I’m often asked what is the external differences between current Maestro production and the earlier series?
Making the switch over between versions less clear cut are several field reports of Maestro units produced in the transition from what I’ve heard references as Maestro-A (the Early Production units) and Maestro-B (the current production units has of 2018).
Easiest external indicator is the location of the On/Off switch.
Maestro-A (Early Production) has the switch on the top, to the far left:
Early Production Maestro-A Top On/Off Switch Location
Maestro-B (Later Production) has the switch on the Left Side of the unit:
Early Production Maestro-B Left Side On/Off Switch Location
Internal differences haven’t been spelled out more than the improved resolution of the Maestro-B screen and assurances that the Dell OEM module of the Maestro-A was replaced by a better new OEM component. (The original Dell module had product nuances that Dell may have considered “features” in their own use as a tablet, but were not the way FlexRadio users (or FlexRadio itself) expected the module to perform when used as an OEM component in a complex product.)
