Excellent value
Best price I found for an S3 board with this much PSRAM. Highly recommended for voice assistant builds.

Great hardware specs
16MB flash and 8MB PSRAM is plenty for most voice projects. Wi-Fi range is solid compared to older ESP32 models.

Good board, docs could be better
The board itself is high quality. I wish the English documentation was more detailed for beginners getting started with AI.

Q: Is this compatible with Arduino IDE?
A: Yes, it is fully compatible with Arduino IDE using the ESP32 board manager.
Q: Can I use this for Home Assistant?
A: Yes, many users integrate this board with Home Assistant via ESPHome.
