Works with Arduino IDE out of the box

Added the board manager URL and it was recognized immediately. Bluetooth LE works great for my sensor project.

Great board, tiny pins

Performance is excellent for the price. Just be careful when soldering headers as the pins are very close together.

Good hardware, steep learning curve

The board itself seems quality, but I struggled finding specific pinout diagrams for this SuperMini version initially.

Fast and reliable

The S3 chip is noticeably faster than the older ESP32 models. PSRAM helps with larger programs.
