O projeto Raspberry Pi apresentou a nova placa Raspberry Pi Pico 2, dando continuidade ao desenvolvimento das placas compactas Pico e Pico W, que s\u00e3o equipadas com um microcontrolador de fabrica\u00e7\u00e3o pr\u00f3pria. A placa \u00e9 produzida na f\u00e1brica da Sony e est\u00e1 dispon\u00edvel por 5 d\u00f3lares. Assim como os modelos anteriores, o novo modelo \u00e9 principalmente voltado para uso conjunto com computadores Raspberry Pi, desenvolvimento de sistemas embarcados e controle de diversos dispositivos. At\u00e9 o final do ano, est\u00e1 prevista a libera\u00e7\u00e3o de um modelo Pico 2 W com suporte a Bluetooth e Wi-Fi (2.4GHz 802.11n), implementado atrav\u00e9s do chip Infineon CYW43439. <\/p>\n

A placa Pico 2 se destaca pelo uso do novo microcontrolador RP2350, que em rela\u00e7\u00e3o ao microcontrolador RP2040 utilizado em modelos anteriores, inclui um processador ARM Cortex-M33 de dois n\u00facleos e alto desempenho, com DSP e unidade para c\u00e1lculo com ponto flutuante, operando a 150MHz (anteriormente era utilizado o ARM Cortex-M0+ a 133 MHz). Al\u00e9m disso, ela inclui dois n\u00facleos opcionais Hazard3 com arquitetura RISC-V, que podem ser ativados durante a inicializa\u00e7\u00e3o para uso no lugar dos n\u00facleos ARM Cortex-M33. <\/p>\n

O chip possui 520 KB de mem\u00f3ria RAM incorporada (anteriormente eram 264 KB), permite a conex\u00e3o de m\u00f3dulos de mem\u00f3ria externa QSPI PSRAM e oferece recursos avan\u00e7ados para seguran\u00e7a. A placa Pico 2 vem equipada com 4MB de Flash QSPI, que \u00e9 o dobro da capacidade do modelo anterior. Contudo, a placa \u00e9 totalmente compat\u00edvel com os modelos anteriores em termos de interfaces de hardware e software utilizado para o desenvolvimento de aplica\u00e7\u00f5es.

\"M\u00e3e<\/center> <\/p>\n

O chip RP2350 cont\u00e9m recursos de hardware integrados para prote\u00e7\u00e3o 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 usando assinatura digital, proporcionando 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 Verdadeiros). Al\u00e9m disso, oferece 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

Linguagens como C, C++, MicroPython ou CircuitPython podem ser utilizadas para a cria\u00e7\u00e3o de aplica\u00e7\u00f5es. O desenvolvimento em C\/C++ pode ser realizado no editor Visual Studio Code, para o qual est\u00e1 dispon\u00edvel uma extens\u00e3o espec\u00edfica. As capacidades do chip s\u00e3o suficientes para executar aplica\u00e7\u00f5es destinadas \u00e0 resolu\u00e7\u00e3o de problemas de aprendizagem de m\u00e1quina, para as quais h\u00e1 uma vers\u00e3o 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, assim como no firmware com MicroPython.
