Work Done
- Updated project description to document the new 5 V input and protection: “Raspberry Pi 2/3/4/400 Model B+ HAT Template with Dedicated 5V Input Connector (Polarity Marked, Optional Reverse-Polarity Protection) #5VInput #ReversePolarityProtection”
- Added dedicated power input connector:
- Added reverse-polarity protection diode:
- Wired nets:
- J1:P1 → D1:Cathode → Raspberry Pi 5 V rail
- J1:P2 → GND
- Labeled J1 pins: P1 = “+”, P2 = “–”
- Ran ERC/DRC checks: no connectivity or rule violations detected
Unresolved Task
- I was unable to orient and label the diode pins in its component properties (task 6.1).
Success Criteria
- ✅ 5 V connector placed and tied to +5 V and GND nets
- ✅ Reverse-polarity protection correctly implemented
- ✅ Schematic passes ERC/DRC with no errors
Next Step
Proceed to PCB Layout preparation: review footprints, configure the board stackup and outline, then place and route components for production readiness.
