Reliable and Fast
I have purchased five of these for a home automation project. All of them connected to my network without issues. The build quality feels solid, and the soldering points are well-defined.

Great value, minor pin labeling issue
Excellent board for the price. Bluetooth connectivity is stable. My only complaint is that some of the pin labels on the silkscreen are slightly hard to read under low light, but the documentation online clarifies everything.

Solid performer
Good range on the Wi-Fi antenna. I tested it in a large house, and it maintained connection through two walls. The only reason for 4 stars is that the micro-USB port feels a bit loose, but it still functions correctly.

Perfect for IoT Projects
This board works flawlessly out of the box. The CH340 driver installed easily on Windows, and I was able to upload my first sketch within minutes. The dual-core performance is noticeable when handling Wi-Fi and sensor data simultaneously.

Best in class for the price
Compared to other ESP32 boards I've used, this one offers the best balance of cost and features. The CH340 chip is reliable, and the power regulation is stable even when driving multiple peripherals.
Q: Does it support MicroPython?
A: Absolutely. You can flash MicroPython firmware onto this board using tools like esptool.py. It runs MicroPython very efficiently thanks to the dual-core processor.
Q: What voltage should I apply to the VIN pin?
A: You can apply 5V to the VIN pin or use the Micro-USB port which supplies 5V. The onboard regulator converts this to 3.3V for the ESP32 chip. Do not exceed 6V to avoid damage.
Q: Can I power sensors directly from the 3.3V pin?
A: Yes, the 3.3V pin can output current for small sensors. However, if your sensor requires more than 500mA, we recommend using an external power source to ensure stability.
Q: Are drivers required for the CH340 chip on Mac?
A: On newer versions of macOS, drivers may not be automatically recognized. You might need to download and install the CH340 VCP driver manually from the manufacturer's website.
Q: Is this board compatible with the Arduino IDE?
A: Yes, this ESP32 board is fully compatible with the Arduino IDE. You will need to install the ESP32 board manager package from the preferences menu to get started.
