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 ?

 

thank you
