An electronic device comprising at least one inputoutput circuit in a first supply voltage domain is provided. Particular compounds are of formula I:. The hinge joints include a stop which allows pivoting of adjacent slats only in a direction moving the top surfaces of the slats towards each other, to allow the cover to be rolled up with flexible sheet facing inwardly, and with bottom surfaces of the slats facing outwardly, and not vice versa. The meter further comprises a network interface for interfacing with an external network. The result is a resilient or flexing motion upon actuation of the pinion, thus achieving smooth and zero-backlash adjustment.
