Now we connect OpenMV board to computer via microUSB cable as follows:
On Terminal, you can check it. For Windows, you can check it on Device Manager. In Mac, you can type this command to check your board.
$ ls /dev/cu*
For Linux, your check it on /dev/tty*
The following is my Terminal output. It shows /dev/cu.usmodem1411.
The board also is recognized as a flashdrive. You can see it on my Mac machine.
If you see it, you're ready to develop OpenMV board.
