Exceeded expectations
Fast shipping and the board arrived well-packaged. The antenna placement seems optimized as I get better signal strength compared to my older ESP8266 boards. Very happy with this purchase.

Solid board, minor pin labeling issue
The hardware is robust and WiFi range is impressive. One small critique is that the silk screen for a couple of GPIO pins is slightly hard to read, but the documentation online clears it up quickly.

Reliable performance
Using this for a motor control project. The PWM output is clean and the dual cores allow me to handle WiFi and motor logic separately without lag. Would buy again.

Perfect for IoT Prototyping
This board works flawlessly out of the box. The CH340C driver installed easily on Windows 11, and I was uploading code within minutes. Great value for the dual-core performance.

Best ESP32 board for the price
I've bought five of these for my home automation project. They handle MQTT messages instantly and the Bluetooth connectivity is stable. Highly recommended for beginners and pros alike.
Q: Does the CH340C require specific drivers for macOS?
A: Most modern macOS versions recognize the CH340C automatically. If not, you may need to install the official WCH CH340 driver available on our support page.
Q: Does this board come with headers pre-soldered?
A: No, this version comes without headers soldered to allow for flexible mounting options. You will need to solder your own header pins if required.
Q: Can I power this via the VIN pin instead of USB?
A: Yes, you can power the board via the VIN pin with an external DC supply ranging from 5V to 12V. The onboard regulator will handle the voltage conversion.
Q: Is it compatible with the Arduino IDE?
A: Yes, absolutely. You can install the ESP32 board manager URL in Arduino IDE preferences and select 'ESP32 Dev Module' to start programming immediately.
Q: What is the maximum current this board can supply to sensors?
A: The 3.3V pin can typically supply up to 500mA depending on the USB source, but we recommend keeping high-current loads external to ensure stability for the microcontroller.
