STM32Dev rev. b

When designing the Stm32Dev - first version a number of mistakes was made. This lead naturally to the development of Stm32Dev - rev. b.

While the overall design is identical to the first version, a number of tweaks were made. These include:

  • Double headers
  • Different choice of LDO
  • Buttons for NRST and Boot0
  • 8 MHz Crystal
  • Regular blue LED on PC13
  • WS2812B hanging off of PC6

The reasoning behind these choices should be pretty darn obvious, but let me go through them anyway.

Jumper leads on headers

I absolutely positively despise breadboards. True, I might have had bad experiences because my breadboards were cheap crap, but I find myself spending more time chasing down lose connections than I do doing anything productive, so I generally much prefer just to wire stuff up using jumper leads directly on the headers.
