Question about Cubeblack firmware


What do the following numbers in the picture bellow mean?
more specifically: what does the number of “CubeBlack” (under the “messages” screen) mean? while the ArduCopter and ChibiOS versions are constant in every pixhawk (ver 4.0.1), the “CubeBlack” varies.


It’s a serial number, the Cubes do have valid unique serial numbers whereas most other boards dont and they will all display the same.
