Description

The module is compatible with Arduino-based on wi-fi ESP8266. It has the ability to connect to a wireless network and 11 digital inputs/outputs, 10 channels of PWM, 1 analog input, as well as popular communication interfaces. This version works with a voltage of 3.3 V and has a microUSB connector for programming.

D1 R2 WiFi ESP8266 - zgodny z WeMos i ArduinoThe ESP8266 controller provides communication with a wi-fi network, thanks to the integrated controller, the system can be programmed via the Arduino IDE through the microUSB cable (sold separately). Board is also working with NodeMCU.

First run

  1. Download and install the Arduino IDE version 1.6.7 from: www.arduino.cc
  2. Start the Arduino IDE, selectFile - > Settings
  3. In place "Additional URL adresses" for the manager of boards, specify:
    http://arduino.esp8266.com/stable/package_esp8266com_index.json
  4. SelectTools -> Board -> Manager of boards
  5. Install the module ESP8266 Community (probably, at the bottom of the list)
  6. Since now, boards from the WeMos will be available from the Menu:Tools -> Board

 

 

Description of the programming of the board using the Arduino IDE can be found on the website of the manufacturer.

Examples of programs are available in the GitHub service.
