===RobotDyn STM32 Mini===
It is often called the '''RobotDyn Black Pill''' because of its black solder mask, and must not be confused with other black STM32 boards also called "Black Pill" such as [[Black Pill|the one from WeAct Studio]].

* It has a diode from VBUS and a more capable power regulator.
* The Micro USB port is through-hole soldered and the pull-up resistor has the correct value.
* The board is also narrower.
