Re: [Gumstix-users] A new site from us AUDIOSTIX II feedback

[David V. <dav...@ta...>]

Still would like to see a LCD bias generator on board.
Better yet a MAX3325

RS-232 and LCD bias!

  AUDIOSTIX II feedback

  The extra I/O pins and A/D channels from the UCB1400 should be brought =
to connector or at least to pads/vias so we can solder to them.

  - How about moving the connector labels on the silkscreen so that

  they are still visible after the board is populated ?

  Printing "audio in" and "audio out" somewhere would be even better.

  - It would be nice to have an optional null resistor or jumper

  between USB_VBUS and V_BATT, unless there is a good reason to

  never connect them (?).

  - Similarly, how about an optional jumper between V_BATT and AD0 ?

  (The UCB400 has internal resistive voltage dividers on ADx.)
