M5Stack Mini Button Unit
Description
Unit Button is a compact single-button input unit for M5Stack projects. The Unit Button detects changes in the input pin's high and low voltage levels to determine the button state, making it a straightforward digital input module for interactive controls.
With an HY2.0-4P Grove interface, UIFlow and Arduino support, and two LEGO-compatible holes, the Unit Button is easy to connect, program, and mount. It is suited to lamp switch, remote control switch, and simple trigger input applications where a small physical button is needed.
Features
- Unit Button single-button input module for digital high/low state detection.
- HY2.0-4P Grove interface for quick connection to M5Stack controllers.
- Supports UIFlow and Arduino development workflows.
- Two LEGO-compatible holes for mechanical mounting.
- Compact 32 x 24 x 8mm Unit form factor.
- Useful as a physical trigger, switch input, or simple remote control button.

Input Behavior
The Unit Button reports the button state by detecting the voltage level on its input pin. This makes it suitable for simple binary input tasks where software only needs to read pressed or released state changes.
Development Options
The Unit Button can be used with UIFlow, Arduino examples, and the related EasyLoader demo, making it quick to test button state detection before integrating it into a larger M5Stack project.
