Excellent performance
Upgraded from the C3 and the S3 is noticeably faster. Bluetooth LE works great for my sensors.

Great hardware, docs could improve
The board itself is high quality and fast. I wish the pinout diagram was clearer for beginners.

Good but tricky initial setup
Had some driver issues on Windows initially. Once resolved, it works fine for school projects.
