Review: Size and Wi-Fi Capability Awesome - I recently learned how to connect a variety of different types of inexpensive sensors to a NodeMCU ESP8266 and use its Wi-Fi capabilities to transmit sensor information to other Wi-Fi connected operating systems like Android and Windows etc. These little NodeMCUs are awesome and have been very reliable. I have used at least a dozen of them in different small hardware projects. None of these MCUs have failed yet. Some of the projects that I have used them in include: 1. Use a motion sensor to automatically turn my desk fan on and off when I sit down or leave my desk area. That project used NodeMCU, heat sensor, relay, fan, lcd display 2. Use a DC volt sensor and NodeMCU to send messages to my cell phone when my car battery is weak. That project used DC voltage senso, NodeMCU, IFTTT technology to get text msg to my cell phone. 3. Use switch and NodeMCU to send message to my cell phone when yard gate is opened and closed. 4. Used weight scale sensor with NodeMCU to weight items ranging from cotton ball to bowling ball. 5. Used Text-to-Speech module with NodeMCU to create a Voice Server so my various NodeMCU projects can use Wi-Fi to send messages to the Voice Server to speak. 6. Use temperature probe and NodeMCU to create a thermo logger that records temperature changes on a microSD memory card and can transmit the temperatures in a web page etc. It is fun and fairly easy to create a variety of different types of smart switches using different sensors, relays and these NodeMCU ESP8266 chips. Review: solid built 8266 12-E boards - These 8266 12-5 Node-EMCU boards are a great buy for the price. These allowed me to get a few IoT projects off the ground. As I get deeper into the project I am looking into switching to the V1 8266 boards as they are smaller and would probably be more then sufficient for this project. The Pros - These boards are easy to set up, configure, and get working for ESP-8266 projects. Easy to use, headers already installed. The Cons - The board seems with be missing a clear layout guide. The top and bottom have different pin names. I was able to figure it out but a clearer pinout on the board would be helpful. Over all I would recommend these boards for anyone looking to get into Ardunio and or IoT projects that require wifi. ## Features - The controllers are easy to program by using the CP2102-USB interface without having to press the flash and reset buttons before each flash operation. - The development board has integrating GPIO, PWM, IIC, 1-Wire and ADC all in one board. Support smart link smart networking. - The fast and affordable technology for WiFi. Make your development the fastest way combined with firmware for NodeMcu. - Modern, state-of-the-art LUA technology. It is an integrated unit with all available resources on board. It's very easy for Arduino projects or any development board with I / O pins. - Modern Internet development tools can use the built-in API to instantly put your idea on the fast track. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07HF44GBT | | Best Sellers Rank | #4,319 in Single Board Computers (Computers & Accessories) | | Brand | KeeYees | | Built-In Media | 3 x Development Board | | CPU Manufacturer | Espressif | | Connectivity Technology | Wi-Fi 802.11b/g/n, UART/GPIO | | Customer Reviews | 4.6 out of 5 stars 1,451 Reviews | | External Testing Certification | Não aplicável | | Included Components | 3 x Development Board | | Item Dimensions L x W x H | 1.89"L x 1.01"W x 0.51"H | | Manufacturer | KeeYees | | Mfr Part Number | Na | | Model Name | ESP8266 ESP-12E | | Model Number | 8541549622 | | Operating System | Lua | | Processor Brand | Espressif | | Processor Count | 1 | | RAM Memory Technology | LPDDR3 | | Total Usb Ports | 1 | | UPC | 705883356144 | | Unit Count | 1.00 Count | | Wireless Compability | 802.11b | ## Product Details - **Brand:** KeeYees - **Connectivity Technology:** Wi-Fi 802.11b/g/n, UART/GPIO - **Included Components:** 3 x Development Board - **Model Name:** ESP8266 ESP-12E - **Operating System:** Lua ## Images ![3pcs ESP8266 ESP-12E Development Board WiFi WLAN Wireless Module CP2102 for NodeMCU for ESP-12E for Arduino - Image 1](https://m.media-amazon.com/images/I/61ffhYwoLkL.jpg) ![3pcs ESP8266 ESP-12E Development Board WiFi WLAN Wireless Module CP2102 for NodeMCU for ESP-12E for Arduino - Image 2](https://m.media-amazon.com/images/I/61DHNv-0fGL.jpg) ![3pcs ESP8266 ESP-12E Development Board WiFi WLAN Wireless Module CP2102 for NodeMCU for ESP-12E for Arduino - Image 3](https://m.media-amazon.com/images/I/71zDVlW3OjL.jpg) ![3pcs ESP8266 ESP-12E Development Board WiFi WLAN Wireless Module CP2102 for NodeMCU for ESP-12E for Arduino - Image 4](https://m.media-amazon.com/images/I/61a4NnSQYEL.jpg) ![3pcs ESP8266 ESP-12E Development Board WiFi WLAN Wireless Module CP2102 for NodeMCU for ESP-12E for Arduino - Image 5](https://m.media-amazon.com/images/I/51irArYra2L.jpg) ## Questions & Answers **Q: When i connect it to the usb port on my windows 10 computer, i do not get a new com port. anyone else have this issue?