USB 2 Port Hub DCP Enumerator / Charge Adapter V2

Good start, but why not switch it up a bit. It should be easy to cut the board down to 1/3 it’s current size and set it up for stacking. You’ve got the ports segregated into two’s anyway. As a matter of fact, I see no interdependence between the pairs anyway! So just make it a 2-port board and be done…. Since you’re mounting them in boxes anyway I see absolutely no reason to make a 6-port board.

Also you don’t have mounting holes yet.

If you want to maintain your current port layout (2/2/2/0) you can just make the 2-port version trapezoidal. No reason they can’t fit into the same space. You’ll save money overall (cost per 6 ports will go down) because lots of space is unused in the 6-up version.

Found the replacement part, changing, a tiny bit different than the USB-A-S but for the most part identical, hopefully “no silk” on render

USB-A-S-NOSILK-FEMALE

nope no change…still renders it…but at $17~ for 3x boards might order a set on payday to see what they come in like

Then to try to get the components past the wife (budget is really tight right now)

I still don’t understand the advantage of putting 3 of these chips on one PCB . The space in the middle of the PCB is wasted… why not just make a PCB with 1 chip and 2 ports and put three of those PCBs in the same project box?

Ok, 2 port, MUCH smaller and cheaper

Anyone interested and want me to share?

I wouldn’t mind playing with your BRD file for a few minutes :wink:

Trapezoid, you want a trapezoid…fine i give you a steenkin’ trapezoid :smiley:

No change in price

On Oshpark all pricing is based on a bounding rectangle which your design fits inside.

Also, what female USB connector part is this designed for? eg do you have a link?

working on the 2 up stacked USB…if I can locate the .lbr

And just like that I find a BETTER IC…the TPS2511!

Well…this one above is more or less being fed a well regulated 5vdc for charging…the TPS2511 IS the regulator…daggumit!

Gimme a few…working on somethin’ somethin’

Here is what I found…a thru hole stacked USB 10 Watt regulated board

Is it adding anything you need? Seems like you’ve already got well regulated 5v, so no need to add cost…

Truthfully it’s not, the chips are about 1/2 the cost of the TPS2513 though, and it does offer some sort of regulation

For a quick snapshot of what it looks like (would like to make it a SMD variant)

I would like to import that part (stacked USB ports)…care to edumicate me on how to do that

I haven’t seen the part, I’m tired of RAR files and don’t have anything that opens them installed. So I’m not sure what needs to be done. It should be as simple as adding the library to your Eagle and then adding the part…

A single port chip that’s 1/2 the cost of a dual port chip… waste of board space?

I still think your 2-port board can be smashed down to around $3.50 with no loss of functionality and similar mounting provisions.

well…here ya go if you want to tinker with it…remember I am an amature at this (not like it doesn’t show…haha)

What are you looking to do? Itseems you already have the part.

I use it where ever I have twelve volts, with my solar set up for instance to charge Ipad and wife’s and my own Iphone.

Have you guys tried Dirty PCBs ? You have to wait for shipping from China but $14 for ten 5cm x 5cm boards is dirt cheap. I tried to upload an OSHPark design to their site but they must need a different format. Complains about a lack of a drill file.

Gerber file extensions are listed on Dirty PCB's about page. They provide a cam job and .dru design rules.

It was on the brd I downloaded but not in my .lbr directory, I wanted to copy from that stacked one that ones mine, so I could replace the single one on my board with a double stacked one…this way the board could like wight said it could be less than 1/2 the size it is now

Wait time from OSHPark is bad enough, and they are made here CONUS…I just like the purple board goodness :slight_smile:

However it might help to get the SRK boards made in 2mm vs 1.6mm (the OSHPark boards are thinner than stock boards and sometimes lead to issues with continuity between the driver and battery tube [aw crap…they charge and extra $20 for the 2.0mm upgrade…fooey])

I wonder if those triple and 7*XML Scaru boards would do better on .6mm thick boards heat wise…hmmm

I wonder how many BLF15.17DD would fit on a 5x5cm panelized board…hmmm
