    • A Dream for DIY LED Enthusiasts
Size: Pack of 3
I recently purchased the HiLetgo 3pcs ESP8266 NodeMCU CP2102 ESP-12E Development Boards for a custom LED project I had in mind. After spending some quality time with these boards, I'm thoroughly impressed and feel compelled to share my experience. First off, the ease of use is remarkable. As someone who appreciates the nuances of DIY electronics but isn't a seasoned expert, I found the setup process to be straightforward and user-friendly. The boards were compatible with my existing software setup, and I didn't encounter any significant hurdles during the initial programming phase. The real magic happened when I started using these boards for my custom LED setups. The ESP8266 NodeMCU's ability to effortlessly drive and control LEDs was a game-changer. Whether it was for basic lighting projects or more complex, multi-colored LED arrays, these boards performed flawlessly. The Wi-Fi capability is also a huge plus, offering the convenience of wireless control, which is perfect for smart home applications. I must also commend the stability and reliability of these boards. Throughout my projects, they maintained consistent performance without any significant glitches or overheating issues. This reliability is crucial when you're knee-deep in a project and need your components to perform without a hitch. In terms of value for money, this pack of three is an absolute steal. The quality and functionality you get for the price are unmatched, making these boards a must-have for anyone into DIY electronics, especially LED projects. To sum up, the HiLetgo ESP8266 NodeMCU Development Boards are a fantastic investment for anyone looking to delve into custom LED projects or general IoT applications. Their ease of use, reliability, and excellent value make them a standout choice. I highly recommend these to both novices and seasoned tinkerers alike! ... show more

    • ESP8266 WiFi Module Powers LED Project with Ease!
Size: Pack of 3
I recently used this module in a project to control LED lights, and I have to say, it worked incredibly well. One of the best things about the ESP8266 is its low price point. Despite being packed with features, including a built-in WiFi chip and support for the Arduino IDE, the module is incredibly affordable, making it a great choice for hobbyists and professionals on a budget. In my LED project, I used the ESP8266 to control the lights via a web interface. The module responded quickly and reliably to all of my commands, and I was able to create a simple web page that allowed me to turn the lights on and off, and adjust their brightness. Another great thing about the ESP8266 is its compact size. The module is small enough to fit in just about any project, making it incredibly versatile. Despite its small size and low price, the module is also quite powerful, with plenty of processing power and memory to handle a wide range of tasks. ... show more

    • Avoid WLED v0.14.1 and install v0.13.3 instead!
Size: Pack of 3
I used the web installer to instal WLED on my devices. At first I installed WLED v0.14.1 and the UI took forever to load or never loaded, it was hard to acquire wifi, and the devices would go often offline. I was ready to trash them. I then installed WLED v0.13.3, and voila! The devices now work perfectly (but I haven't connected any lights yet.) Lastly, everyone who had problems finding the right microUSB cable was right. I tried four cables before one worked. ... show more

    • Great Value for an ESP8266 NodeMCU board
Size: Pack of 3
Once the drivers were installed - ran into a couple of glitches but essentially my second attempt at loading the drivers worked. Once past that - the rest was a breeze. I was able to build several prototypes to test out the functionality. Board is well made - can't see issues with the soldering or pins. HiLetGo is becoming my go to seller for Arduino related products. Most of the technical details are already listed in other reviews. One thing I found out (was unaware) - if you power the board via USB then the Vin pin provides 5V output for other sensors. Can't provide high current in my testing it easily tolerated a few milliamps. I used three boards to build #1. Web Server with sensors sending data to remote #2. Web Client with OLED SSD1315 display and #3. Energy Meter using an INA219 module reporting current and voltage. To use the SDA & SCL pins for serial communication for LCD or OLED displays for example, you need the following in your sketches: #include <Wire.h> #define I2C_SDA 4 /// ESP8266 NodeMCU SDA pin GPIO4 = D2 #define I2C_SCL 5 /// ESP8266 NodeMCU SCL pin GPIO5 = D1 // add in your setup section Wire.begin(I2C_SDA, I2C_SCL); /// Identify SDA & SLC pins for ESP8266 NodeMCU Some additional information for pin mapping from my notes. Hope it's helpful for others. D0 = GPIO16; Wake [connect RST to D0] D1 = GPIO5; SCL Serial Clock - D2 = GPIO4; SDA Serial Data - #include Wire.h & Wire.begin(SDA, SCL); D3 = GPIO0; Using 0 or D3 both accepted D4 = GPIO2; using 2 or D4 both accepted D5 = GPIO14; D6 = GPIO12; D7 = GPIO13; D8 = GPIO15; D9 = GPIO3; D10 = GPIO1; LED_BUILTIN = GPIO16 (auxiliary constant for the board LED, not a board pin); ... show more

    • OTA fails if mixed is turned on in my router
Size: Pack of 3
I bought them to play with earlier this year. Winter ended and I just got back to playing with them. Last night I was trying to get OTA programming working but it would fail at 2%. Searching github I found a note that someone has a Linksys wrt3200acm router and had to set it to 802.11g only to get ota working. OTA worked fine after I did the same. Mentioning it in case you are doing some head banging trying to get yours working. ... show more

    • Easy to setup and use
Size: Pack of 3
Only tried one out of the lot, but overall was very easy to plugin power (micro usb cable), fit well into breadboard, and easy to connect and config with the Arduino IDE. One note: I tried two cables. The first one worked fine, but the 2nd one did not. The first was a "higher" quality cable, so not sure what specifically is required. Would recommend. ... show more
