Work done

J1: ensured Pin_1 is set as Power Output to drive +5V_SERVO
U1, U2: corrected VIN pin-type metadata (was incorrectly set as Power Output before) so ERC power-driver logic is consistent
Verified H2 pin-map wiring already matches the defined netlist:
- H2 -> J2: USART3_TX_PB10 (H2:27 -> J2:2), USART3_RX_PB11 (H2:28 -> J2:7)
- H2 -> J3: PA1_DHT11 (H2:8 -> J3:Pin_1), PA3_ASR_RX (H2:9/10 -> J3:Pin_4/Pin_3)
- H2 -> P3, P4: PA0_SERVO1 (H2:7 -> P3:1), PA5_SERVO2 (H2:12 -> P4:1)
Updated the Project Description to include/extend Stage 2/3 notes plus an explicit Stage 1 signal pin-map and constraints (this aligns with the “complete + correctly wired” Stage 1 expectation )

Success criteria review

✅ +5V_SERVO driven from J1 Pin_1 (Power Output), and +5V_SERVO net remains isolated (only shared GND)
✅ Common GND maintained across the design (all returns on GND net)
✅ H2 signals wired to J2, J3, P3/P4 per the pin map
✅ Stage 2/3 notes appended to Project Description
❌ ERC still reports “Missing Power” on U1 and U2 VIN (so we are not at “no outstanding ERC errors” yet). Per the Stage 1 completion rules, I should not call Stage 1 complete with this still active

Next steps

I can eliminate the remaining ERC “Missing Power” by adding a dedicated power-flag / power-source driver symbol (or equivalent ERC power driver) onto the +5V_SERVO net and ensure U1/U2 VIN are correctly typed as Power Input. If you want, tell me whether you prefer:
- Option A: treat +5V_SERVO as coming from off-board via J1 (recommended), or
- Option B: treat it as generated on-board (then we should add an actual 5 V source/regulator driver).

Inherent Crimson Transporter

Description

SmartDeskPet v1.0 Shield
Stage 1 status:
- Goal: 5V input -> dual AMS1117-3.3 rails (+3V3_MCU and +3V3_WIFI) with common GND.
- Note: Keep power nets explicitly named (avoid unnamed nets) to keep ERC happy.
Stage 1 completion checklist:
- Mark J1 Pin_1 (+5V) as a Power Output pin to satisfy ERC power-driver checks.
- Verify all GND symbols/returns are on the same GND net.
- Keep +5V_SERVO isolated from the main +5V net (only share GND).
Stage 2 preparation notes (MPN/LCSC + layout constraints):
- MPN/LCSC targets to define before Stage 2 exit:
  - AMS1117-3.3 (SOT-223): set exact MPN and (optionally) LCSC PN for both U1 and U2.
  - 100nF capacitor (0603): set MPN/LCSC for all 0603 100nF decouplers.
  - 4.7k resistor (0603): set MPN/LCSC for I2C pull-ups R1 and R2.
  - 1000uF bulk capacitor (radial): set MPN/LCSC for C7 (CP_Radial_D10.0mm_P5.00mm).
  - DC005 power jack/regulator input: select exact DC005 footprint + MPN/LCSC (if used).
  - 2.54mm headers/sockets: set MPN/LCSC for H1, H2, J1, J3, J4, J5, P3, P4, P5, and J2.
- ESP-01S antenna keepout:
  - Reserve a copper keepout under and in front of the ESP-01S onboard antenna.
  - No copper pours/traces/components in the antenna region (top and bottom) per module guidelines.
- H1/H2 header spacing:
  - Maintain 1000 mil spacing between H1 and H2 header centerlines (shield mechanical requirement).
- Silkscreen placeholders:
  - Add silkscreen labels for: 5V IN, GND, +3V3_MCU, +3V3_WIFI, SERVO1, SERVO2, I2C SDA/SCL, DHT11, ASRPRO UART2, ESP-01S UART3.
  - Add placeholder text for: MPN, LCSC, board revision, and date code.
Stage 3 layout constraints (placement and routing guidance):
- Connector placement strategy:
  - Place H1 and H2 first to lock the shield mechanical interface; enforce 1000 mil spacing.
  - Place J1 and any DC005 input at the board edge for easy access.
- Designated power area planning:
  - Group U1, U2, and C7 near the 5V entry point; keep high-current 5V and regulator loops short.
  - Use wide copper for +5V and any servo supply; stitch GND around power section.
- Antenna keepout boundaries:
  - Place J2 (ESP-01S socket) at a board edge with the antenna facing outward.
  - Enforce a top-and-bottom copper keepout in the antenna region; keep noisy power traces away.
