Perfect for IoT Prototyping
This board works flawlessly with the Arduino IDE. The dual-core processor handles Wi-Fi and sensor data simultaneously without lag. Great value for the price.

Excellent Performance per Dollar
Compared to other dev boards, this offers incredible performance. The built-in hall sensor is a nice bonus for magnetic detection projects. Fast shipping too.

Good starter kit component
Works well with mBlock for block-based programming, which is great for beginners. The only downside is the micro-USB port feels a bit loose, but it still connects fine.

Ideal for Learning Embedded Systems
I bought this for a university project. The documentation is clear, and the Bluetooth connectivity is stable. Highly recommend for students starting with ESP32.

Robust and Reliable
Used this in a home automation setup for three months now. It hasn't disconnected once. The pinout is standard, making it easy to interface with breadboards.

Great board, minor driver issue
The hardware is excellent and compatible with my Makeblock sensors. I had to install the CP2102 driver manually on Windows 10, but once that was done, uploading code was smooth.
Q: Can I power this board using a battery?
A: Yes, you can power the board via the VIN pin or the 5V pin using a Li-Ion battery (3.7V-4.2V) or a 5V battery pack. Ensure the voltage does not exceed 6V to avoid damaging the regulator.
Q: Does this board support 5V logic levels directly on the GPIO pins?
A: No, the ESP32 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 sensors.
Q: What is the maximum current draw for the 3.3V pin?
A: The onboard regulator can supply approximately 600mA total, but it is recommended to keep the load on the 3.3V pin under 500mA to ensure stability, especially when Wi-Fi is active.
Q: Does this come with a case or enclosure?
A: No, this listing is for the development board only. Enclosures are sold separately. However, the board has standard mounting holes compatible with many generic cases.
Q: Is this compatible with the official Arduino IDE?
A: Absolutely. You just need to add the ESP32 board manager URL to your Arduino IDE preferences and install the ESP32 package by Espressif Systems.
