designed by Espressif Systems. The ESP8266 itself is a self-contained WiFi networking solution offering as a bridge from existing micro controller to WiFi and is also capable of running self-contained applications. This module comes with a built in USB connector and a rich assortment of pin-...
TheOUT +/OUTconnection remains. We connect the ESP8266 to this, but before that, we need thevoltage regulatorso that a constant 3.3V is output. This has 3 connections (VIN, VOUT, GND) and we connect it according to the following (diagram). The capacitor (shorter pin on GND): With th...

Nodemcu ESP8266 Development Board Serial wifi Module CH340G OLED Screen for Arduino IDE/Micropython CH340 Driver Module Product Features:1.This is an ESP8266 0.96 OLED board with all the features of a traditional ESP8266 module.2.Seamless integration with 0.96" OLED displays eliminates the need ...
NodeMCU has weird pin mapping. Pin numbers written on the board itself do not correspond to ESP8266 GPIO pin numbers. We have constants defined to make using this board easier: staticconstuint8_tD0 =16;staticconstuint8_tD1 =5;staticconstuint8_tD2 =4;staticconstuint8_tD3 =0;staticconst...
1. This is an ESP8266 0.96 OLED board with all the features of a traditional ESP8266 module.2. Seamless integration with 0.96 inch OLED display, eliminating the need for wires and breadboards.3. The board uses I2C to connect to the OLED display through the SDA (D6/GPIO14) and SCL (...
NodeMCU based ESP8266 has Hardware SPI with four pins available for SPI communication. With this SPI interface, we can connect any SPI enabled device with NodeMCU and make communication possible with it. ESP8266 has SPI pins (SD1, CMD, SD0, CLK) which are exclusively used for Quad-SPI comm...

ESP8266 NODEMCU UART to MQTT bridge What is it The purpose of this code is to make simple bridge between any UART enabled system (Arduino, etc) and MQTT broker over WIFI network. User should simply send and receive data from UART enabled application and also send and receive data by publis...
Important!While it shows 3.3V and the datasheet says so, the 3V pin is indeed 3V only! Connecting a 3.3V device won’t work so be aware. These are the boards that carry the “NodeMCU” name. But they are not the only ones featuring the ESP8266. SeeAdafruit HuzzahandWeMos D1 Mini....
