Dual-core performance is impressive
Running complex sensor fusion algorithms while maintaining a stable Wi-Fi connection. The dual-core processor handles multitasking beautifully. The build quality feels robust despite the small size.

Best upgrade from the original ESP32
The S3 chip is a significant upgrade. More GPIOs, better AI instructions, and native USB make development much smoother. This SuperMini version fits perfectly into tight enclosures where the old boards wouldn't fit.

Great board, minor pin labeling issue
Performance is excellent and the Wi-Fi range is better than expected on this tiny board. Only giving 4 stars because the silk screen pin labels are a bit small to read without a magnifier. Otherwise, a solid choice.

Perfect for compact IoT projects
The SuperMini form factor is exactly what I needed for my wearable project. The native USB support makes flashing code incredibly fast and reliable. Highly recommended for anyone needing a small footprint with big power.

Easy to get started with Arduino
As a beginner, I was worried about setup, but this board worked out of the box with the Arduino IDE. The community support for ESP32-S3 is huge, so finding examples was easy. Great value for money.

Good for smart home sensors
Using these for various temperature and motion sensors around the house. Battery life is decent when using deep sleep modes. Wish it had a built-in battery connector header, but that's a minor inconvenience.
Q: Can I power this board directly with a 3.7V LiPo battery?
A: No, this board does not have a built-in battery charging circuit. You must use a regulated 5V source via the USB-C port or apply a stable 3.3V to the 3.3V pin if you have an external regulator.
Q: Does this board support external antennas?
A: This specific SuperMini model comes with an onboard PCB antenna. It does not have a connector for an external antenna, but the onboard signal strength is sufficient for most indoor applications.
Q: Does it support Camera interfaces?
A: Yes, the ESP32-S3 supports DVP camera interfaces. However, due to the SuperMini form factor, pin access might be tight, so check the pinout diagram carefully before connecting a camera module.
Q: Is it compatible with the standard ESP32 libraries in Arduino IDE?
A: Yes, it is fully compatible. You just need to install the latest ESP32 board package by Espressif Systems in the Board Manager and select 'ESP32S3 Dev Module' as your board.
Q: What is the maximum current draw for the 3.3V pin?
A: The onboard LDO regulator can typically supply up to 600mA. However, for stability, we recommend keeping the load under 500mA if you are also powering the Wi-Fi radio heavily.
