documented hardware platform
The public hardware reference describes a 100 mm × 100 mm board, ESP32-C3FH4, ST25R3911B NFC reader, RGB and charlieplex LEDs, sensors, buttons, USB edge connector, and CR2032 holders, and calls the PCB REV 2 dated 2025-05-05. This is linked as a technical documentation trail rather than a production audit or safety certification.
