Nodemcu specifications

NodeMCU is an open-source Lua based firmware and development board specially targeted for IoT based Applications. It includes firmware that runs on the ESP8266 Wi-Fi SoC from Espressif Systems, and hardware which is based on the ESP-12 module.

What is NodeMCU and how it works?

NodeMCU is an open source platform based on ESP8266 which can connect objects and let data transfer using the Wi-Fi protocol. In addition, by providing some of the most important features of microcontrollers such as GPIO, PWM, ADC, and etc, it can solve many of the project's needs alone.

What is the range of NodeMCU?

Operating voltage range of ESP8266 is 3 to 3.3v. The NodeMCU board has inbuilt LDO voltage regulator which keep the voltage level at 3.3v.

How many bit is NodeMCU?

There's a 32-bit RISC processor clocked at 80MHz, along with a generous RAM complement and support for up to 16mb of external flash storage. The device is especially useful for IoT applications, thanks to its tiny footprint and built-in WiFi support.

Can NodeMCU work without Wi-Fi?

Which MicroController is used in NodeMCU?

The NodeMCU (Node MicroController Unit) is an open source software and hardware development environment that is built around a very inexpensive System-on-a-Chip (SoC) called the ESP8266.

Is NodeMCU a software or hardware?

The NodeMCU (Node MicroController Unit) is an open-source software and hardware development environment built around an inexpensive System-on-a-Chip (SoC) called the ESP8266.

Is NodeMCU IoT device?

NodeMCU is open source IOT platform with firmware which runs on ESP8266 WiFi SOC. During this workshop you can prototype your IOT project with some quite easy steps. The NodeMCU firmware is a companion project to the popular NodeMCU dev kits, ready-made open source development boards with ESP8266-12E chips.

Does NodeMCU have GPS?

NodeMCU	GPS module
3V3	Vcc
GND	GND
D1 (GPIO5)	RX
D2 (GPIO4)	TX

How many types of NodeMCU are there?

Types. There are two available versions of NodeMCU as version 0.9 & 1.0 where the version 0.9 contains ESP-12 and version 1.0 contains ESP-12E where E stands for "Enhanced".

Can NodeMCU run on 5V?

Nodemcu runs on 5V and 3.3V. There is already an LDO voltage regulator for 3.3V to keep the voltage constant. The NodeMCU is fueled through a Micro USB jack and a VIN pin (External Supply Pin).

Can NodeMCU work with 5V?

Nodemcu operates at 5v & 3.3V. For 3.3V there is already an LDO voltage regulator to keep the voltage steady at 3.3V. NodeMCU can be powered using Micro USB jack and VIN pin (External Supply Pin).

Does NodeMCU have IP address?

NodeMCU has Station (STA) mode using which it can connect to the existing wi-fi network and can act as an HTTP server with an IP address assigned by that network. NodeMCU gets IP from the Wi-Fi router to which it is connected. With this IP address, it can act as an HTTP server to which any wi-fi device can connect.

Is NodeMCU a sensor?

ESP8266 NodeMCU: BME680 Environmental Sensor using Arduino IDE (Gas, Pressure, Humidity, Temperature) The BME680 is an environmental digital sensor that measures gas, pressure, humidity and temperature.

Can NodeMCU run on 12V?

Using a 12V or above supply and loading the module's outputs/using wifi means it will run very hot - possibly even damaging it. Use, if possible, a 5V wall wart - temperatures will be much lower. NodeMCU is not an Arduino and I've seen stories about them burning up when supplied with voltage too high.

What are the disadvantages of NodeMCU?

Memory limitations. Less powerful. Processing power is weaker than the microcontroller.

Can NodeMCU act as hotspot?

In some cases, this might not be the best configuration (when you don't have a router nearby). But if you set the ESP8266 as an access point (hotspot), you can be connected to the ESP8266 using any device with Wi-Fi capabilities without the need to connect to your router.

How many sensors can be connected to NodeMCU?

The disadvantage of using Nodemcu alone is that, you can monitor only one analog sensor, as in Nodemcu ESP8266 Wifi Module we have only one analog pin A0.

How many ports are there in NodeMCU?

GPIO Pins ESP8266 NodeMCU has 17 GPIO pins which can be assigned to various functions such as I2C, I2S, UART, PWM, IR Remote Control, LED Light and Button programmatically. Each digital enabled GPIO can be configured to internal pull-up or pull-down, or set to high impedance.
