  • "a few hours of troubleshooting"? This sucker (me) spent a week in despair and frustration! Even bought a second Pro board to rule out broken hardware. I guess the idea with the resistors is to ensure priority for the USB serial connection (with an FTDI) over the D0/D1 UART. As you say, it is not on th Pro Mini, but some other boards have it the other way around, ie resistors "blocking" the USB serial if there is a conflict in use.

  • Oh yes, there is! Check these cuties out: http://www.sparkfun.com/products/9709

  • I have browsed the earlier posts but couldn't see that this ambiguity in the description of the "green wire pin" has been mentioned :

    In the schematic the JP9 pinout reads thus: GND // GND // VCC // RX-I // TX-O // DTR

    While in the photos it is clearly: GND // GND // 3.3V // RX-I // TX-O // RTS

    Has there been a change sometime earlier or is the scematic simply wrong?

  • I would also very much like to know if the Wire library works! I have just ordered this board (3v3 8MHz) and was planning to use it with an application of mine which relies on the Wire library for I2C communication.

No public wish lists :(
