The WeMos D1 Mini family of boards is one of the latest additions to the ESP8266-based IoT ecosystem. The WeMos D1 Mini Button Shield allows you to add a push button to your WeMos mini or mini Pro development boards. Using a tactile/push button (momentary switch) allows the user to interact with the ESP8266. For example push buttons are used to switch items in a menu, start/stop a measurement, and even reset the microcontroller or SoC.
The WeMos D1 Mini Button Shield is designed so that the button is connected to pin D3 on the WeMos D1 Mini. The other terminal of the push button is connected to Digital Ground. And so, to determine when the button is pushed, we set D3 as a Digital Input (with Internal Pull-up), and monitor when the input goes from Digital HIGH to Digital LOW.
What makes the WeMos family of development boards for the ESP8266 great is the availability of stackable, plug-and-play shields such as this WeMos D1 Mini Button Shield. Without much fuss, it's very easy to connect, control, and monitor a wide variety of electronic components to the ESP8266. The WeMos family is a great solution for building projects quickly using the ESP8266 SoC.
Different users have different applications for the WeMos shields, thus we've found that the easiest way to please everyone is to ship the boards with the headers unsoldered. Each board in this kit includes a pair of Male, Female, Long Female pin headers for you to choose. Soldering is required for installing the header pins!
