basics of the ESP-12E NodeMcu V3 module

 Already finished, and so forth!

In addition, I take this chance to thank most of the buyers for their service and also their great comments in the Tindie store, it is pleasant to find that the product is of use for you. I'm only a little less available at the moment from the area however that I handle time to time for emergencies, I really apologize.

PS: Look at the remapping of this Serial on the brand new Raspberry PIs (watch this article )

Intro

to Day, we'll examine the basics of the ESP-12E NodeMcu V3 module. We will also find the fundamental connection scheme for blinking-led with Arduino IDE after in this particular tutorial.

Q>> What is an ESP-12E NodeMcu V 3 module?

A>> NodeMCU can be a LUA based interactive firmware for both Expressif ESP8622 Wi-Fi SoC, as well as an open source hardware board which, unlike the 3 ESP8266 wifi modules, features a CP2102 TTL to USB chip for debugging and programming, is breadboard-friendly, also can simply be powered via its microusb port.

This module is one of the most affordable available wifi-modules available in market. V3 or even Version3 is the newest version of this module.

For manufacturers, using ESP-12 module, rest assured, 12E is not any different from its precursor. The only difference: 6 extra GPIOs are present in ESP-12E

Headers: 15-pin header together with usage of GPIOs, SPI, UART, ADC, and power pins.

Power: 5V through Micro-usb jack

Hardware Components demanded:

ESP 12E NodeMcu V 3, A breadboard for setting the LED and a couple of Jumper cables to attach them.

This NodeMcu breakout module has been built around ESP-12E plank

Software required: Arduino (In the next tutorial, we'll see just how to work in Lua)

But, as most of people are knowledgeable about ArduinoIDE, let's ponder upon it for a short time.