** A: As others have suggested, installing the serial interface driver is necessary. The driver you are looking for is the CP2102 driver. A google search for CP2102 driver should bring you to it. The first link that appears, at silabs.com. it's the "CP210X USB to UART Bridge VCP" driver. This is required for windows to create the virtual com port (VCP). Once installed, you will see a COM port assigned in Device Manager under Ports and Communications section. This will be the COM port you select in Arduino IDE or whatever flasher you use, such as esptool. Other details: - A data cable is necessary (not just a charging cable). - It does NOT show up or appear as "another memory drive" to Windows. You will only see the COM port, because the only part of the board directly exposed to Windows is the serial interface chip (CP2102). **Q: do i need to use step down converter or can i connect 12v right to vin?** A: Hello, the working voltage of the ESP8266 module is 3.3v to 5V, you need to use a voltage regulator to stabilize the voltage to 5V. **Q: can not upload a sketch with arduino ide ?** A: Assuming you’ve got the correct USB-to-Serial drivers installed already, you’ll then need to add the board profile for this device. It’s a JSON document which you can easily find by doing an internet search for “esp8266 arduino board profile”. Add the URL to that json doc in the Arduino IDE preferences -> Additional boards manager URLs. Then, bring up the Board Manager (Tools -> Board -> Board Manager…) and search for esp8266. Select that result and click Install. Now you can select the correct board profile under Tools -> Board -> esp8266 -> NodeMCU 1.0 (ESP-12E Module). Finally, select the correct port. For example, on the Mac, you’d select Tools -> Port -> /dev/cu.SLAB_USBtoUART **Q: Is a0 adc analog pin on this board 3.3v compatible, or is it only 1v compatible? in other words, does it scale 3.3v to 1v for the 8266 native chip?** A: The nodemcu boards include a voltage divider to scale the 3.3v to 1v. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Size and Wi-Fi Capability Awesome *by L***N on April 12, 2022* I recently learned how to connect a variety of different types of inexpensive sensors to a NodeMCU ESP8266 and use its Wi-Fi capabilities to transmit sensor information to other Wi-Fi connected operating systems like Android and Windows etc. These little NodeMCUs are awesome and have been very reliable.

Being able to program directly via USB is a huge bonus, no level shifters or pushing buttons. No problems programming with either the Arduino IDE or VS Code/PlatformIO. Wifi works well and easy to set up using the WifiManager library. Consider this a huge step up from Arduino in terms of capacity and speed with the bonus of built in wifi. Prefer that the pins not be soldered (drop a star). They are hard to remove and maybe one device gets stuck in a breadboard but real projects need wires soldered which means removing the pins. Final thought: great for the price but given the number of ESP-32 devices now available for not more, I would probably pay a little extra for a much more powerful device. ## Frequently Bought Together - KeeYees 3pcs ESP8266 ESP-12E Development Board WiFi WLAN Wireless Module CP2102 for NodeMCU for ESP-12E for Arduino - BINZET DC Converter Step Down Regulator 5V Regulated Power Supplies Transformer Converter (5V 3A 15W) - HiLetgo 120pcs/3x40pcs Breadboard Jumper Wires Prototype Board Dupont Wire Male to Male, Male to Female, Female to Female, 2.54mm to 2.54mm 20CM Wires Assortment Kit for Arduino Raspberry PI DIY --- ## 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.sc/products/88401312-3pcs-esp8266-esp-12e-development-board-wifi-wlan-wireless-module](https://www.desertcart.sc/products/88401312-3pcs-esp8266-esp-12e-development-board-wifi-wlan-wireless-module) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-05-17*
