ESP8266 wifi module + NodeMcu v3

WiFi module, based on ESP8266 system. It has uploaded software NodeMCU which provides programming with the Lua script language. The system has 10 GPIO pins (each of them can be controlled by the signal PWM), I2C bus, 1-Wire, 10-bit analog-to-digital converter and PCB antenna. In addition, the board has the converter USB-UART (CH340) which allows to programm directly via USB port using the Arduino IDE environment.

Module dimensions: 58 x 30 mm, terminal pitch is 2.54 mm

Lua is a script language that can work independently or as an extension of the capabilities of other applications. It was implemented as a library of C language. It features a simple code, high performance and the possibility of transfering between platforms. Details on the home page of Lua.
