nOOb's first project. Design check please.

Former Member

In theory it's going to be a HTTP/FTP server with files stored on an 8GB SDHC.

Fresh design. Never prototyped.

Could be more nouse than signal.

Opinions wanted.

    Hi,

     

    I am not familiar with the components you use, I just had a quick look...

     

    1.) Check schematic connections of Q1 to Q6. Both, source and drain are

    connected to power supplies!

     

    2.) Check values of R1 .. R12. Depending on the speed of your SPI buses,

    they may be a bit high.

     

    Good luck,

    Walter
