Oshpark themselves recommended you use that male plug with overlapping holes?
Oshpark’s fab can actually do oval vias, plated slots. Not officially supported (yet) as there is a chance it won’t get done as it requires the fab to notice it.
Actually the gentlemen from OSHPark sent a revision of the original part back to me (I sent him the .brd file and he fixed it [plus he changed the color of the tDocu and bDocu that made it much easier to look at]), the holes were multi-drill hits when I looked at the part…but I found a more viable replacement in a different library repository anyway
His response in email
I’m really not sure how well that would work, actually. The fab automatically removes overlapping drill hits, so there’s no guarantee anyone will see that it’s supposed to be a slot. The way the fab usually looks for plated slots is by looking for the following:
-A slot outline drawn on the board outline layer
-A copper pad underneath
-at least one drill hit
-A minimum slot size of 40 mil.
It’s also worth noting that we don’t officially support plated slots, so following that guideline isn’t guaranteed to succeed. In a lot of cases, it’s better to simply replace the slot with a large via, and call it done. If you want to go through with it though, I’ve draw the slots on the attached brd file, which should help you out with getting things set up.

P.S. His fix is in the “files” repository from the OP
Plus I don’t think it’s a “via” more or less a groove (multiple drills in a line that overlap) [the “plated slot” he and you were referring to] for the USB locking tab to fit thru, then have solder pad on top and bottom to solder to for retention/strength of the USB plug on the board…makes it MUCH more rigid. I do see the problem with overlapping drills like that though.
Can someone double check the pinouts of the USB’s on both end…I might have the male side backwards, the + and ground pins
It’s way past my bedtime…I work deep nights and I’m getting a bit fuzzy
Dangit!
Aaaaand I had it backwards…fixing…jeez
Ok, went over the USB pins 4x times now…they are correct…even drew out a picture of the connectors and the pins…and oriented it to the board…and fixed the DCP pins as well…with the original yes I had to reverse the D+ and D- pins, with the U1 flipped didn’t need the vias
ok…I’m done…files and everything are in the dropbox repository…if you want to doublecheck…please let me know…thanks
Excellent work, WarHawk-AVG! I will be sure to give this one a shot once my other projects are finished up. Stupid tube amp.
Final revision up…triple checked (even printed out the components, laid them out on paper to ensure the pinouts and everything was correct)
Rounded the edges so the board won’t be as sharp or stabby in your pocket or bag or whatever
I had it correct for the USB connections on my first try, I kept second guessing myself and ended up mucking it up, I did have the D+ and D- backwards, with the orientation on the board the way it is now, don’t need the vias thru the board straight shot to the OUT USB connection
Love to see a picture of this when you get one put together. So close to buying the set up to put one together myself.
I am going to order a set, today is payday, and I don’t think $3 will break the bank
Then just have to order 3X components and just put together, then to test em out
Boards are at fab…ordering the components
Sorry if this is obvious to learned souls like Warhawk, but there is nothing to flash right? Just solder paste and heat. I think this would make a nifty little gift or “stocking stuffer” for folks this Christmas season and I intend to make a bunch. Just going to wait to see how Warhawk fares with his tests after building.
What does this device do?
It ensures your device charges at full speed.
A device will not charge at full speed unless it sees the coding it wants on the usb pins. Problem is, there is no standard. Android wants one code, Apple wants apple code and a few others want different codes.
This chip will adapt and always present the code needed for max charging speed. It switches among 6 different coding schemes.
And as a side effect it will prevent juice jacking. A USB charging port stealing your devices’s data and/or injecting malicious code.

Took me 6 tries to get simple board made, not that learned, but what halo said, automatic ranging of charge scheme, also have tested the chips on my dual port DCP enumerator I made, that one unlike this one needs external power source, this one uses power available and provided by USB port it’s plugged into
Forgive my noobness…but how does this connect to an item you want to charge? Is it a board you install internally, or does it have some sort of USB in/out and connect via charging port, between charger and item to be charged?
Yes, USB male in on left (in), USB Female on right (out), looks like this
The USB Condom is a small and unobtrusive dongle that effectively turns any USB cable into a secure 'charge-only' cable to allow safe recharging from untrusted USB ports.
But automatic due to chip, not static based upon resistors
connect via charging port, between charger and item to be charged?
Just plug and play!
Standard usb female port at one end, standard usb male plug at the other end.
But automatic due to chip, not static based upon resistors
AKA it just works. Whatever you plug in. Max charge speed + juice jack protection.
That $10 usb condom does not do full speed charging. It prevents juice jacking but they don’t mention it does slow charging only. No intelligent chip.

Yup yup
:bigsmile:
Thanks for the quick response.
Can this be ordered as a complete item, build kit, or…just a board, and we buy the parts separately from digikey/mouser/ebay? Will a housing/cover be part of the get-up, or is the board just left exposed?
I am amazed at the talent an ingenuity of BLF members. Nicely done, WH!
So far just board, I put BOM on OSHPark page and here for DIYers, but I am sure RMM might pick em up and sell em, I did it creative commons license no commercial, but put BLF on it because it’s “ours”
No cover as of yet. Need to get one for meaurements then try to figure out printable case

Very interesting, i may want a few of these, especially if RMM starts selling them
