User manual: Please get the link from the product description below. The chip model: CP2102. B01IK9GEQG Test Video: https://www.youtube.com/watch?v=Gh_pgqjfeQc; Firmware link: https://github.com/nodemcu/nodemcu-firmware; Data download access to the website: http://www.nodemcu.com; Makerfocus nRF24L01+ and ESP8266 ESP-01 Breadboard Breakout Adapter Board is come for free, it can compatible with "nRF24L01+ " and ESP8266 ESP-01. If you need more information about it, pls refer to: https://www.amazon.com/dp/B01N5AK6E1. ESP8266 is a highly integrated chip designed for the needs of a new connected world. It offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor. ESP8266 has powerful on-board processing and storage capabilities that allow it to be integrated with the sensors and other application specific devices through its GPIOs with minimal development up-front and minimal loading during runtime. Its high degree of on-chip integration allows for minimal external circuitry, and the entire solution, including front-end module, is designed to occupy minimal PCB area

I don't understand all the good reviews.

Tried to order them twice, 4 pieces each time (2x2 pieces). Any of them just won't work in an Arduino environment. I have dozens of ESPs (8266 and 32) that I've programmed to work with smart things. They all perform great. These just won't work even if flashed with NodeMcu 1.0 firmware. They get stuck in a reset loop OR just return random characters as long as the baud rate is set correctly. However, there are many good reviews here! Then I must be missing something! What's so special about the

Pros
  • Good product for the price
Cons
  • Obsolete model

Great boards! Once you figure them out.

These boards are incredibly profitable! The built-in Wi-Fi makes creating IoT projects extremely easy. There are a few issues I struggled with initially: - The pin numbers are a bit confusing, if you're programming with the Arduino IDE, paste this code at the top of your sketch. to convert the Dx pin numbers printed on the board to pin numbers that the Arduino recognizes. data)#define D3 0#define D4 2 // Like "LED_BUILTIN", but with inverted logic#define D5 14 // SPI SCK Bus (clock)#define D6โ€ฆ

Pros
  • Easy to use
Cons
  • Some bugs

Great module to use with Arduino IDE

I've ordered two of these. Both are going very well. I'm using one as a wireless web server to get the time from the server to set the clock on a nixie tube. I can also control the clock functions from the webpage via the two-wire I2C interface. The other block is connected to the Neopixel RGB LED ring with three wires. The module receives information about the local weather conditions and displays an LED animation corresponding to the weather conditions. It looks like the 3.3V regulator isโ€ฆ

Pros
  • This is awesome
Cons
  • Modern

Finally deserved!

This product is seriously lacking in documentation. After a few days of fiddling, I finally got it working using the Arduino environment. To help those who are having trouble, here are the steps required to get working with the Arduino programming environment. 1) Download the latest version of the Arduino environment (use google). I'm using 1.8.3 on Windows 7.2) Follow the instructions on sparkfun to install 8266 in an Arduino environment. Google "sparkfun install 8266 guide" and it should beโ€ฆ

Pros
  • Satisfied so far
Cons
  • Don't know

Not a great performance but phenomenal support!

Wanted to try these boards because I have prototyped several different NodeMCU clones and I have to say that the fit and finish of the board makes them not worth it. The connector pins aren't directly soldered, so you have a hell of a time plugging them into a breadboard. Also, the mechanical shielding of the GPIO pins is poorly done and they are difficult to read on the board. I haven't downloaded them yet, but I have to say I'm not happy with how cheaply they're put together. ***Update***โ€ฆ

Pros
  • Free for educational purposes
Cons
  • Only available in black
