WeMos D1 mini ESP8266 NodeMcu Lua Board

This small microcontroller is very powerful and also has a WLAN radio module. The module is compatible with the Arduino IDE and can be programmed right away. With the ESP8266, you can easily connect your projects to the Internet. The board is often used for IoT (Internet of Things) applications. For example, you can easily connect your data logger to the Internet and log the data to a cloud.

The WeMos D1 has a micro-USB connection for programming and power supply. Since the ESP8266 is purely a 3.3V controller, you may only operate all inputs and outputs with 3.3V! If you still want to connect or control something with 5V, you need to use a logic level converter, which you can also find in our shop.

When programming with the Arduino IDE, you need to be aware that you can control the pins in two different ways.

Variant 1 via the labeled name on the board:

For example, let's take output D1, you can switch the output with the following command digitalWrite(D1,HIGH)

Variant 2 via the GPIO number

Here you control the output D1 using the GPIO number. In our example, the D1 is the GPIO05. So the following command digitalWrite(5,HIGH)

First, you need to install this board under the Board Manager in the Arduino IDE. You will find the board under the name "esp8266". If you can't find the board, you must first add it under File=>Preferences=>Additional Boards Manager URLs: http://arduino.esp8266.com/stable/package_esp8266com_index.json. Then under Tools=>Boards=>Boards Manager, you can search for and install the ESP8266. Once you've done that, you'll find various ESP8266 boards that you can select (select WeMos D1 R2 & mini for this board).

If you have questions or problems with controlling it or suggestions for the product description, just send us an email or use the review function. We're happy to help.
