Driver just stop working and burn some components

[happylulux]

I have bought 10 servo57A on aliexpress last years, 4 of them are now unusable (don't boot), the 5v pin consume more than 5 amps, it appear just randomly (anything work great during several days, and then, something broke on the driver...and it burn also the microcontroller from wich i used the 5v pin to supply the 5v of the driver). Is it a known malfunction of this driver? from what kind of bad manipulation can it come from?
