From the project
Self-hosted ESP32-S3 smart doorbell with a custom PCB, Raspberry Pi gateway, and web dashboard
The routed KiCad schematic and PCB are the source for Rev C connections, footprints, and population intent. The Rev C design uses an ESP32-S3-WROOM-1-N16R8, an OV5640 24-pin camera connector, MCP73871 battery charging and power path, TPS63802 3.3 V regulation, and a GPIO-controlled camera power switch.
The Rev C ordered release identifies the exact Gerber, JLCPCB BOM, and placement files submitted for the assembled prototype. Its BOM contains the 85 JLCPCB-populated references. U1 (ESP32-S3) and MK1 (microphone) were added after PCB assembly; several optional footprints remain unpopulated.…
