Description

The module is based on ESP8266. It has the ability to connect to Wi-Fi and 1 digital port of inputs/outputs and 1 analog input and interfaces: UART, I2C. This version works with a voltage of 3.3 V, it has a microUSB connector to power the device. For programming, for example, by using the Arduino IDE, reqiured is USB-UART converter.

The ESP8266 controllerprovides communication with wi-fi network, thanks to the integrated controller, the system can be programmed via the Arduino IDEusing the USB - UARTconverter - details inthe user guide.
