We’ll support both: a local Wi‑Fi web portal for universal access and a BLE/Wi‑Fi app interface for a polished experience, enabled only after fingerprint authorization. For the first version, should I design a custom compact PCB, or a module-based prototype using ESP32-C6, TFT, fingerprint, and charger breakout boards?

I’ll target a compact custom handheld PCB with ESP32‑C6, internal microSD, 1.3-inch TFT, FPC2534 fingerprint/touch navigation, LiPo charging, and wireless file access. This is a different product from the current environmental-sensor project—should I build it as a new Flux project?

I’ll create a separate project for the compact wireless file vault, then carry the agreed hardware requirements into its design brief.

Created the new project: ESP32-C6 Wireless Fingerprint File Vault. I also started the specification and initial schematic work there, including the ESP32-C6, internal microSD, TFT, fingerprint navigation, LiPo power, and wireless-access security plan.
