Here we use NodeMCU 1.0 (ESP12E Module).Ĭhoose your appropriate COM Port shown on your IDE.

In the ‘ Boards Manager‘ choose the exact NodeMCU Board Version.

To access the Wi-Fi Functionalities we need to install the ESP8266 Wi-Fi Library.īoard Settings and COM Port before uploading the code. This is a limited setup to run our NodeMCU without Wi-Fi. Choose the esp8266 by ESP8266 Community and Install it.Īfter rerunning the IDE you can able to see NodeMCU in Boards Manager of Arduino IDE. Now in the search bar type ‘esp8266’ and it will show the Libraries. This ESP8266 Boards Package will support NodeMCU, ESP32, Wemos, etcAs we have added the ‘Additional Boards Manager URL’ in the last step we can go ahead and search for ESP8266 in ‘Boards Manager’ tab. We can install the list of ESP boards in ‘Boards Manager’. Installing ESP8266 Boards in Boards Manager Step 2: Add the following URL in ‘Additional Boards Manager URLs’ field. Or you can download and install it from Arduino Website. Next, we need to configure Arduino IDE to add our NodeMCU to the ‘Boards manager’. Here you can able to see the driver is installed properly. Install the Driver Software by choosing 32-bit or 64-bit Installer.Īfter installation, connect the NodeMCU using MicroUSB Cable and open Device Manager. You can visit the website and download the Driver according to your operating system. Almost all NodeMCU Boards support CP2102 Driver. If you look at the backside of NodeMCU it shows which driver it supports. We will see how to install Drivers, Boards and Wi-Fi libraries in this tutorial. Code like Arduino, but interactively in Lua script. Advanced API for hardware IO, which can dramatically reduce the redundant work for configuring and manipulating hardware.Can be programmed with Arduino IDE (refer Pin mapping) or Lua Scripts.Wi-Fi Networking (can be used as an Access point, Station and a small server).10 GPIO D0-D10, PWM functionality, I2C, SPI, 1-Wire and ADC (A0).The Development Kit based on ESP8266, integrates GPIO, PWM, IIC, 1-Wire and ADC all in one board.You need to download and install the driver manually for the first time. Using a micro USB cable you can connect it to the PC without any additional power (for low power circuits). As we know the ESP8266 is a 3.3v Microcontroller it needs a 3.3v regulator to supply optimum power.Īdditionally, it has CP2102 USB Driver IC to communicate via USB with PC. Hence this board has built-in voltage regulators to provide optimum power to ESP8266 IC. The NodeMCU is based on ESP866 Series.Īs the name suggests it is a development board, it contains additional circuitry for Power supply USB, Communications, etc (Similar to an Arduino Uno is built around ATMEGA328 IC). Its predecessors are ESP-01, ESP8266-12E. NodeMCU is a popular Wi-Fi based Development board in IoT Projects.
