When the arduino has an onboard cap in series from DTR pin to the chip's reset, then a cap is not needed on the CP2102 module.
Did you swap them because of the pinout on your arduino, or because the board was mislabeled (that rx was labelled as tx?)?
what/where are these boards you are getting?? (that has the DTR pin broke out)
you dont have to use the 6-pin header do you?
I mean treat this like any other FTDI cable..yes?
as long as I run 5v+, GND, RX, TX to my chip.. Im good.. I can then use/tap the DTR pad from the bottom of the board to use on the DTR of the circuit Im uploading my sketch to....right?
also is there a driver for it?
@msev,a board like you describe is easy to make.
