For compact projects and control panels, we have created an all-in-one button/LED module.

Show device status, confirm a button press, or create an interactive interface - all of this and more from a single Troyka module.

When the button is depressed, the module will output a logical zero and when the button is released it will return a logical one. The LED indicator on the module is completely independent from the button, it has its own power and software.


The button is connected to the control electronics via two 3-pin jumper cables. The 3-pin jumper cables needed for the connection are included in the package.

The upper group of pins controls the button:

  • G is connected to ground
  • V2 is connected to to the power supply (3.3 - 5 V)
  • S is connected to the corresponding digital pin

The lower group of pins controls the LED:

  • L is connected to the controlling pin
  • V is connected to the power supply (3.3 - 5 V)
  • G is connected to the ground

There are several different ways to wire this module:

Troyka Shield. The most straightforward method. Connect the module to a pin group on Troyka Shield with the 3-pin jumper cable and you’re ready to interface with it from your Arduino.

Troyka Slot Shield. The best choice for quick prototyping. Using slots on the shield, you can get rid of cables. The module will be held securely in place using both pin headers.

Breadboard. For advanced use. Troyka pin headers have 0.1” spacing which is compatible with any breadboard. Simply wire the module like you would do with any IC.
