RandallR:
The problem that I found is that the "Reset" pin on the board is not one you can use to reset your Aquino and start you download. It is an input to the CP2102 to reset the converter chip.The board I got off eBay had an exposed DTR. You need a Capacitor between this 'pin' and reset (pin 1) on the Atmel chip.
I attached a couple photos of a board like mine. I got it to work without too much difficulty.
Why do you need the cap, doesn't the arduino pro mini for example already have a cap onboard?
