Solid performance, minor documentation gaps
Hardware is excellent and runs cool even under load. I wish the pinout diagram on the back was slightly clearer, but online resources fill the gap easily.

Great for learning embedded systems
I used this for my university project. Uploading code via the Arduino IDE was instant, and the community support for ESP32 is huge.

Good board, steep learning curve for beginners
The hardware is fantastic, but if you are new to MicroPython, expect to spend some time reading tutorials. Once you get it, it's very powerful.

Best bang for your buck
Compared to other dev boards in this category, the 4MB flash and dual wireless capabilities make this a winner. Highly recommended for robotics projects.

Perfect for IoT prototyping
This board works flawlessly with MicroPython. The Wi-Fi connection is stable, and the Bluetooth setup was straightforward. Great value for the price.

Reliable for home automation
Running a sensor node in my living room for three months now without a single disconnect. The dual-core processor handles multiple tasks smoothly.
Q: Is the CP2102 driver included in Windows 10 automatically?
A: In most cases, Windows 10 and 11 will automatically install the CP210x USB to UART Bridge VCP Drivers. If not, they can be easily downloaded from the Silicon Labs website.
Q: Can I power this board with a 3.7V LiPo battery directly?
A: While the ESP32 chip operates at 3.3V, this board is designed to be powered via the 5V Micro-USB input or the VIN pin (3.3V-6V range). For LiPo batteries, we recommend using a dedicated charging module alongside the board rather than connecting directly to the logic pins.
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 draw from the 3.3V pin under 200mA to ensure stability, especially when Wi-Fi is transmitting.
Q: Does this board come with headers pre-soldered?
A: No, this version ships with unsoldered header pins to allow for flexible mounting options. You will need to solder them yourself or use female-to-female jumper wires directly.
Q: Does this support OTA (Over-The-Air) updates?
A: Yes, the ESP32 fully supports OTA updates. You can implement this feature using the Arduino IDE libraries or native MicroPython scripts to update firmware wirelessly.
