Description
V3 Wireless module NodeMcu 4M bytes Lua WIFI Internet of Things development board based ESP8266 esp-12e for arduino Compatible
Introduction:
The NodeMcu is an open-source firmware and development kit that helps you to
Prototype your IOT product within a few Lua script lines.
For more details, please visit https://github.com/nodemcu/nodemcu-firmware/wiki/nodemcu_api_en
Features:
- Open-source
- Interactive
- Programmable
- Low cost
- Simple
- Smart
- WI-FI enabled
- Ard–uino-like hardware IO
- Advanced API for hardware IO, which can dramatically reduce the redundant work for configuring and manipulating hardware.
- Code like ard–uino, but interactively in Lua script.
- Event-driven API for network applicaitons, which faciliates developers writing code running on a 5mm*5mm sized MCU in Nodejs style.
- Greatly speed up your IOT application developing process.
Specification:
- The Development Kit based on ESP8266, integates GPIO, PWM, IIC, 1-Wire and ADC all in one board.
- Power your developement in the fastest way combinating with NodeMCU Firmware!
- USB-TTL included, plug&play
- 10 GPIO, every GPIO can be PWM, I2C, 1-wire
- FCC CERTIFIED WI-FI module(Coming soon)
- PCB antenna

I’m happy that I got it at very reasonable price

Good one for controlling relay module, I have used it to control 4 channel relay module, but i guess 8 channel relay module can also be controlled without any issues as such. If you are using this NodeMCU WiFi Board to control 4 channel relay module then go for REES52 Optocoupler 4 Channel 5V Relay Module. To make all the relays work perfectly with the REES52 NodeMCU WiFi Board remove the jumper from the Vcc and JD Vcc of the relay and power the JD Vcc pin of the relay from the VU pin of the REES52 NodeMCU WiFi Board (The VU pin of the NodeMCU board actually gives a 5V supply), leaving the Vcc point as it is. Next, connect the GND and Vcc along the input points of the relay board from GND and 3V of the NodeMCU. The input pins on the relay board can be connected to any four of the 8 available D0-D8 pins.

Really awesome product just plug upload your sketch using Arduino IDE and it works fine and on time delivery is great.
gurubaran –
best mcu at low price ,and it also contains wifi ,which is double profit ,because wifi module cost is almost same as the total cost of this product
