NodeMCU ESP32 Development Board

NodeMCU is an open source ESP32 development board and firmware based in the widely used ESP8266 -12E WiFi module. It allows you to program  the ESP8266 WiFi module with the simple and powerful LUA programming language or Arduino IDE. With just a few lines of code you can establish a WiFi connection and define input/output pins according to your needs exactly like arduino, turning your ESP8266 into a web server and a lot more. It is the WiFi equivalent of ethernet module. Now you have internet of things (iot) real tool. With its USB-TTL , the NodeMCU Development board supports directly flashing from USB port. It combines features of WIFI access point and station + micro-controller. These features   make the NodeMCU extremely powerful tool for Wifi networking. It can be used as access point and/or station, host a web server or connect to internet to fetch or upload data. Features Finally, programable WiFi module. Arduino-like (software defined) hardware IO. Can be programmed with the simple and powerful micro python, Lua programming language or Arduino IDE.  USB-TTL included, plug & play. 10 GPIOs D0-D10, PWM functionality, IIC and SPI communication, 1-Wire and ADC A0 etc. all in one board. Wifi networking (can be used as access point and/or station, host a web server), connect to internet to fetch or upload data. Event-driven API for network applications. PCB antenna.
