Arduino IDE compatible
Easy to setup with the STM32duino bootloader. Makes prototyping much faster compared to writing raw register code.

Great for beginners
Works perfectly with ST-Link. I used this for my university embedded systems project and had no issues uploading code.

Good value board
The board itself is high quality, but note that the pin headers are not soldered. You will need to do that yourself.

Pinout confusing
Board works fine but the silkscreen labeling is a bit small. Had to refer to the datasheet frequently to find specific pins.
