USB 2 Port Hub DCP Enumerator / Charge Adapter V2

I haven’t yet…haven’t even produced one yet, this was my initial release for the idea

Still needs TONS of tweaking

I might even hit up a person that can do some 3D printing (for custom enclosure) :wink:

i was wondering what farty used for the 4 port one…
6 ports and a custom enclosure sounds very cool!
i would like to use one of these with the existing power supply in my desktop, finding someway to thread a cable through the back of the case.
i think it makes a lot of sense, and might save around 10% electricity vs a couple of dedicated ac adapters (my power supply is supposed to be rated 85 plus multiplied by above step down converter at 94, vs 70 found in various adapters…).

I shrank the board, it definitely costs much less (only problem is the daggum silk screen on the top for the USB connectors)
They will have an overhang, a printed housing will be able to fit around the overhang better I believe

Detected 2 layer board of 2.09x1.58 inches (53x40mm). $16.50 for three.

Any input? Is there any way I can hide the silk screen of the USB connectors but not the IC’s (or will it matter on the board size?)

Edit the part. Right click a USB connector > Open package. Change > Layer > tDocu, click each line for the usb outline, save. Back on your board, update the usb connectors. Library > Update all. The usb outline will now be on the tDocu layer vs the chip outlines which will still be tPlace.

Nice thanks…the thing is…the CAM processor I use, the Top Silk layer uses both the tPlace and tDocu layers when it makes the gerber…daggumit

Do you think the above render w/ the tPlace makes the board “appear” bigger to OSHpark thus they charge more, the milling layer is the outline of the bottom image 2.09×1.58 inches (53×40mm) so the board physically will be milled out that size, but I think the silkscreen makes the top image bigger than it needs to be…attempting to fix now

AAAAAND nothing…keep getting an error Library SparkFun-Connectors.lbr was not found in current library path(s). Please adjust the library paths or export the drawing libraries first!
Uggh…went to control panel made sure the SparkFun library is in the directory, I can select them an use…uggh

Edit your cam job or Change > Layer > tTest instead of tDocu.
Slikscreen does not seem to effect board cost.

You can also charge over each usb port by using Replace.

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)

USB connector like this

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