Perfect for IoT prototypes
This mini D1 board is incredibly compact and works flawlessly with the Arduino IDE. The built-in USB-to-serial converter makes uploading sketches a breeze without needing extra adapters.

Compact and powerful
The ESP-12F module on this board is genuine. I love how small it is compared to the NodeMCU boards while retaining all the necessary pins for my projects.

Reliable Wi-Fi performance
I've deployed six of these in my smart home setup for sensor nodes. The Wi-Fi signal strength is surprisingly good for such a small form factor, and they haven't dropped connection once.

Good for learning embedded systems
Used this for my university final year project. Documentation online is plentiful. Only downside is the GPIO pin labeling on the silkscreen is a bit tiny to read without magnification.

Great value but needs patience
For the price, you can't beat it. It took me a little while to install the correct drivers on Windows 10, but once that was sorted, it connected immediately. Highly recommended for beginners.

Exceeded expectations
Fast shipping and the board arrived well-packaged. Tested the deep sleep mode for a battery-powered project and the current consumption is exactly as specified in the datasheet.
Q: Can I power this directly with a 3.7V LiPo battery?
A: While the ESP8266 runs on 3.3V, this board includes a voltage regulator. You can safely power it via the VIN pin with a range of 5V to 12V. For direct 3.7V LiPo connection, ensure your specific battery voltage stays within the regulator's dropout limits or use the 3.3V pin with caution.
Q: Does it support Over-The-Air (OTA) updates?
A: Absolutely. Since it has built-in Wi-Fi, you can easily implement OTA updates in your code to upload new firmware wirelessly after the initial USB flash.
Q: How much current can the 3.3V pin supply?
A: The onboard regulator can typically supply up to 600mA, but we recommend drawing no more than 200-300mA from the 3.3V pin to ensure stability, especially when Wi-Fi is transmitting.
Q: What driver do I need for Windows?
A: Most modern versions of this board use the CH340 or CP2102 USB-to-UART bridge. If Windows does not automatically recognize it, please download the CH340 driver from our support page.
Q: Is this board compatible with the Arduino IDE?
A: Yes, this board is fully compatible with the Arduino IDE. You simply need to add the ESP8266 board manager URL to your preferences and install the ESP8266 community package.
