Project Overview
Production-intent 2-layer motherboard for a smart face-recognition door lock. Status: Review.
Intended Use
Indoor commercial access-control prototype/validation build controlling a 12 V drop-bolt lock and interfacing to an external 3D biometric module and HLK-LD2410C presence sensor.
What the Device Should Do
- Accept a protected 12 V DC supply.
- Run an ESP32-S3-WROOM-1-N16R8 with Wi-Fi/BLE and native USB programming.
- Power-gate a 5 V biometric camera module and communicate over UART.
- Monitor a 24 GHz presence sensor and support low-power wake.
- Switch a 12 V inductive lock load with fail-safe default-off control.
- Provide audible confirmation.
- ESP32-S3 module with 16 MB flash and 8 MB PSRAM.
The validated specification is saved and the schematic build is underway. The corrected design uses valid ESP32-S3 GPIOs, protected/self-powered USB-C, a higher-capacity power tree, and a fail-off lock driver rather than the ineffective pseudo-isolated stage.

"ESP32 Door Lock Schematic" completed.
Thought for 5 sec
The project is now named Smart Face Recognition Door Lock, and I created the validated Project Specification. The schematic build added 71 components and 45 nets, including the ESP32-S3, AP63301 power conversion, USB-C/ESD circuitry, camera load switching and level translation, radar interface, relay/lock driver, buzzer driver, connectors, and mounting holes.
Open items
- I could not perform the independent schematic/ERC verification after the build.
- The 70 × 48 mm board outline, placement, antenna keepout, routing, and final DRC remain unfinished.
- Exact camera and lock current requirements still need confirmation before production release.
Next steps
- Independently inspect and correct the completed schematic.
- Pause for schematic approval.
- Set up and place the two-layer PCB.
- Route and run final DRC/manufacturing checks.
Execution stopped because your ACUs ran out.
