Feb 15, 2022 · I have included a detailed specification pin diagram of NodeMCU ESP8266 and Arduino UNO. After this article, you will learn how to use Arduino UNO and ESP8266 board with Arduino IDE and the technical difference between the two boards.

Apr 22, 2020 · NodeMCU can be powered using a Micro USB jack and VIN pin (External Supply Pin). It supports UART, SPI, and I2C interface. The NodeMCU Development Board can be easily programmed with Arduino IDE since it is easy to use. Programming NodeMCU with the Arduino IDE will hardly take 5-10 minutes.

Thus, we’ll learn the correct pin identification by doing the following: looking at the NodeMCU datasheet, knowing which of these pins work with digitalWrite, digitalRead, analogWrite, and analogRead, and understanding the boot more thoroughly. As I program more with Arduino IDE, I practically see the NodeMCU as an Arduino.

Jun 19, 2023 · The ESP8266 NodeMCU is equipped with a total of 17 GPIO pins, conveniently placed on the pin headers on both sides of the development board. These pins can be assigned various peripheral tasks, offering flexibility in their usage.

Mar 23, 2024 · NodeMCU esp8266 wifi module is an open-source, low-cost, low-power MCU (microcontroller unit) development board. It has 17 GPIO pins (11 are Digital I/O pins), out of which one pin is an analog pin, 4 pins support PWM, 2 pairs are for UART (UART0 and UART1), and supports 1x SPI and 1x I2C protocol.

The ESP8266 NodeMCU has 17 GPIO pins that can be assigned different functions by programming the appropriate registers. Each GPIO can be configured with internal pull-up or pull-down, or set to high impedance.
