Review: perfect for WLED and LED projects - Used these for a WLED LED strip project in my room and they worked flawlessly right out of the box. Getting them on WiFi was super easy and the Arduino IDE setup was not bad at all even for someone who is not super deep into embedded stuff. You really cannot beat getting 3 boards for this price, it is a total no brainer for any DIY electronics project. ## Features - Built-in Micro-USB, with flash and reset switches, easy to program - Arduino compatible, works great with the latest Arduino IDE/Mongoose IoT/Micropython - Data download access to the website: http://www;nodemcu;com ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B081CSJV2V | | Best Sellers Rank | #960 in Single Board Computers (Computers & Accessories) | | Brand | HiLetgo | | Built-In Media | 3pcs HiLetgo ESP8266 NodeMCU CP2102 Development Module | | CPU Model | MediaTek MT8125 | | CPU Speed | 80 MHz | | Compatible Devices | ESP8266 | | Connectivity Technology | Wi-Fi | | Customer Reviews | 4.6 out of 5 stars 1,398 Reviews | | Manufacturer | HiLetgo | | Memory Storage Capacity | 0.5 MB | | Model Name | NodeMCU LUA ESP8266 CP2102 ESP-12E | | Number of Items | 3 | | Operating System | Minimalistic operating system or RTOS for microcontrollers | | Processor Brand | Espressif | | Processor Count | 1 | | Processor Speed | 80 MHz | | RAM Memory Technology | LPDDR3 | | Total Usb Ports | 1 | | Wireless Compability | 802.11b | ## Product Details - **Brand:** HiLetgo - **CPU Model:** MediaTek MT8125 - **CPU Speed:** 80 MHz - **Memory Storage Capacity:** 0.5 MB - **Model Name:** NodeMCU LUA ESP8266 CP2102 ESP-12E ## Images ![HiLetgo 3pcs ESP8266 NodeMCU CP2102 ESP-12E Development Board Open Source Serial Module Works Great for Arduino IDE/Micropython (Large) - Image 1](https://m.media-amazon.com/images/I/618AQOe0NKL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Is this any different then the adafruit huzzah esp8266 breakout?** A: This unit can be programmed directly by connecting a micro-usb cable. 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 ### ⭐⭐⭐⭐⭐ A Dream for DIY LED Enthusiasts *by J***S on November 26, 2023* I recently purchased the HiLetgo 3pcs ESP8266 NodeMCU CP2102 ESP-12E Development Boards for a custom LED project I had in mind.
