I've never heard about this type of microcontroller. Looks interesting. How is it compared with some of the arduinos?

Look up 'Blue Pill' - the STM32 is a very cheap and much higher spec development board which is Arduino IDE compatible.

The STM32-base project is meant for students and hobbyists. The goal of the STM32-base project is to provide a simple and easy to use base project for working with STM32 microcontrollers.
