Understood — you want the full electronics schematic/PCB plan.
I’m currently blocked from building it directly in the project because execution is unavailable in this session, but here’s the concrete plan I would implement next:
- Core controller: ESP32-S3 module for Wi-Fi/Bluetooth plus camera interface.
- Camera: small visible OV2640-class module at the top edge.
- UI: calculator keypad matrix, separate physical capture button, standard display.
- Privacy: no auto-capture, no background recording, indicator LED tied to camera power/enable, confirmation required before wireless send.
- Power: 1-cell Li-ion battery, USB-C charging, battery protection, regulated 3.3 V rail.
- Connectivity: BLE for pairing/control, Wi‑Fi for image transfer to phone/computer app.
- PCB approach: calculator-style rectangular board, top-edge camera, front-facing keypad/display, USB-C on bottom or side edge, RF keepout around antenna.
Recommended functional blocks:
- ESP32-S3 module
- Camera connector/module
- Display interface
- Keypad matrix
- Capture button + camera LED
- USB-C charging + battery path
- 3.3 V regulation + decoupling
- Programming/debug header or USB data path
What remains to be done:
- Select exact parts and footprints
- Create the schematic per datasheets
- Run ERC/review and fix issues
- Then proceed to layout after your confirmation
If you want to continue manually or in a later session, I’d start with this exact spec:
- 3.7 V Li-ion battery
- USB-C rechargeable
- ESP32-S3-WROOM module
- OV2640 camera
- 2.4" to 2.8" display
- 4x5 or 5x5 keypad matrix
- one capture button
- one green camera-active LED
Ready for me to turn that into a detailed schematic netlist and BOM in the next session.
