Custom Macropad DIY - Homemade PCB

This project is a completely homemade macropad, from design to final use.

It includes:
- A 3×3 keypad (9 keys)
- A clickable rotary encoder
- An independent power button
- An integrated RGB LED to display the active configuration

The firmware is written in CircuitPython and allows:
- To use multiple configurations (maps)
- To launch applications
- To control volume and media
- To lock or shut down the PC

The mechanical and electronic design was carried out over approximately 3 months, with a learning objective.
