[SOLVED] USB Serial communication fails after repeated queries

retrolefty:

Are there any other Arduinos, with the same connections as the UNO that use the FTDI chip? It seemed like early versions of the Arduino UNO used this chip, but that doesn't seem to be the case anymore.

There are still E-bay Asian sellers selling clones of the prior FTDI equipped Arduino Duemilanove board:

I purchased one of these boards from ebay and have had no success. See this post Programming an Arduino Duemilanove (2009) - #3 by system - IDE 1.x - Arduino Forum.

I give up on that. Instead, I found this board (Seeeduino 3.0) which is perfect.

Not only do I get the FTDI chip, I don't have to cut a trace to prevent the auto-reset. I soldered a wire there so that I can recreate that behavior when necessary, but this is a much more elegant solution
