Um pequeno voltímetro digital de baixo custo, serve para colocar em projetos e fontes de alimentação que permita ter as mesmas caraterísticas. Muito pequeno mas bastante luminoso. A embalagem chegou bem sem atrasos. Testei com uma fonte de alimentação de bancada e fiquei surpreendido pela positiva pela precisão deste artigo, Muito bom em relação ao preço, ele arranca na casa dos 2,5 volts mas fica mais bem iluminado com 2,9 a 3 volts. Não é recomendável ultrapassar os 30 volts, vai certamente queimar. Recomendo este artigo.
