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:
- Arduino Uno ATmega328P 2 KB RAM limit requires careful dynamic string and buffer management.
- SoftwareSerial with HC-05 is constrained to 9600 baud for stable telemetry.
- DFPlayer Mini requires MP3 audio files pre-loaded onto a micro-SD card.
