \u00e9 o facto de a sua fonte de alimenta\u00e7\u00e3o padr\u00e3o ser USB-C em vez de Micro USB (embora tamb\u00e9m seja poss\u00edvel aliment\u00e1-lo atrav\u00e9s do HAT PoE).

E vale a pena analisar cada um deles um a um.<\/p>\n\n\n\n<p>Primeiro, o chip WiFi do Raspberry Pi 4 \u00e9 um Cypress CYW43455, o mesmo do Pi 3B+. Funciona com WiFi de banda dupla a 2,4 e 5 GHz e suporta v\u00e1rias normas WiFi: IEEE 802.11 b\/g\/n\/ac.<\/p>\n\n\n\n<p>No que diz respeito ao Bluetooth, o Raspberry Pi 4 funciona tanto com Bluetooth 5 como com Bluetooth Low Energy.<\/p>\n\n\n\n<p>E, finalmente, suporta uma verdadeira Gigabit Ethernet - diretamente ligada ao SoC. Por \"verdadeira\", quero dizer que a liga\u00e7\u00e3o n\u00e3o \u00e9 feita atrav\u00e9s de USB, como acontecia nos modelos anteriores. \u00c9 poss\u00edvel separar a largura de banda entre a Ethernet e o USB. E os pacotes Ethernet n\u00e3o precisam de ser transformados em pacotes USB.<\/p>\n\n\n\n<p>Assim, o Pi 4 tem aproximadamente tr\u00eas vezes mais largura de banda Ethernet do que o 3B+, com uma taxa de transfer\u00eancia de 1 gigabit por segundo (1000 megabits por segundo).<\/p>\n\n\n\n<p>Como referi acima, tamb\u00e9m pode utilizar o HAT PoE como fonte de alimenta\u00e7\u00e3o para o Raspberry Pi 4.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Portos<\/h2>\n\n\n\n<p>Para al\u00e9m das portas HDMI e da porta de alimenta\u00e7\u00e3o USB-C, existe tamb\u00e9m uma tomada AV, na qual pode ligar auscultadores ou um altifalante. Estas s\u00e3o as quatro portas pequenas.<\/p>\n\n\n\n<p>Tamb\u00e9m vem com uma porta Display Serial Interface e uma porta Camera Serial Interface, que s\u00e3o ambas portas horizontais longas no topo do Pi para ligar a cabos de fita.<\/p>\n\n\n\n<p>Mas o Pi 4 tem 5 portas grandes que lhe d\u00e3o essa forma distinta - as portas USB e Ethernet.<\/p>\n\n\n\n<p>Os entusiastas do Raspberry Pi notar\u00e3o rapidamente que, para o Raspberry Pi 4, a empresa decidiu trocar as portas USB e Ethernet. Nos modelos anteriores, a porta Ethernet estava \u00e0 esquerda e as portas USB estavam \u00e0 direita.<\/p>\n\n\n\n<p>No entanto, para que tudo coubesse no novo modelo, tiveram de mudar um pouco as coisas de s\u00edtio.<\/p>\n\n\n\n<p><\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/09\/raspi4-close-up2-edited.jpg\" alt=\"As portas USB e Ethernet\" class=\"wp-image-5185\" style=\"width:493px;height:370px\" width=\"493\" height=\"370\" srcset=\"https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/09\/raspi4-close-up2-edited.jpg 865w, https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/09\/raspi4-close-up2-edited-300x225.jpg 300w, https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/09\/raspi4-close-up2-edited-768x576.jpg 768w, https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/09\/raspi4-close-up2-edited-16x12.jpg 16w\" sizes=\"auto, (max-width: 493px) 100vw, 493px\" \/><\/figure>\n<\/div>\n\n\n<p><\/p>\n\n\n\n<p>Nesta fotografia, pode ver as duas portas USB 2.0 a preto \u00e0 esquerda, as duas portas USB. 3.0 em azul no meio e a porta Ethernet \u00e0 direita.<\/p>\n\n\n\n<p>Se estiver curioso quanto \u00e0s diferen\u00e7as, o USB 2.0 tem uma largura de banda de 480 megabits por segundo e os dados apenas fluem numa dire\u00e7\u00e3o de cada vez.
