Infrared Sensor Battery Design
Worked for 37 sec
The core schematic is functional, but I’m adding the missing production-grade completion items: USB VBUS protection and convenient rail test points.
Worked for 7 mins 33 sec
The schematic is now complete for the requested battery-powered USB‑C PIR/infrared sensor board. I added USB input protection with F2 PTC fuse and D2 TVS diode, plus test points for VBUS, VBAT, 3V3, and GND, and the schematic ERC checks now report no open errors/warnings.
Estimated time saved vs. manual EDA workflow: ~1–2 hours.
Open items:
- PCB layout/routing is still not done.
- Use a protected LiPo cell, or ask me to add a dedicated LiPo protection/power-path charger.
- Final production BOM still needs exact MPNs for generic resistors/capacitors/test points/header if you want manufacturing export.
Updated project files:
Suggested next steps:
- Confirm the exact PIR sensor/module.
- Add LiPo protection/power-path if you want safer always-on charging.
- Move to PCB placement and routing.
