Hello,
i’m very new to this whole thing. Yesterday i received my first SparkFun Pro Micro 5V.
I spent more or less whole day (after work) messing with Arduino IDE upload problems. Main problem was, my Pro Micro was disconnected after few seconds every time i plugged it in USB.
Today i tried uploading “empty” sketch (few times). Setup() and Loop() are empty (BareMinimum), so now it stays connected. But if i try to upload “Blinky, Hello World” sketch from learn.sparkfun.com website, then i it starts disconnecting after few seconds again. Or uploading “Blink” sketch from Arduino IDE.
I attached screenshot of Arduino IDE Tools Menu, where you can see i have selected correct Board/Processor/etc. I’m not sure about programmer. Like i said i’m new.
And here is also output from Arduino IDE after uploading “BareMinimum” sketch. A bit more info might be helpful to figure out what is going on.
I used [ code ], because it displays it a bit better (readable). Last few lines sort of don’t make any sense to me. “avrdude: Device signature” etc. and “Wrong microcontroller …”.
Any help is appreciated.

Wrong microcontroller found. Did you select the right board from the Tools > Board menu?
