content: HiI want buy a Tablet who have an Option to but on the Bottom additional USB Ports.Sound good? Sure until I saw the USB Port could not connect Water tide.So my Idea is printing a 3D Case with Rubber Seals who have the PCB Inside with the Spring loadet Pins. I found a good sample:When the send me the right Pitch and Pin out I maybe can post that Information.Maybe it get very simple and the USB Port will get routed 1:1 to an USB Port on the PCB or maybe a USB HUB 3.0 Chipset with a refference design.Depend on the Cost an angled PCB would be nice to keep the USB Dongle above the "main" PCB to save space.So what is to price to let someone construct a file who a (Chinese) PCB Manufacture can start to produce it?Thanks!

content: I've worked on a few projects with similar pogo contact & target designs for products that are nominally "one piece" but come apart.can look up the parts I've used, if you like.in one case I had separate pogo and target pads that were soldered on each side.. in another I designed the non-pogo board with hard gold contacts. (enig would probably work for prototype testing but you wouldn't do that in a product)Keep in mind if you want to make these connections carry a USB connection, you of course need to make sure your connection solution maintains USB's requirements for signal integrity and emissions.Also with connections like this you need a separate means of fastening the two halves of the connection in place.. ALSO you need to make sure the connection is guided to be mated correctly, and any incorrect connections that can be made don't wreck the things being connected...also, you can make USB ports water tight if you design them with waterproof covers... samsung did that with micro usb for a few generations of galaxy phones.

content: QuoteSee my PM.The "original" have a seal to the Tablet and covered USB Ports who are Watertide only when closed.I will have some similar but with an additional USB Hardware inside the 3D Printed Hardware.And from that device will going an Antenna Port outside who an Antenna is connected to. So everything will stay water tide.QuoteSURE the Hardware get screwed on the bottom of the Tablet like the original.QuoteThats why I looking for a professional who know about all the thinks.Another idea to get the right Pitch and Layout! I just print a connector (Gray on the Image) and connect the Pins with an connector the PCB.QuoteWell the are on the bottom of the Tablet. So the Pins must push against the Tablet Bottom.QuoteI would say its a simple think because the Ports are used for a Docking station and there is a working product who is ok but not perfect.

content: aaah, ok... well from what I can tell, to summarise the situation1) existing OEM tablet has existing pogo pin interface w/ lock down for expansion modules2) you can buy a USB expansion module for it from the OEM.3) you want someone to redesign a new expansion module with the same attachment design as OEM equipment, but with an added radio attached internally to one of the USB ports? (and maybe no available external ports, bar an external antenna connector?)First question - How many of these are you going to be making?

content: QuoteIts a Tablet who is on the Marked right now. Nothing special.QuoteYes but the USB Connection is not Water tide. So I will make a Copy of that and instead of the "external" Port the are intern only.QuoteI need "just" someone who make a PCB depend whats cheaper with solder Spring loaded Pins on the PCB or on a separate (3D Printed) Connector. Depend how the Ports on the Tablet are design a USB Hub (Chipset) is required on my PCB. Than maybe still depend on the price with a 90degree angled Board the USB Connector are mount so my Hardware will fit above the PCB and save Space.Around that a 3D Print Case should keep everything Water resistant.

content: That sounds like a very hard to quote job. There's an extreme amount of variability in it. Good luck!

content: Not realy. Its more like a USB Hub with the Spring loaded Pins and a 90degree Board with X USB Ports.I hope the dont use any fancy thinks in "there" external USB Pin out.

content: Help!The put much more afford into the product as I was intend!What i expected the used a USB 3.0 Hub:https://media.digikey.com/pdf/data%20sheets/microchip%20pdfs/usb5534b.pdfOn the Top is another big Chip this:https://www.jotrin.com/product/parts/NS692412What is that?On the bottom side is a USB to Network Chipset:https://www.realtek.com/en/products/communications-network-ics/item/rtl8153OMG now I got a littlebit shocked. The use some I2C interface Chipset:https://www.mouser.at/ProductDetail/Microchip-Technology/MCP23017-E-ML?qs=usxtMOJb1RwOdfCNDE63wQ%3D%3DDoes the do some fancy check if the Module is legitimated?Thanks

content: yep...... weird specialised ICs is exactly the kind of issue that I was expecting you would run into with cloning an accessory like this. And yes, it's also pretty likely there's some kind of genuine accessory check that you'd have to figure out. (and possible DMCA violation issues to do that)This is why it's really hard to clone stuff like this, it's hardly ever just a "USB hub with spring loaded pins" like you were insisting before.Also, you never said what quantity you needed, which would have been basic information if you wanted to seriously consider a custom PCB and case design.It looks like your only likely option is buy OEM units and modify them to suit your purposes.
