Modular system designed to securely hold a circular Chipolo tracker and allow its use in different scenarios through dedicated interchangeable mounting bases. The project uses a shared enclosure structure to house the Chipolo, secured with screws, while different mounting methods are achieved simply by replacing the support base. This design is inspired by this excellent Apple AirTag project.

Modular Design

• the main body that holds the Chipolo is shared across multiple variants
• different attachment methods are achieved by replacing only the base
• the carabiner version uses a dedicated separate base

This approach provides:

• simplified maintenance
• reduced number of unique components
• the ability to easily develop additional compatible configurations
