hello dear forum,
I used to buy STM32 F103 mcus from my countries biggest supplier
this IC below is 5,- USD there
now becouse of competition I need more cheap products and I imported
this below IC for 2,35 USD from China
I soldered this on to my board and I saw that it is working
( I downloaded code and tried some peripherals )
I could not check all the functions yet
my question ;
this big price difference makes me suspicious
is this second picture genuine or clone ?
did you experience this second ICs ?
can I trust this second ICs ?
whats your opinion ?
