Description
Wi-fi module based on ESP8266 system. It has uploaded the NodeMCU software which provides the programming using the Lua scripting language. The system has 11 GPIO pins (each of them can be controlled by the PWM signal), I2C bus, 1-Wire, analog-to-digital converter. In addition, the board has the USB-UART converter which allows for the programming directly through the USB port using the Arduino IDE environment.
Lua is a scripting 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 has a simple code, high performance and the possibility to transfer between platforms. Details are on the Lua home page.
Module dimensions: 58 x 25 mm, pins pitch is 2.54 mm
| At the first start, we recommend to upgrade the firmware according to this instruction. |
