Quick start (Altium Designer)

A — Use the compiled Integrated Library (fastest)

1. View → Panels → Components → Installed → Install From File
2. Select RFID.IntLib
3. Place → Component, search for MFRC522 / RC522

B — Build from the Library Package (recommended for edits)

1. Open RFID.LibPkg in Altium
2. Review symbol ↔ footprint links and parameters
3. Right-click the library project → Compile Integrated Library to regenerate .IntLib

C — Raw libraries

Add RFID_RC552.SchLib and RFID_RC552.PcbLib to your project (or install via the Components panel).
