Just a man with an idea.
Updated: January 20th, 2019
I've updated this project description (again) to clarify a few more things and correct and earlier error.
- Bids exceeding $250 will be immediately deleted.
- This project is not intended to be mass produced, and I intend on making the files freely available. So I need to keep the costs down or it's just not realistic.
I have a very simple and rather small PCB I need designed (roughly 3.5cm x 2.7cm), essentially a bare bones (2) port USB 2.0 HUB (non-powered) with a microSD card reader connected via one of the hubs ports (direct not via USB), and a MicroUSB Type-B Female connection for the other port. The smaller you can make it the better, even if it has to be double sided. Although I would like to be able to hand solder the components as well as keep it to a single side to help reduce the cost of production. The size of the board should also not exceed 1"x2".
No mounting holes are required, neither is an enclosure, like I said, simple!
The USB hub should ideally be designed around the FE1.1S as I have easy access to this component, unless you know of another chip that can allow the operation of a USB device and the SD card simultaneously. The HS8836 and HS8826 are also options. You can see some [Example] diagrams for those in the files tab above. These are examples only!
You should have prior PCB design experience and an understanding of electronic circuits and be independent and free thinking. I have provided a BOM of primary components below, but don't expect any schematics or a complete BOM. I have attached a block diagram in the files section, yeah...sorry it's the best I can do. You're also welcome to suggest changes to the BOM.
You can use Altium, EagleCad, or KiCad for the boards design.
That's really about all the information I can provide you, what can I say, my needs are simple, the idea is simple.
(This is only an example of parts. Please feel free to make changes.)
