+How to Identify the which OAK device is connected ?
+###################################################
+Calibrated devices can be identified using the boardName.
+Once the device is connected read the calibration using `calib = device.readCalibration()` followed by `calib.getEepromData().boardName` to get the board name.
+
+Following are the board names assigned to the device during Factory calibration.
