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. |
Examples of programs
- The indicator of missed calls
- Smart guardian of plants
- Feeder of animals
- Simulator of traffic signal
Pins
The system has soldered 4-pin slots to connectmodules and sensors from the Grove, which, in addition to the pins of the ESP system, also include the power supply in the form of 3.3 V voltage and GND mass.
