Excellent connectivity range
I was surprised by the Wi-Fi range on this little board. It connects reliably to my router from two rooms away through a wall. Flashing new firmware is fast and stable.

Perfect for IoT beginners
This board is incredibly easy to set up. The CH340 driver installed without issues on Windows 10, and I had my first LED blinking in minutes using the Arduino IDE. Great value for the price.

Solid performance, minor pin labeling confusion
The module works flawlessly for my home automation project. The only downside is that the silkscreen pin labels don't match the GPIO numbers exactly, so keep a pinout diagram handy. Otherwise, highly recommended.

Good but runs warm
Does exactly what it says. It does get a bit warm when handling continuous data transmission, but nothing concerning. Just ensure you have some airflow if enclosing it.

Great for university projects
Bought five of these for a semester project. All of them worked out of the box. The community support for ESP8266 is huge, making troubleshooting very easy.

Versatile and cheap
Using this to add Wi-Fi capabilities to an old retro console mod. The Lua scripting support is a nice bonus for quick prototypes. Can't beat the price point.
Q: Does it support MicroPython?
A: Yes, the ESP8266 chip on this board fully supports MicroPython. You will need to flash the MicroPython firmware binary to get started.
Q: How much flash memory is available for user code?
A: This V3 board comes with 4MB of flash memory. After accounting for the filesystem and core system files, you typically have over 1MB available for your sketches.
Q: Is this board compatible with the Arduino IDE?
A: Yes, absolutely. You can program this NodeMCU V3 using the Arduino IDE by installing the ESP8266 board manager package.
Q: What USB cable do I need to connect this to my computer?
A: You will need a standard Micro USB cable. Please note that some cheap cables are charge-only; ensure you use a data-sync cable for programming.
Q: Can I power this directly with 3.3V pins?
A: While there is a 3.3V output pin, it is recommended to power the board via the Micro USB port or the VIN pin (5V) to ensure stable current supply for Wi-Fi operations.
