It offers a complete and self-contained networking solution, allowing it to either host the application or to offload from another application processor. Instruction & Steps of How to use: 1. Download the Arduino IDE, the latest version. 2. Install the IDE 3. Set up your Arduino IDE as: Go to File->Preferences and copy the URL below to get the ESP board manager extensions: arduino.esp8266.com/stable/package_esp8266com_index.json 4. Go to Tools > Board > Board Manager> Type "esp8266" and download the Community esp8266 and install. 5. Set up your chip as: Tools -> Board -> NodeMCU 1.0 (ESP-12E Module) Tools -> Flash Size -> 4M (3M SPIFFS) Tools -> CPU Frequency -> 80 Mhz Tools -> Upload Speed -> 921600 Tools-->Port--> (whatever it is) 6. Download and run the 32 bit flasher exe at Github(Search for nodemcu/nodemcu-flasher/tree/master/ at Github) github.com/nodemcu/nodemcu-flasher/tree/master/Win32/Release Or download and run the 64 bit flasher exe at: github.com/nodemcu/nodemcu-flasher/tree/master/Win64/Release 7. In Arduino IDE, look for the old fashioned Blink program. Load, compile and upload. 8. Go to FILE> EXAMPLES> ESP8266> BLINK, it will start blinking.

The huzzah esp8266 breakout requires a ftdi cable for programming. The huzzah feather is closer to this unit but costs about 20 dollars. **Q: Does this dev board have an integrated power regulator** A: Yes, it has a integrated power regulator. You can supply 5V (via USB or board pin) and the system runs on 3.3V. You can even pull 3.3V off the pin(s) to your external components, or supply 3.3V on the appropriate pin. **Q: Is it meant to be powered by the USB port?** A: While you can power it from any USB port, the point is after you load your code to the board it's wi-fi and can operate independently with a 5vdc power source. The ESP32 CAM modules are really cool. You can set up a 5 camera home security system for about $50. **Q: do I just plug this into my Arduino Uno? will it work with other stacked shields?** A: Short answer: no. But you can get a simpler (and cheaper, incidentally) esp8266 module (not the dev board) and use it to connect your Arduino to wifi. I suppose you probably could rig this up to work, actually, but it would kind of be overkill, and would NOT work with shields. A small basic esp8266 might be able to be worked into a proto shield for what you seem to be looking for. There are several tutorials on using the esp8266-01 (this is the -12e) to connect Arduino to wifi. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by M***C on April 4, 2026* ### ⭐⭐⭐⭐⭐ Review *by J***S on November 26, 2023* ### ⭐⭐⭐⭐⭐ Review *by M***D on April 26, 2025* ## Frequently Bought Together - HiLetgo 3pcs ESP8266 NodeMCU CP2102 ESP-12E Development Board Open Source Serial Module Works Great for Arduino IDE/Micropython (Large) - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - BOJACK 3 Values 130 Pcs Solderless Breadboard 4 Pcs 830 Tie Points & 400 Tie Points & 126 Pcs Flexible Breadboard Jumper Wires --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/170107353-3pcs-esp8266-nodemcu-cp2102-esp-12e-development-board-open-source](https://www.desertcart.pt/products/170107353-3pcs-esp8266-nodemcu-cp2102-esp-12e-development-board-open-source) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-05-10*
