【DESCRIPTION】
【ADVANTAGES】
| This ESP8266 Wifi chip based development kit is the easiest way to get started with ESP8266 and IoT in general. It is based on easy to use Lua scripting where you can simply command the hardware to perform variety of tasks like GPIO, PWM, I2C, WiFi etc just by writing simple script of a few lines.
| The ESP8266 NodeMCU CP2102 board has ESP8266 which is a highly integrated chip designed for the needs of a new connected world. It offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor.
| This board is pre-flashed with NodeMCU, a Lua-based firmware for the ESP8266 which allows easy control via a neat scripting language Lua, The ESP-12 Lua NodeMCU WIFI Dev Board Internet Of Things with ESP8266 is an all-in-one microcontroller + WiFi platform that is very easy to use to create projects with WiFi and IoT (Internet of Things) applications.
| Power to the ESP8266 NodeMCU is supplied via the on-board Micro USB connector. It has a built-in USB to serial chip upload codes, 3.3V regulator and logic level converter circuit so you can immediately upload codes and connect your circuits.
【APPLICATION】
| VoIP applications, IP camera, Baby monitor
| Sensor network, Internet controlled robot
| IoT (Internet of Things) Project solution, Cloud Connectivity
| Home automation and security, Home and industry-based wireless control
| The ESP8266 can be used as Station or Access Point or both combined
| Can be programmed for Arduino IDE or AT-commands or Lua Script
【Pin Connection】
[Power] Micro-USB: |NodeMCU can be powered through the USB port; 3.3V: Regulated 3.3V can be supplied to this pin to power the board; GND: Ground pins; Vin: External Power Supply
[Control Pins] EN, RST: | The pin and the button resets the microcontroller
[Analog Pin] A0: | Used to measure analog voltage in the range of 0-3.3V
[GPIO Pins] GPIO1 to GPIO16: | NodeMCU has 16 general purpose input-output pins on its board
[SPI Pins] SD1, CMD, SD0, CLK: | NodeMCU has four pins available for SPI communication.
[UART Pins] TXD0, RXD0, TXD2, RXD2: | NodeMCU has two UART interfaces, UART0 (RXD0 & TXD0) and UART1 (RXD1 & TXD1). UART1 is used to upload the firmware/program.
[I2C Pins] ~ : | NodeMCU has I2C functionality support but due to the internal functionality of these pins, you have to find which pin is I2C.
