Love the S3 chip
Faster than the old ESP32. The matrix is bright and colorful, perfect for status indicators.

Compact powerhouse
The LED matrix makes debugging visual states so much easier. Wi-Fi range is decent for such a small board.

Great for prototypes
Works flawlessly with ESP-IDF. Only downside is no external antenna connector, but onboard is stable.
