I just got a new pro-micro Atmega32U4 board, and installed the current Arduino IDE (1.8) and cannot get it working.
There is no entry for a pro-micro, so iI chose Leonardo as it uses the same chip.
When iI choose upload, the two red ledsLEDs blink fast, but iI get an error from avrdude, saying that it cannot upload the code.
The board is probably from a chinese webshopChinese web shop ($6 clone). There There are no buttons on the board.
My questions are:
Is there already a bootloader on the chip, or do i have to program one? How do i check this?
How does it know that it must receive an upload, instead of running the flash program?
Which board should i choose in the IDE?

This is the error: Couldn't find a Board on the selected port. Check that you have the correct port selected. If it is correct, try pressing the board's reset button after initiating the upload.

itIt looks exactly like this one.
Update: I did everything the manual said. I can choose the pro-micro now. Still the same error message. How do iI check what state the bootloader is in?
