A display would be a great addition to the microcontroller and numeric keypad, so that the user of the device could easily verify the data entered.
Easy-to-mount keys
The component has 4 membrane keys (appropriately numbered), which can be easily fixed to any smooth surface (keyboard is self-adhesive).
The keyboard was designed to be as easy to connect as possible.

There are five wires - 4 corresponding to individual buttons and one power supply (5 V).
