Murphy’s Law

Dealing with STM32F105RB I just had the strangest error. ST-Link started failing on my CANUSB adapter and as I tested on a Rx breakout it failed there to. Moving to F405 it works fine and moving to a 3rd board with F105 it works fine.

Two different boards with the same MCU failing at the same time? I guess I just experiencied Murphy’s Law. Another explenation might be that I finally killed MCU’s with static electricity? If so it would be the first time in the last 6 years! It can also be that I am paying the price for picking up cheap MCU’s from various sources. I seriously which ST could provide a way to sell MCU’s in low volumes for prototyping.
