Regarding this, which NodeMcu is best?

Best ESP8266 Boards Comparison

ESP-01 ESP-12E NodeMCU
Links Banggood Amazon.com Aliexpress Banggood Amazon.com Aliexpress
GPIOs 4 (including TX and RX) 11
ADC Pins 1 1
Flash Memory 1MB (upgraded version) 4MB

Also Know, is esp32 reliable? As Evgenios Skitsanos says, it's very reliable. That's only the chip, however. Things that will make it very unreliable are firmware and anything connected to it. Despite the maker style of the Arduino platform, in the case of the ESP32 it sits on top of the ESP IDF, Espressif's official offering.

Also to know is, what is difference between NodeMcu and esp8266?

The 30 pin ESP32 can be reprogrammed and has both wifi and bluetooth. NodeMcu is software that comes installed in a ESP8266 nd uses the Lua programming language but the ESP8266 that comes with NodeMcu can be reprogrammed via the Arduino IDE.

Is esp8266 secure?

Some devices, like the ESP8266, can be made to perform secure connections, but only when they are directly programmed. This can be undesirable if plenty of GPIO and peripherals are required. For example, the ESP8266 only has one analogue read input.

Is NodeMCU a microcontroller?


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.

Can esp8266 replace Arduino?

The Arduino Uno board and the ESP module are not the same, but as long as the GPIO of the ESP8266 provides the hardware that you need for your application it will work. As you noticed, it can be added as a board type to the Arduino tool which makes it a lot easier for hobiests to play with it.

Which controller is used in NodeMCU?

NodeMCU is an open source IoT platform, whose firmware runs on Espressif's SoC Wi-Fi ESP8266, based on the ESP8266 nonOS SDK. Its hardware is based on the ESP-12 module. The scripting language is Lua which allows to use many open source projects like lua-cjson and spiffs.

Is esp8266 a microcontroller?

ESP8266. The ESP8266 is a low-cost Wi-Fi microchip, with a full TCP/IP stack and microcontroller capability, produced by Espressif Systems in Shanghai, China. This small module allows microcontrollers to connect to a Wi-Fi network and make simple TCP/IP connections using Hayes-style commands.

What is NodeMCU in IoT?

NodeMCU is a low-cost open source IoT platform. It initially included firmware which runs on the ESP8266 Wi-Fi SoC from Espressif Systems, and hardware which was based on the ESP-12 module.

How many pins are in esp8266?


The ESP8266 has 17 GPIO pins (0-16), however, you can only use 11 of them, because 6 pins (GPIO 6 - 11) are used to connect the flash memory chip. This is the small 8-legged chip right next to the ESP8266. If you try to use one of these pins, you might crash your program.

Does NodeMCU have Bluetooth?
