The following is not an attempt for the actual logo, simply demonstrating the idea.

If going for a real cute bug (nothing like the above) i think it would still be cool if its front feet were circular, middle one's triangular, and rear feet square, as a reference to USB.

That would get my vote. I think it's great.

 

Initially, I thought the USB Trident would surely be trademarked or copyrighted, but I can't find it listed in the USB IF documentation linked below.

I think it may help "some" usb dacs. I can't say how much it'll improve the output on, lets say, mobile phones if this was anyway possible but it's food for thought.

 

May not help people like me since I'm a desktop sort of guy.

Hi All,

 

Board received....and it really is purple!  Now waiting on Mouser and Digi-Key.

We found our first error...

The EAGLE footprint for J1 was not correct.

The footprint was set up for pins and the part

has tabs. I have modified the EAGLE footprint

to reflect reality.

 

My recommendation is to trim down the tab

to fit the hole.

Your welcome!

 

Just placed my order too (all from Digi-key).

I don't expect the board for a few more days.

looking at the datasheet, the SMT type version for J1 is a little wide for the board pads, but may work:  http://www.mouser.com/ProductDetail/Hirose-Electric/UX60-MB-5ST/?qs=%2fha2pyFadug63YtrwsEixoQPqVODSOA1lIiVOr57FQKNZt%2fo%252bCTYTA%3d%3d

I fixed the problem for the next run of boards already.

 

I was going to use the smd version but was concerned about mounting security.

I figured the mounting tabs would be more secure.

The full through hole version I did not like, it did not route well.

probably a good idea for those that want to use manly heavy/stiff audiophile USB cables :regular_smile :.

Quick question: what's C8? I don't see it on the BOM...

post #59 of 197

Same question with R5?

post #60 of 197

my MF V-Link USB-S/PDIF converter draws a max 160mA.  I'm wondering if the 200mA DC current rating of the ferrites is enough engineering margin of error?
