Your Kindle will not survive that combination ...

thanks for your responding.
the first thing i want to say : before i posted in this thread i connect my pw2 to my pc serial port (connect rx and tx and gnd only!) !! and i didnt get anything but my pw2 is alive yet

but i have some problems and questions related to your responding:

1.i searched this forum about 7-9 days and i understand somethings and sometimes i got confused. one of them is 1v8 and 3v3 and 5v.
what is this voltage? is it for kindle or is it for power on the chip and adaptor?


2.For some reasons i cann't buy microFTX and ft230xq chip. i thinks i have two way:
make a usb2serial adaptor or buy a FTDI adaptor or buy a PL2303 USB UART BOARD ?
(in this time the easiest adaptor i can find is PL2303 - it works with 3.3 and 5 v)

3.can i buy or make any adaptor and then set its voltage with a 1v8 regulator?
