Great features, compact size
Love the dual-core processor speed. It handles my sensor data logging smoothly. Only wish it had a battery charging circuit built-in, but that's expected for this form factor.

Seamless Arduino integration
Uploaded my first sketch within minutes. The board is recognized immediately by the Arduino IDE. No need to fiddle with boot buttons often. Very stable connection.

Best value ESP32 board
I've bought several of these for my classroom. The build quality is consistent, and the pinout is clearly labeled. Students find the Type-C port much easier to plug in correctly.

Perfect for IoT projects
The Type-C connector is a huge upgrade from the old micro-USB boards. It connects instantly to my laptop, and the CP2102 driver worked without any hassle on Windows 11. Great board for the price.

Solid performance, minor heating
Works exactly as described. Wi-Fi range is impressive. I noticed it gets slightly warm when running both Bluetooth and Wi-Fi at full power, but nothing concerning. Highly recommend for beginners.

Easy to start with
As someone new to embedded systems, this board was very forgiving. Plenty of tutorials online work directly with this model. The Type-C cable included was a nice bonus.
Q: Can I power this board using a Li-Ion battery directly?
A: You should not connect a Li-Ion battery directly to the 5V or 3.3V pins. You can connect a battery to the VIN pin if it is within the acceptable voltage range (typically 5V-12V), or use a dedicated battery module with regulation.
Q: Does this board support 5V logic levels on the GPIO pins?
A: No, the ESP32 operates at 3.3V logic levels. Applying 5V directly to the GPIO pins may damage the module. Please use a level shifter if interfacing with 5V sensors.
Q: Does this module have an external antenna connector?
A: This specific model uses the onboard PCB antenna. It does not feature an IPEX or U.FL connector for an external antenna. For most indoor applications, the onboard antenna provides sufficient range.
Q: Is the CP2102 driver pre-installed on macOS?
A: macOS usually includes native support for CP210x devices. However, if your system does not recognize it automatically, you can download the latest drivers from the Silicon Labs website.
Q: What is the maximum current draw from the 3.3V pin?
A: The onboard regulator can typically supply around 500mA to 600mA total for the board and external components. It is recommended to keep the external load on the 3.3V pin under 200mA to ensure stability.
