  • What’s the frequency stability on the crystal? +/-0.5% means that your date/time could be off by almost 2 whole days at the end of a year. 10ppm or less would be nice since that would cut the error to single digit minutes in a year.

  • Sorry, when I referred to the Arduino Pro, I meant the Pro Mini.

  • What’s the difference between this and the FTDI Basic Breakout Board? This appears to work with the Arduino Stamp but the FTDI Basic Breakout Board is required for the Arduino Pro boards. Are the Arduino Serial USB Board and the FTDI Basic Breakout Board interchangeable? It would be nice if only one type of USB to Serial adapter board were needed to interface with both the Arduino Stamp and the Arduino Pros.

No public wish lists :(
