  • Like many here, I had some issues getting the Pro Micro to connect to my Windows 7 Arduino IDE environment. I believed I had installed all of the code bits as far as drivers and the Arduino IDE, but I just could not get it to work. Somewhat in desperation, I wired up the reset button suggested to see if I could force the board into the mode I wanted. Lo and Behold! Forcing the Pro Micro via a reset caused Windows to recognize it differently, than it did when not in download code mode and attach the appropriate drivers. Now it works just as well as the Uno R3 does, with both code downloads and serial monitoring from the Arduino IDE flipping back and forth just as you would like. I have not used the reset button again except for that one time driver install. With regard to the micro USB port weakness issue, I think I have “fixed” the problem by simply connecting a USB cord to it once and leaving it in while I am in development. Forewarned is for armed. I disconnect the PC end when I need to power down or disconnect it. My first project ported very easily from the Uno R3 to the Pro Micro - although I did use a completely different set of pins from one to the next. This demonstrates the value of defining constants for which pin you are using at one place in your code - it makes this sort of transition trivial. The Pro Micro appealed to me for the small form factor, USB connectivity (just in case I need to later easily tweak the software), and on board power regulation. I may play with power regulators next to learn how to do this on my own.

No public wish lists :(
