Known Engineering Constraints & Bench Boundaries
All projects are built from real bench testing and validated by automated static analysis and continuous integration. Note the following operational boundaries:
- SPI bus sharing between dual RC522 modules requires dedicated chip select (CS) pin handling.
- MariaDB credentials are parameterized via environment variables.
- SG90 servo latch operates on 5V external power rail.
