Raspberry Pi-projektet har annonceret, at den nye Raspberry Pi Compute Module 5 er blevet tilg\u00e6ngelig for salg. Dette er en kompakt version af Raspberry Pi 5, som kun m\u00e5ler 55 \u00d7 40 mm. Prisen p\u00e5 modulet ligger mellem 45 og 135 dollars, afh\u00e6ngigt af hukommelsesst\u00f8rrelsen og tilg\u00e6ngeligheden af Wi-Fi. <\/p>\n

Modulet er udstyret med en SoC BCM2712, som ogs\u00e5 anvendes i Raspberry Pi 5, og inkluderer fire 64-bit ARMv8 Cortex-A76 kerner, der k\u00f8rer ved 2,4 GHz, samt en VideoCore VII grafikhurtiger. Der er to HDMI videoudgange (4Kp60). Grafikhurtigeren underst\u00f8tter grafiske API'er som Vulkan 1.3 og OpenGL ES 3.1, og den kan dekode H.265 (HEVC) video i 4Kp60 kvalitet. Modulet har en PCI Express 2.0 interface, to fire-kanals MIPI DSI interfaces til sk\u00e6rmen (DSI) og kameraet (CSI-2), Gigabit Ethernet, 2 \u00d7 USB 3.0, 30-pins GPIO, 6 \u00d7 UART, 5 \u00d7 I2C, 5 \u00d7 UART, 4 \u00d7 PWM, 5 \u00d7 SPI og SDIO 2.0. <\/p>\n

Kortet f\u00e5s i varianter med forskellige RAM-st\u00f8rrelser (1GB, 2GB, 4GB, 8GB SDRAM) og eMMC Flash (0GB, 16GB, 32GB, 64GB), samt med eller uden tr\u00e5dl\u00f8s support (2.4 GHz, 5.0 GHz IEEE 802.11 b\/g\/n\/ac og Bluetooth 5.0, BLE). I n\u00e6ste \u00e5r forventes en variant med 16 GB RAM at blive tilg\u00e6ngelig. Arbejds-temperaturomr\u00e5det er fra -20 til 85\u00b0C (den tidligere version af kortet kunne fungere i omr\u00e5det fra 0\u00b0C til 80\u00b0C).

\"Projektet<\/center> <\/p>\n

Stikket til tilslutning af kortet svarer til den tidligere Raspberry Pi Compute Module 4-model og er kompatibelt med denne, hvilket g\u00f8r det muligt at bruge det nye kort med de fleste tilbeh\u00f8r, der blev udgivet til Compute Module 4. Forskellene i pin-konfigurationen er kun de to ekstra USB 3.0-porte og to to-kanals MIPI-interfaces, der er fjernet. Ydelsesm\u00e6ssigt overg\u00e5r det nye kort Raspberry Pi Compute Module 4 med 2-3 gange.

Derudover tilbydes et kort til udvidelse af Compute Module 5 med ekstra ind-\/udgange (Compute Module 5 IO Board), som er udstyret med to fuld st\u00f8rrelse HDMI 2.0-porte, Gigabit Ethernet med PoE+, to USB 2.0-porte, MicroSD, PCI Express Gen 2, 40-pin GPIO, slots til kamera og sk\u00e6rm, et batteri til interne ure og en forbindelse til en bl\u00e6ser.

Desuden pr\u00e6senterede Raspberry Pi-projektet Raspberry Pi Pico 2 W, som bygger videre p\u00e5 den kompakte Pico 2, der er udstyret med en mikrocontroller, RP2350, udviklet af dem selv. \"W\"-varianten adskiller sig ved at underst\u00f8tte Bluetooth 5.2 og Wi-Fi (2.4GHz 802.11n), implementeret med Infineon CYW43439-chippen. Ellers matcher de nye specifikationer dem fra Pico 2. Prisen for Pico 2 W er $7, som er $2 dyrere end varianten uden Wi-Fi. Raspberry Pi Pico serien er prim\u00e6rt rettet mod brug sammen med Raspberry Pi-computere, udvikling af indlejrede systemer og kontrolsystemer til forskellige enheder.

\"Projektet<\/center> <\/p>\n

Mikrokontrolleren RP2350 inkluderer en dual-core ARM Cortex-M33 processor med DSP og en enhed til flydende punktberegninger, der arbejder ved 150MHz, samt to valgfrie Hazard3-kerners RISC-V-arkitektur, som kan skiftes under opstart for at blive brugt i stedet for ARM Cortex-M33-kernene. Chippens RAM er udstyret med 520 KB indbygget RAM, muligg\u00f8r tilslutning af eksterne QSPI PSRAM-hukommelsesmoduler og giver avancerede sikkerhedsfunktioner. Boardet leveres med 4MB QSPI Flash og er helt kompatibelt med tidligere modeller af Pico 1 p\u00e5 hardware-interface og software-niveauet, der anvendes til applikationsudvikling. <\/p>\n

Mikrokontrolleren har indbyggede hardwarebeskyttelsesmidler mod fejlindspr\u00f8jtning (Fault Injection) og underst\u00f8tter Arm TrustZone-teknologi, som kan bruges til verifikation af opstart via digital signatur, tilbyder instruktioner til at accelerere SHA-256 hash-beregninger og sikker generering af tilf\u00e6ldige tal (TRNG, True Random Number Generator). Derudover tilbydes der 8 KB engangsprogrammerbar hukommelse, der giver mulighed for at gemme data, der derefter ikke kan \u00e6ndres eller slettes. <\/p>\n

For creating applications for the Raspberry Pi Pico 2, languages such as C, C++, MicroPython, or CircuitPython can be used. Development in C\/C++ can be done in the Visual Studio Code editor, for which a specific extension is available. The chip's capabilities are sufficient for executing applications addressing machine learning tasks, for which there is a port of the TensorFlow Lite framework. For network access, it is recommended to use the lwIP network stack, which is included in the Pico SDK for C language application development, as well as in the MicroPython firmware.
