Description
Wi-fi module based on ESP-12E ESP8266. It has uploaded software NodeMCU which enables 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 (CP2102) which allows to programm directly via USB port using the Arduino IDE environment. Has 4 MB of Flash memory.

Module dimensions: 49 x 25 mm, lead's 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 transfer between platforms. Details onthe home page of Lua.
