Pre\u021bul modulului variaz\u0103 \u00eentre 45 \u0219i 135 de dolari, \u00een func\u021bie de capacitatea de memorie \u0219i de suportul Wi-Fi. <\/p>\n

Modulul este echipat cu SoC BCM2712, folosit \u0219i \u00een Raspberry Pi 5, \u0219i include patru nuclee ARMv8 Cortex-A76 pe 64 de bi\u021bi, care func\u021bioneaz\u0103 la o frecven\u021b\u0103 de 2.4GHz, \u0219i un accelerator grafic VideoCore VII. Are dou\u0103 ie\u0219iri video HDMI (4Kp60). Acceleratoarele video suport\u0103 API-uri grafice Vulkan 1.3 \u0219i OpenGL ES 3.1 \u0219i sunt capabile s\u0103 decodeze video H.265 (HEVC) cu calitate 4Kp60. Modulul dispune de un interfa\u021b\u0103 PCI Express 2.0, dou\u0103 interfe\u021be MIPI DSI pentru ecran (DSI) \u0219i camer\u0103 (CSI-2), Ethernet Gigabit, 2 × USB 3.0, un GPIO de 30 de pini, 6 × UART, 5 × I2C, 5 × UART, 4 × PWM, 5 × SPI \u0219i SDIO 2.0. <\/p>\n

Placa este disponibil\u0103 \u00een variante cu diferite dimensiuni de RAM (1GB, 2GB, 4GB, 8GB SDRAM) \u0219i Flash eMMC (0GB, 16GB, 32GB, 64GB), precum \u0219i cu suport sau f\u0103r\u0103 suport pentru comunica\u021biile wireless (2.4 GHz, 5.0 GHz IEEE 802.11 b\/g\/n\/ac \u0219i Bluetooth 5.0, BLE). Anul viitor se a\u0219teapt\u0103 lansarea unei variante cu 16GB de RAM. Intervalul de temperatur\u0103 de func\u021bionare este \u00eentre -20 \u0219i 85\u00b0C (versiunea anterioar\u0103 a pl\u0103cii putea func\u021biona \u00eentre 0\u00b0C \u0219i 80\u00b0C).

Conectorul pl\u0103cii este compatibil cu modelul anterior Raspberry Pi Compute Module 4, permi\u021b\u00e2nd utilizarea noii pl\u0103ci cu majoritatea accesoriilor lansate pentru Compute Module 4. Diferen\u021bele \u00een pinout se reduc doar la eliminarea a dou\u0103 porturi USB 3.0 suplimentare \u0219i a dou\u0103 interfe\u021be MIPI duale. \u00cen ceea ce prive\u0219te performan\u021ba, noua plac\u0103 dep\u0103\u0219e\u0219te Raspberry Pi Compute Module 4 de 2-3 ori.

\u00cen plus, proiectul Raspberry Pi a prezentat modulul Raspberry Pi Pico 2 W, care continu\u0103 dezvoltarea pl\u0103cii miniaturale Pico 2, echipat cu microcontrolerul RP2350, dezvoltat intern. Modificarea etichetat\u0103 cu \u201eW\u201d se deosebe\u0219te prin suportul Bluetooth 5.2 \u0219i Wi-Fi (2.4GHz 802.11n), realizat pe baza chip-ului Infineon CYW43439. \u00cen rest, noul modul are acelea\u0219i caracteristici ca modelul Pico 2. Pre\u021bul Pico 2 W este de 7 dolari, ceea ce este cu 2 dolari mai scump dec\u00e2t varianta f\u0103r\u0103 Wi-Fi. Seria Raspberry Pi Pico este orientat\u0103 \u00een principal pentru utilizarea \u00eempreun\u0103 cu computerele Raspberry Pi, pentru dezvoltarea sistemelor \u00eencorporate \u0219i a sistemelor de control pentru diverse dispozitive.

Placa vine cu 4MB QSPI Flash \u0219i este complet compatibil\u0103 cu modelele anterioare Pico 1 la nivel de interfe\u021be hardware \u0219i software utilizat pentru dezvoltarea aplica\u021biilor. <\/p>\n

Microcontrolerul este echipat cu mecanisme hardware integrate de protec\u021bie \u00eempotriva atacurilor de tip Fault Injection \u0219i suport\u0103 tehnologia Arm TrustZone, care poate fi utilizat\u0103 pentru verificarea \u00eenc\u0103rc\u0103rii prin semn\u0103tur\u0103 digital\u0103, furniz\u00e2nd instruc\u021biuni pentru accelerarea calculului hash-urilor SHA-256 \u0219i generarea sigur\u0103 de numere aleatorii (TRNG, True Random Number Generator). De asemenea, sunt disponibile 8 KB de memorie programabil\u0103 o singur\u0103 dat\u0103, care permit salvarea datelor ce nu pot fi ulterior modificate sau \u0219terse. <\/p>\n

Pentru crearea aplica\u021biilor pentru Raspberry Pi Pico 2 pot fi utilizate limbaje precum C, C++, MicroPython sau CircuitPython. Dezvoltarea \u00een C\/C++ poate fi efectuat\u0103 \u00een editorul Visual Studio Code pentru care exist\u0103 un complement special. Capacit\u0103\u021bile cipului sunt suficiente pentru a desf\u0103\u0219ura aplica\u021bii pentru solu\u021bionarea problemelor de \u00eenv\u0103\u021bare automat\u0103, pentru care este disponibil un port al framework-ului TensorFlow Lite. Pentru accesul la re\u021bea se recomand\u0103 utilizarea stivei de re\u021bea lwIP, care este inclus\u0103 \u00een Pico SDK pentru dezvoltarea aplica\u021biilor \u00een C, precum \u0219i \u00een firmware-ul cu MicroPython.
