Good value but needs programmer
The board itself is solid. Just remember this is a core board, so you need an external programmer like ST-Link V2 to upload code.

Works with Arduino IDE
Managed to get it working with the Arduino IDE after installing the STM32 package. Pin mapping took some time to figure out.

Reliable and compact
Using this in a custom drone controller. The 72MHz clock speed is sufficient for my control loops. No issues so far.

Excellent core board for prototyping
This board works flawlessly with the ST-Link programmer. All pins are accessible and labeled clearly. Great for learning ARM development.

Perfect for university projects
Bought this for my embedded systems class. It compiles quickly and handles peripherals well. Highly recommend for beginners.
Q: Is the bootloader pre-installed?
A: Yes, it comes with a generic bootloader that supports serial uploading if configured correctly.
Q: What is the maximum current per IO pin?
A: Each IO pin can source or sink up to 25mA. Please refer to the datasheet for total current limits.
Q: Can I use 5V sensors with this board?
A: Most GPIO pins are 5V tolerant, but the logic level is 3.3V. Level shifters are recommended for sensitive components.
Q: Which debugging interface is supported?
A: This board supports SWD (Serial Wire Debug) and JTAG interfaces for debugging purposes.
Q: Does this board come with a USB connector?
A: No, this is a core board designed for header connections. You will need an external programmer like ST-Link for uploading code.
