Perfect for IoT prototyping
This double-sided breadboard version is a game changer. It saves so much space on my workbench and makes wiring sensors incredibly fast. The WiFi connection is stable and the board boots up quickly.

Exceeded expectations
For the price, you really can't beat this. It handles multiple sensors and data logging to the cloud without overheating. The double-sided design is very clever and sturdy.

Easy to get started
As a beginner, I was worried about setting up the drivers, but it was plug-and-play on Windows 10. Uploaded my first blink sketch in minutes. The form factor is perfect for small projects.

Good for rapid iteration
The ability to plug this directly into a breadboard without extra wires is fantastic for testing new sensor configurations. WiFi range is decent for indoor use. Would buy again.

Solid build quality
I've bought several of these for my classroom. The soldering is clean, and the USB port feels durable. The expansion board design eliminates the need for jumper wires for basic power and ground connections.

Great value, minor pin labeling issue
The board works flawlessly with the Arduino IDE. My only small complaint is that the pin labels on the silkscreen are a bit tiny, but once you memorize them, it's smooth sailing. Highly recommend for students.
Q: Can I power this board with a 9V battery?
A: While the input pin can accept up to 9V, we recommend using a regulated 5V source via the USB port or VIN pin to ensure stability and prevent damage to the onboard regulator.
Q: What is the maximum current draw per GPIO pin?
A: Each GPIO pin can safely source or sink approximately 12mA. The total current drawn from all pins combined should not exceed the limits specified in the ESP8266 datasheet to avoid instability.
Q: Is this compatible with the Blynk app?
A: Absolutely! This board is fully compatible with Blynk. You just need to install the ESP8266 board manager in your IDE and use the Blynk library.
Q: How do I put the board into flash mode manually?
A: To enter flash mode manually, hold down the FLASH button while pressing and releasing the RESET button, then release the FLASH button. However, most IDEs handle this automatically during upload.
Q: Does this board come with a USB cable included?
A: Yes, the package typically includes a short Micro USB cable for programming and power supply.
