i see some guys just use a inside pcb conver micro usb to ttl inside route,i think that's pretty cool,so i wana design some smaller board to doing that,but if i just make few board,it's kind cost,so i think why i make a preorder so i can make some more pcs to the board.
so here is what i think:
* a small board,just covert micro usb to ttl,and a 3.3v power supply.
* it's very small ,just fit like the chip of ft232
* it's with a smt tiny switch,you can switch off the ttl function,in case you dont wana it.
* with a small led...i think it not need..yeah,maybe dont need it,but i wana use it to show the function is work..when switch off,it off too..
there a lot board use pl2302,it's more chip,but i wana use ft232,it's dont because change the usb port so change the com port.
so my think is the preorder of this board is 4.8us for one pcs,just for the preorde.
and the roadmap is:
2013-5-28 start design the pcb
2013-6-8 stop preorder
2013-6-9 start make pcb,and buy the chip
2013-6-20 start shiper the pcb we make
i dont if it's a good idea,or a bad idea...but i think put it in some route,is cool,like wr703,so we dont need a specal cable any more.
so i put it to the ebay sore,here is it.

for now,this my sketch for what i thought:
i think this the five hardware we design
