Great value, minor documentation gaps
Hardware is solid and the Bluetooth range is impressive. Only giving 4 stars because the pinout diagram on the back is a bit small to read. Otherwise, highly recommended for beginners.

Exceeded expectations
Fast shipping and the board arrived well-packaged. Flashing new firmware is instant. The 38 pins give you plenty of options for expanding your projects with displays and sensors.

Best board for learning embedded systems
Used this for my university final year project. The community support for ESP32 is huge, making it easy to find libraries and examples. Works flawlessly with MicroPython.

Perfect for IoT Prototyping
This ESP32 board is exactly what I needed for my smart home project. The dual-core processor handles WiFi and sensor data simultaneously without lag. Setup with Arduino IDE was seamless.

Robust and Reliable
I've burned out cheaper clones before, but this one has been running 24/7 for three months monitoring temperature and humidity. The build quality feels premium.

Good performance, gets warm
Performance is excellent for the price. Note that it does get slightly warm when using WiFi and Bluetooth together at full power, but nothing concerning. Added a small heatsink just in case.
Q: Is this compatible with the Arduino IDE?
A: Absolutely. You can easily install the ESP32 board manager in Arduino IDE and start coding immediately.
Q: Does this board come with a USB cable included?
A: Yes, the package includes a standard Micro-USB cable for programming and power supply.
Q: Can I power this directly from a 9V battery?
A: It is recommended to use a 5V source via the VIN pin or USB. While there is an onboard regulator, feeding 9V directly may cause excessive heat; a 5V regulated supply is safest.
Q: Does it support Over-The-Air (OTA) updates?
A: Yes, the ESP32 fully supports OTA updates, allowing you to upload new firmware wirelessly once connected to WiFi.
Q: What is the maximum current draw per GPIO pin?
A: Each GPIO pin can source or sink up to 40mA. However, the total current for all ports should not exceed specific limits outlined in the datasheet.
