The M5Stack Dual Button as the name states, has two buttons with different color. If the Button unit is not enough for your application needs, how about double it up to a pair? They share the exact same mechanism, button status can be detected by the input pin status by simply capturing the high/low electrical level. This unit communicates with M5Core through GROVE B port.
