Ap\u00f3s tr\u00eas anos e meio desde a sua cria\u00e7\u00e3o<\/a><\/noindex> a Raspberry Pi 3 da organiza\u00e7\u00e3o Raspberry Pi Foundation apresentou<\/a><\/noindex> nova gera\u00e7\u00e3o de placas Raspberry Pi 4<\/a><\/noindex>. O modelo «B» j\u00e1 est\u00e1 dispon\u00edvel para pedido. equipado com<\/a><\/noindex> o novo SoC BCM2711, que representa uma vers\u00e3o completamente reformulada do chip BCM283X anterior, fabricado com tecnologia de 28nm. O pre\u00e7o da placa permaneceu inalterado e continua sendo de 35 d\u00f3lares. <\/p>\n

O SoC ainda inclui quatro n\u00facleos ARMv8 de 64 bits e opera em uma frequ\u00eancia ligeiramente aumentada (1,5 GHz em vez de 1,4 GHz). A mudan\u00e7a de tecnologia permitiu substituir o Cortex-A53 por um n\u00facleo Cortex-A72 de maior desempenho, levando o desempenho a um novo patamar. Al\u00e9m disso, houve uma transi\u00e7\u00e3o para o uso de mem\u00f3ria LPDDR4, que oferece um aumento de largura de banda tr\u00eas vezes maior em compara\u00e7\u00e3o com a mem\u00f3ria LPDDR2 anterior. Como resultado, em testes de desempenho, a nova placa supera o modelo anterior Raspberry Pi 3B+ de 2 a 4 vezes.<\/p>\n

Entre outras diferen\u00e7as significativas, destaca-se a inclus\u00e3o de um controlador PCI Express, duas portas USB 3.0 (mais duas portas USB 2.0) e duas portas Micro HDMI (anteriormente havia uma porta HDMI de tamanho completo), permitindo a sa\u00edda de v\u00eddeo em dois monitores com qualidade 4K. O processador gr\u00e1fico VideoCore VI foi significativamente atualizado, suportando OpenGL ES 3.0 e capaz de decodificar v\u00eddeo H.265 com qualidade 4Kp60 (ou 4Kp30 em dois monitores). A alimenta\u00e7\u00e3o pode ser fornecida atrav\u00e9s da porta USB-C (anteriormente era USB micro-B), atrav\u00e9s do GPIO ou atrav\u00e9s de um m\u00f3dulo<\/a><\/noindex> PoE HAT (Power over Ethernet).<\/p>\n

Al\u00e9m disso, um problema antigo com a quantidade insuficiente de mem\u00f3ria RAM foi resolvido - a placa agora \u00e9 oferecida em vers\u00f5es com 1, 2 e 4 GB de RAM (pre\u00e7os respectivamente $35, $45 e $55), tornando a nova placa uma solu\u00e7\u00e3o adequada para a cria\u00e7\u00e3o de esta\u00e7\u00f5es de trabalho, plataformas de jogos, servidores, gateways para casas inteligentes, controladores de rob\u00f4s e sistemas multim\u00eddia modernos. <\/p>\n

Controlador Ethernet gigabit aprimorado, que agora est\u00e1 conectado ao SoC atrav\u00e9s de um barramento RGMII separado, permitindo atingir o desempenho total anunciado. USB agora \u00e9 implementado atrav\u00e9s de um controlador VLI separado, conectado via PCI Express e fornece uma largura de banda total de 4 Gbps. Como antes, a placa est\u00e1 equipada com 40 portas GPIO, DSI (conex\u00e3o de tela sens\u00edvel ao toque), CSI (conex\u00e3o de c\u00e2mera) e um chip de comunica\u00e7\u00e3o sem fio que suporta o padr\u00e3o 802.11ac, opera\u00e7\u00e3o em frequ\u00eancias de 2,4 GHz e 5 GHz e Bluetooth 5.0.<\/p>\n

\"Placa<\/a><\/noindex><\/center><\/p>\n

Um novo lan\u00e7amento da distribui\u00e7\u00e3o foi publicado simultaneamente Raspbian<\/a><\/noindex>, que oferece suporte completo ao Raspberry Pi 4. O lan\u00e7amento tamb\u00e9m se destaca pela migra\u00e7\u00e3o para a base Debian 10 «Buster» (anteriormente, era utilizado o Debian 9), uma reformula\u00e7\u00e3o significativa da interface do usu\u00e1rio e a utiliza\u00e7\u00e3o de um novo driver Mesa V3D com suporte 3D substancialmente melhorado (incluindo o uso dispon\u00edvel do OpenGL para acelera\u00e7\u00e3o de navegadores). Duas compila\u00e7\u00f5es foram preparadas para download - reduzida (406 MB<\/a><\/noindex>) para sistemas de servidor e uma completa (1,1 GB<\/a><\/noindex>), fornecida com um ambiente de usu\u00e1rio PIXEL<\/a><\/noindex> (um fork do LXDE). Para instala\u00e7\u00e3o a partir de reposit\u00f3rios<\/a><\/noindex> est\u00e3o dispon\u00edveis cerca de 35 mil pacotes. <\/p>\n
