Find the mistake

F103 Nucleo 64? Cortex-M4?

M4 should be M3 (but I had to look 2 or 3 times)

So, do owners receive a –M patch for downgrading … like the way Intel manages their microcode?

I suspect it would be less expensive to “donate” the boards than to repackage
Maybe university students or Profs who are teaching STM32 classes.

A fake??

Not a fake. This my board :mrgreen: more than 1 year I got it.

That’s not a fake, but an original copy

An original copy, or a copy of the an original?
Now check the MCU just in case it says GD rather than STM…

Frederic, perhaps as you work for STM, they accidentally gave you the new Top Secret prototype of the M4 F103

Perhaps it was right before they decided to rename them F303?

I was’nt in the MCU division at this period

makes perfect sense, increasing the number from 1->3 to indicate you’re going from 3->4

i’d guess 64 pins rhymes with a 4, so the package designer made that M4 instead of M3
