View Full Version : Proto USB Help..

I started putting headers on my proto board last night and found it really difficult to see the traces and the micro printing on my board..

I search the site and googled, but was unable to find out any further info on what is where on the board, does anyone have any docs or more info on what is where ( busses lines etc ) for the usb protoboard.. Also my protoboard has an extra cap between vss and the 5 volts lines that I didn't see in any images or docs..

I believe the cap is an a correction that Parallax did in response to some regulators "ringing". It is there for stability, but probably isn't listed on the pictures of it.

What in particular are you having trouble seeing?

I'm just not sure where the lines start and stop.. my eyesight isn't what it use to be.. I just figured there would be a doc on the board explaining more.. but all I can find is the board overview info.
