If I need a board with good PCBs, which can support LCD, camera(cmos), WiFi/BT(WG7310), 4 USB host and other interface. The best is having a processor board, which is very small, like some country relaseing the new technology, the name seems is AP module, I don't know.
so where can I get this board? or some files for me to read?

 

U lost me there.....er! after good...

 

Beaglebone, Hawkboard, Raspberry pi, or re-purpose a wifi router.

 

OK, thank you for your help.

I think they are all good. But not all fit my request.
It seems you are good at the embedded board. I find a board, SBC8530 based on TI DM3730 processor, can you tell me how about it?

 

Looks fancy and expensive. If I need new microprocessor, than I will buy a cheap OEM netbook, or notebook, for not much more.

I know zero about microprocessor, it take me forever to blink led, for that I will use microcontroller. For wifi, I found a used and inexpensive WRT54GL router. The WRT54GL uses a Brcm5352 SOC. Applied OpenWRT and elbow grease to add a SD card, JTAG, two USB host, and two Serial ports. Progress is slow and cumbersome for lack of linux, and scripting experience.

 

Aaah ! now I know what this is all about...Fancy stuff.

 

oh, yes, It costs USD159, may be a little expressive, but it seems so strong and the designer must have paid a lot energy to design it. Look the picture, I think it is good.

Well, I don't know how it is, the functions are so many.
Don't you think so?
