I have the impression that the atmega 328 chip is not original, PORTB.0 replaced with PORTD.1, I have not tested any more functions
Super fast delivery. Nice price... Can be better... bought 10units. 5 units with 328P-MU and 3 units 328P-AU and 2 units with 328P-UTH. Wonder what's the difference? 5 star rating anyway...
