Se quiser substituir o seu Raspberry Pi 4 por uma alternativa, seja devido à escassez ou porque quer um desempenho ligeiramente diferente, há uma série de computadores de placa única disponíveis. A Fundação Raspberry Pi está a desenvolver algumas ferramentas maravilhosas com uma enorme comunidade e abriu a porta a muitas placas de desenvolvimento para vários projectos (IoT, servidor, microcontrolador, DIY, etc.). Recomendamos aos utilizadores principiantes que utilizem produtos Raspberry Pi devido à dimensão da comunidade e à ajuda disponível online.
Neste artigo, apresentamos alguns modelos que se aproximam do Raspberry Pi. Existem muitos outros.
N.B.: clique nas imagens para percorrer as informações relativas a cada cartão. No final do artigo, encontra-se disponível um quadro recapitulativo.
