Nodemcu esp8266 pinout

About the Nodemcu ESP8266 Pinout: NodeMCU ESP8266 Wifi Module 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.

How many pins are there in NodeMCU ESP8266?

GPIO Pins NodeMCU/ESP8266 has 17 GPIO pins which can be assigned to 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.

How do I use ESP8266 GPIO pins?

Now, connect the ESP8266 using these instructions:

VCC will be connected to the 3.3V power supply.
GPIO0 and GPIO2 are general purpose digital ports.
Rx: Goes to Arduino pin0 (But needs a voltage adjusting)
CH_PD: Chip enable. ...
RST: Reset. ...
GND is ground.
Tx: Goes to Arduino pin1.

Is NodeMCU and ESP8266 same?

NodeMCU is a microcontroller development board with wifi capability. It uses an ESP8266 microcontroller chip.

What is NodeMCU ESP8266 used for?

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.

Does ESP8266 have 2 cores?

ESP8266 is based on a Tensilica L106 32-bit RISC processor ref which is single-core processor and thus you can't do real multiprocessing on it.

What pins to use ESP8266?

The pins used as SPI in the ESP8266 are:

GPIO12: MISO.
GPIO13: MOSI.
GPIO14: SCLK.
GPIO15: CS.

Is there 5V output in NodeMCU?

There is indeed a VU pin, and yes! It has 5V!

What is NodeMCU GPIO pin?

General-purpose input/output (GPIO) is a pin on an IC (Integrated Circuit). It can be either an input pin or output pin, whose behavior can be controlled at the run time. NodeMCU Development kit provides access to these GPIOs of ESP8266.

Are GPIO pins AC or DC?

The GPIO pins will have an output voltage of close to 0V or close to 3.3V, which allow direct current (DC) to flow, either out or in.

Can ESP8266 work on 5V?

Some people state that ESP8266 is tolerant of 5 V logic levels on its GPIOs, while others vehemently disagree, pointing at the datasheet-stated 3.6 V maximum.

What are the 3 modes of ESP8266?

The ESP8266 has three modes; mode 1 which is “Station” mode, mode 2 which is “Access Point” mode, and mode 3 which is “AP + Station” mode where the device can act as a WiFi client and access point simultaeously.

Can I hack Wi-Fi using NodeMCU?

Now, connect your laptop or smartphone with Access Point created by NodeMCU. Name of AP is “pwned” and password is “deauther” These are default name and password. 9. Click on the WiFi network which you want to Jam.

How do I program ESP8266 directly?

Wiring it up

Connect 3V of the NodeMCU to VCC of the ESP8266.
Connect GND to GND.
Connect TX of the NodeMCU to TX of the ESP8266 (This is different than the previous step)
Connect RX of the NodeMCU to RX of the ESP8266.
Connect D3 of the NodeMCU to GPIO 0 of the ESP8266 (D3 is GPIO 0 of the ESP8266)

Why ESP8266 is called NodeMCU?

The name "NodeMCU" combines "node" and "MCU" (micro-controller unit). Strictly speaking, the term "NodeMCU" refers to the firmware rather than the associated development kits. Both the firmware and prototyping board designs are open source. The firmware uses the Lua scripting language.

Which chip 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.

Can I use ESP8266 without Arduino?

Introduction: ESP8266 Web Server (Without Arduino) A few weeks ago I've created a project with an ESP8266 called: ESP8266 Web Server without an Arduino. That's exactly what you're going to build, if you follow all the steps in this Instructable. It's amazing what you can do with this $4 WiFi Module.

What is the range of NodeMCU ESP8266?

The module has a wireless WiFi transceiver operating in an unlicensed frequency range of 2400-2484 MHz in the IEEE 802.11 b/g/n standard, with support for TCP/IP communication protocol stack and WiFi security including WAP3.

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.
