SOQUETE MULTIMEDIA CARD PARA PLACA ARM

[tcpipchip]

Ola, onde posso encontrar este soquete no BRASIL.
Já haviamos comprado uma vez...mas esquecemos onde

TCPIPCHIP

[chipselect]

farnell tinha...

http://www.matrixconnector.com/Products%20Index.htm

O codigo deles para esse soquete é M-135.

A pagina acima é em inglês mas eles estao no brasil.
Pena que no site nao mostra nem a metade da linha de produtos deles.

procura por SD na farnell...o conector é o mesmo do mmc. porem o que pode mudar é a posição dos pinos

Eu tava olhando tua placa e uma coisa me despertou a curiosidade:
no footprint do chip U1 tem um traço no silkscreen que passa por cima de todos os pads. Qual o motivo de você ter feito isso? É para que no momento da solda, ela não escorra para trás, podendo causar um curto com ilhas próximas? Se sim, o resultado foi interessante?
Eu pergunto porque tive problemas desse tipo numa placa aqui, e a solução foi mexer no desenho para jogar as ilhas mais longe dos pads, mas esse esquema me pareceu interessante.

[tcpipchip]

Sim
Nos vimos aplicando esta tecnica a um bom tempo...se nao me engano tiramos a ideia do livro da Sra JAN AXELSON.
Sim, resolveu
As poucos estamos fazendo ela funcar

Nao é fácil o ARM9, eta processador bão e difícil de entender...quero ver o ARM11
Já deu boot parcial do LINUX, falta NFS
