O projeto Raspberry Pi anunciou o lan\u00e7amento da nova placa Raspberry Pi Compute Module 5, que \u00e9 uma vers\u00e3o port\u00e1til do modelo Raspberry Pi 5, medindo apenas 55 \u00d7 40 mm. O pre\u00e7o da placa varia de 45 a 135 d\u00f3lares, dependendo da capacidade de mem\u00f3ria e da presen\u00e7a de suporte para Wi-Fi. <\/p>\n

A placa \u00e9 equipada com o SoC BCM2712, que tamb\u00e9m \u00e9 utilizado no Raspberry Pi 5, e inclui quatro n\u00facleos ARMv8 Cortex-A76 de 64 bits, operando a uma frequ\u00eancia de 2.4GHz, e um acelerador gr\u00e1fico VideoCore VII. Possui duas sa\u00eddas de v\u00eddeo HDMI (4Kp60). O acelerador de v\u00eddeo suporta as APIs gr\u00e1ficas Vulkan 1.3 e OpenGL ES 3.1, e \u00e9 capaz de decodificar v\u00eddeos H.265 (HEVC) com qualidade 4Kp60. A placa possui uma interface PCI Express 2.0, duas interfaces MIPI DSI de quatro canais para tela (DSI) e c\u00e2mera (CSI-2), Ethernet Gigabit, 2 \u00d7 USB 3.0, GPIO de 30 pinos, 6 \u00d7 UART, 5 \u00d7 I2C, 5 \u00d7 UART, 4 \u00d7 PWM, 5 \u00d7 SPI e SDIO 2.0. <\/p>\n

A placa \u00e9 oferecida em vers\u00f5es com diferentes tamanhos de RAM (1GB, 2GB, 4GB, 8GB SDRAM) e eMMC Flash (0GB, 16GB, 32GB, 64GB), bem como com suporte ou sem suporte \u00e0 conectividade sem fio (2.4 GHz, 5.0 GHz IEEE 802.11 b\/g\/n\/ac e Bluetooth 5.0, BLE). Espera-se que, no pr\u00f3ximo ano, uma vers\u00e3o com 16 GB de RAM esteja dispon\u00edvel para venda. A faixa de temperatura de opera\u00e7\u00e3o varia de -20 a 85\u00b0C (a vers\u00e3o anterior da placa poderia operar na faixa de 0\u00b0C a 80\u00b0C).

O conector da placa \u00e9 compat\u00edvel com a vers\u00e3o anterior Raspberry Pi Compute Module 4, permitindo usar a nova placa com a maioria dos acess\u00f3rios lan\u00e7ados para o Compute Module 4. As diferen\u00e7as na pinagem s\u00e3o apenas a remo\u00e7\u00e3o de duas portas USB 3.0 adicionais e dois interfaces MIPI de duas vias. Em termos de desempenho, a nova placa supera a Raspberry Pi Compute Module 4 em 2 a 3 vezes.

Adicionalmente, \u00e9 oferecida uma placa de extens\u00e3o para o Compute Module 5, com portas de entrada\/sa\u00edda extras (Compute Module 5 IO Board), equipada com duas portas HDMI 2.0 de tamanho padr\u00e3o, Gigabit Ethernet com PoE+, duas portas USB 2.0, MicroSD, PCI Express Gen 2, GPIO de 40 pinos, slots para c\u00e2mera e display, uma bateria para o rel\u00f3gio embutido e um conector para ventilador.

Al\u00e9m disso, o projeto Raspberry Pi apresentou a placa Raspberry Pi Pico 2 W, que d\u00e1 continuidade ao desenvolvimento da placa compacta Pico 2, equipada com o microcontrolador RP2350 de sua pr\u00f3pria fabrica\u00e7\u00e3o. A modifica\u00e7\u00e3o marcada com 'W' se destaca pelo suporte a Bluetooth 5.2 e Wi-Fi (2.4GHz 802.11n), implementada com o chip Infineon CYW43439. No restante, a nova placa coincide em caracter\u00edsticas com o modelo Pico 2. O pre\u00e7o da Pico 2 W \u00e9 de $7, que \u00e9 $2 a mais do que a vers\u00e3o sem Wi-Fi. A s\u00e9rie Raspberry Pi Pico \u00e9 voltada principalmente para uso em conjunto com computadores Raspberry Pi, desenvolvimento de sistemas embarcados e controle de diversos dispositivos.

O microcontrolador RP2350 possui um processador de dois n\u00facleos ARM Cortex-M33 com DSP e um bloco para c\u00e1lculos de ponto flutuante, operando a 150MHz, al\u00e9m de dois n\u00facleos opcionais Hazard3 com arquitetura de conjunto de instru\u00e7\u00f5es RISC-V, os quais podem ser alternados durante a inicializa\u00e7\u00e3o para uso no lugar dos n\u00facleos ARM Cortex-M33. O chip conta com 520 KB de mem\u00f3ria RAM embutida, permite a conex\u00e3o de m\u00f3dulos de mem\u00f3ria externa QSPI PSRAM e oferece recursos avan\u00e7ados de seguran\u00e7a. A placa acompanha 4MB de Flash QSPI e \u00e9 totalmente compat\u00edvel com os modelos anteriores Pico 1 em termos de interfaces de hardware e software utilizado para o desenvolvimento de aplica\u00e7\u00f5es. <\/p>\n

O microcontrolador \u00e9 equipado com recursos de prote\u00e7\u00e3o de hardware contra ataques de inje\u00e7\u00e3o de falhas (Fault Injection) e suporta a tecnologia Arm TrustZone, que pode ser utilizada para verifica\u00e7\u00e3o de inicializa\u00e7\u00e3o por assinatura digital, fornece instru\u00e7\u00f5es para acelerar o c\u00e1lculo de hashes SHA-256 e gera\u00e7\u00e3o confi\u00e1vel de n\u00fameros aleat\u00f3rios (TRNG, Gerador de N\u00fameros Aleat\u00f3rios Verdadeiro). Al\u00e9m disso, s\u00e3o fornecidos 8 KB de mem\u00f3ria program\u00e1vel uma \u00fanica vez, permitindo gravar dados que n\u00e3o podem ser alterados ou exclu\u00eddos posteriormente. <\/p>\n

Para criar aplica\u00e7\u00f5es para o Raspberry Pi Pico 2, podem ser utilizados as linguagens C, C++, MicroPython ou CircuitPython. O desenvolvimento em C\/C++ pode ser realizado no editor Visual Studio Code, para o qual h\u00e1 um complemento especial dispon\u00edvel. As capacidades do chip s\u00e3o suficientes para executar aplica\u00e7\u00f5es para resolver problemas de aprendizado de m\u00e1quina, para as quais h\u00e1 um port do framework TensorFlow Lite. Para acesso \u00e0 rede, recomenda-se utilizar a pilha de rede lwIP, que est\u00e1 inclu\u00edda no Pico SDK para o desenvolvimento de aplica\u00e7\u00f5es em C, bem como no firmware com MicroPython.
