content: Hi!I am in a process of getting a prototype done, and for that I some individual "PCB's" with componets mounted.Since I don't know the first thing about where to get this done, and not getting ripped of for that matter, I thought of Dave's blog.What I need is:A board with 4 USB 3.0 and a "high" tactile switch.A board with 2 3.5 mm jack socket, and a 5.25 mm jack socket.A board with a 3-channel 2A "voltage controlled" "Amplifier"Some of these boards may be combined, but I am not entirely sure yet, because I tend to ask this forum for help/design.(There will be some compensation for your help regarding design etc.)I was going to ask Dave, since I thought he could need some extra income, so he could buy something nice for hes kid.But I am not sure he has time for small stuff like this.Thank you all in advance

content: What exactly do you mean by "done"? PCBs printed? Assembled? Designed?

content: Um... first off, you cannot run USB 3 on a single-layer board. Secondly, it doesn't appear you even know precisely what it is you're asking for?Why don't you tell us what you actually need. Also, given the wording in your post, you want someone else to design it for you and manufacture it for you?

content: You'll get it all for free in this forum, if you want to solder it yourselfWhy do you need an extra board with jacks soldered? If you want to connect it to some other electronics, maybe use a jack which you can screw into a nice case for your project:http://www.digikey.de/product-detail/de/SJ5-43502PM/CP5-43502PM-ND/1956558and just solder some wires to it.What should the 4 USB 3.0 board do? Do you plan to implement an USB host with 4 USB 3.0 device connectors? This would be really ambitious.What are the requirements for your voltage controlled amplifier? Is it for audio, or do you want to drive your GHz ham antenna with it?

content: Hi!Thanks for the quick response.You guys are right, I did not explain this very well...The thing is, that it's hard to explain when you are a rookie to this stuff but I will try.I need these PCBs for a PC chassis.What I am looking for is primarily a "all in one" solution, where the PCB is made and assembled.As for the design/layout I was hoping I could find someone who knew a thing or two about the whole deal, and could make a layout for my specifications.That is why I did not come with much detail about the functions of these boards.

content: To FrankBussThe USB 3 Board, is simply a connector board.It's connected to a PC motherboard, which has the controller.It would be nice if the PCB manufacture also made cables for the PCBsThe "amplifier" board, will be used to supply connected equipment such as fans/pumps etch with a voltage, controlled by an input.So if it gets 5 volts on channel-1, the output will be 5 volts. Or whatever is possible after voltage drop.The board will primarily be controlled by the 3-pin fan header on a PC motherboard.I know this function is easily achieved with today's PWM stuff, but not all things uses PWM.

content: The USB board could be a problem, because any wires, PCB layout or additional connectors can reduce the quality of the USB 3 SuperSpeed mode transfer. I assume your mainboard has already USB 3 connectors mounted on the board? Maybe just buy an USB 3 hub, remove the case from the hub and mount it inside. But you would need to connect an USB cable on one of the outside connectors and then maybe drill a hole to connect it to the internal hub.The amplifier board should be possible. Maybe would be a good idea to add overcurrent protection and detection, too, to see if a motor stalls, which could be reported with LEDs or with a simple USB microcontroller. And add some fuses.

content: Ummm... USB 3.0 and one layer? Even for 2.0 official spec says that at least 3 layers are needed for high speed (480 mbps). USB 3.0 goes up to 5 Gbit. That's deep inside hardcore RF range...Other than that 1 layer pcbs you can do yourself in 1 hour or so (toner transfer or uv exposure and etching).
