Bluetooth LE works flawlessly
I used this for a wearable sensor project. The Bluetooth Low Energy connectivity is robust and the battery management features are easy to implement. Highly recommend for wearables.

Easy to start with Arduino
As a beginner, I was worried about setup, but it worked immediately with the Arduino IDE after installing the ESP32 board manager. The examples ran without modification.

Good for prototyping industrial sensors
We are testing these for remote monitoring nodes. They handle temperature fluctuations well in our lab tests. Would give 5 stars if it came with header pins pre-soldered.

Great performance, minor pin labeling issue
Processing power is excellent for AI edge tasks. The only downside is that the pinout silkscreen is very small due to the size, so keep the datasheet handy. Otherwise, a solid board for the price.

Perfect for compact IoT projects
The SuperMini form factor is incredible. It fits easily into small enclosures where standard boards won't go. Wi-Fi connection is stable and the native USB makes flashing code a breeze without needing external converters.

Best value S3 board available
Compared to other S3 boards on the market, this offers the best price-to-performance ratio. The 8MB PSRAM is sufficient for most camera or audio processing tasks I throw at it.
Q: Are headers included in the package?
A: No, to maintain the compact SuperMini profile and allow for flexible mounting options, this board is shipped without pre-soldered header pins.
Q: Does this board support external antenna connections?
A: This specific SuperMini model uses an onboard PCB antenna. It does not have a connector for an external antenna.
Q: Is the USB-C port data capable or charge only?
A: The USB-C port supports both data transfer and power. You can use it for programming the board and for serial monitoring.
Q: Can I power this board with a 3.7V LiPo battery directly?
A: No, you should not connect a LiPo battery directly to the 5V or 3.3V pins. This board lacks a built-in lithium charging circuit. Please use a separate TP4056 module or a dedicated battery management system.
Q: What is the current consumption in deep sleep mode?
A: In deep sleep mode with RTC peripherals enabled, the current consumption is typically around 10-15 microamps, depending on your specific code configuration.
