   * when PWM output is used, you can mix the two colors (red and blue) quite well due to the persistence of vision (also because the LEDs are next to each other and the small hole in the case is in the center).

 This one has an "M" logo instead of the ST logo, probably corresponding to the "MX-LINK V2" marking on the board.

+This variant uses an STM32F103.
+It seems this micro-controller got so popular that it is now cheaper than the STM32F101 (with less features).
+The annoying details of this variant is that the SWDIO and SWCLK signal described on the pinout engraved in the aluminium case are swapped.
+This shows again the importance of also checking the pinout on the board itself, else you can waste a couple of hours debugging.

+This variant uses an STM32F103 in the UFQFN-48 package.
+This is just a couple of cents cheaper than the more traditional TQFP-48 package, but this is enough en mass to change the footprint on the board.
