Best value for education
Bought ten of these for our university lab. Students find them easy to program using Arduino IDE. The built-in battery charging circuit is a huge plus for portable robot projects.

Solid performance for home automation
Using this to control my custom smart lights. The range is good and it handles multiple connections well. Would give 5 stars if it came with header pins pre-soldered.

Perfect for compact IoT projects
The SuperMini form factor is incredible. It fits perfectly into my wearable prototype without adding bulk. Wi-Fi connection is stable and the native USB makes flashing code a breeze.

Fast and reliable
Compilation and upload speeds are significantly faster than older boards. The 8MB PSRAM allows me to run more complex graphics libraries for my display projects.

Great upgrade from ESP32-C3
The dual-core performance and extra GPIOs make this board superior for complex tasks. I love that it supports AI instruction sets which helps with my sensor data processing.

Excellent board, minor pin labeling issue
Performance is top-notch and Bluetooth LE works flawlessly. The only downside is that the pinout silkscreen is a bit small to read without a magnifier, but the documentation online is clear.
Q: Is this compatible with the Arduino IDE out of the box?
A: Yes, it is fully compatible. You simply need to install the ESP32 board package in the Arduino IDE preferences and select 'ESP32S3 Dev Module' from the board list.
Q: Is the USB port capable of acting as a host for keyboards or mice?
A: Yes, the ESP32-S3 chip supports native USB OTG (On-The-Go), allowing it to function as a host for HID devices like keyboards, mice, and game controllers.
Q: Can I power this board directly from a Li-Po battery?
A: Yes, the board features a built-in lithium battery charging circuit. You can connect a single-cell Li-Po battery to the designated BAT+ and BAT- pads.
Q: What antenna options are available on this specific SuperMini model?
A: This model comes with a high-performance onboard PCB antenna. It also includes an IPEX connector footprint if you need to solder an external antenna for extended range.
Q: Does this board support 5V logic levels directly on the GPIO pins?
A: No, the ESP32-S3 GPIO pins operate at 3.3V logic levels. Applying 5V directly to the GPIO pins may damage the board. Please use a level shifter if interfacing with 5V devices.
