D1 Mini Button 1Button Shield Overview A compact singlebutton shield that plugs directly onto D1 Mini compatible boards to provide a reliable tactile input without wiring. Designed for quick prototyping and tidy final builds where a simple physical button is required. Key benefits Instant physical input: Adds a user button to projects without soldering or breadboard wiring. Space efficient: Compact form factor that mounts directly on the D1 Mini compatible board to save space. Easy to integrate: Uses the D1 Mini pinout so it works with existing sketches and libraries that read GPIO inputs. Durable and reliable: Mechanical tactile switch suitable for frequent presses, intended for everyday interaction. Main features Function: Single momentary tactile push button that presents a clean digital input to the host board. Compatibility: Fits D1 Mini form factor boards and compatible shields that use the same header layout. Installation: Plugs onto the headers of the D1 Mini compatible board for a secure connection with no additional wiring. Material and construction: Standard PCB shield with a tactile switch mounted for mechanical durability and consistent feel. Performance: Provides a straightforward, lowlatency input signal. Software debouncing recommended for results. Practical applications WiFi setup and pairing: Use the button to trigger configuration or enter setup mode during initial device deployment. Local control and overrides: Implement a physical on device control for toggling relays, modes, or scenes in an IoT system. User interaction during development: Useful for resetting counters, stepping through menus, or triggering test routines while prototyping. Why choose this shield Minimal and focused design provides a single, well integrated user input without adding bulk. Direct compatibility with D1 Mini form factor boards reduces integration time and keeps projects neat. Simple to use for developers and hobbyists who need a reliable physical button for control, configuration, or testing. Notes Software debouncing required for clean input when reading the button state. Check the host board pin mapping to assign the button to the desired GPIO.
