It just might be defective, but when I try to upload sketch,
Arduino and FT232RL module’s LEDs blink back and forth a few times giving me hope, then Arduino goes back to running its already loaded sketch. I get the AVRdude out of sync message.
I’ve tried selecting all the boards and different programmers in the list, downgraded the FTDI driver, and manually configuring the com port settings (also read somewhere about Set RTS On Close).
No luck and I’m out of ideas.
