Add verified C381116 as J4 and connect it only to VIN_RAW/GND

Place J4 without moving existing parts and add both requested silkscreen notes

Verify 36/27 counts, exact net diff, J1 unchanged, and ERC

I found a scope violation during reconciliation: adding/placing J4 shifted many existing PCB components (including J1), despite the executor’s report. I’m preserving the current state in a named snapshot, then I’ll restore pre-J4 placement while retaining J4, its two intended net additions, and both silkscreen notes.

RGBW Driver - Pre Placement Restoration Snapshot 2026-09-03
Welcome to your new project. Imagine what you can build here.

Reconciliation found an unintended PCB placement shift affecting many existing components, including J1. I created the required snapshot: RGBW Driver - Pre Placement Restoration Snapshot 2026-09-03.
Current project state:
  • J4 and both silkscreen notes are present.
  • J4 pin 1 added to VIN_RAW; pin 2 added to GND; pin 3 is intentionally NC.
  • Schematic has 36 components and 27 nets.
  • ERC still has the three accepted +5V_DRV missing-power-driver errors.
  • Existing PCB placements still need restoration to their pre-J4 coordinates; no restoration mutations were made.
Execution stopped because your ACUs ran out.

Scope status
  • Component population: Completed — exactly 35 components.
  • Logical connectivity: Completed — exactly 27 named nets.
  • PCB placement/routing/Auto-Layout: Unattempted as required; no PCB tools were used.
  • ERC: Completed once after wiring; findings are reproduced exactly below and were not fixed.
  • Schematic presentation: Components were assigned to functional groups and placed by the schematic insertion flow. No PCB placement occurred.

Connectivity confirmations
  • U1 pin mapping used: FB=1, EN=2, VIN=3, GND=4, SW=5, BST=6.
  • U1.FB directly joins +5V, sharing the net with L1.2, C2A.1, C2B.1, FB1.1 and J3.2. There is no feedback divider.
  • U1.EN directly joins VIN, sharing the net with U1.VIN.
  • C1 and C8 are each rated 50 V, meeting C1 ≥50 V and C8 ≥35 V.
  • R6-R10 each connect its corresponding driver-input net to GND.
  • U2/U3/U4 ENA and ENB are all intentionally open/no-connect.
  • U4.INB is tied to GND. U4.OUTB is intentionally unconnected/no-connect.
  • D1 polarity is cathode to VIN and anode to GND for positive-input transient protection.
Negative checks
  • J3 module signals connected only for GPIO3, GPIO4, GPIO5, GPIO6 and GPIO7, plus 5V and GND.
  • GPIO0, GPIO1, GPIO2, GPIO8, GPIO9, GPIO10, GPIO20, GPIO21 and 3V3 are intentional no-connects.
  • No MOSFET gate is directly connected to a GPIO. Every gate path passes through its UCC27524 output and a 33 Ω resistor.
  • J3 3V3 (pin 6 under the specified socket mapping) is unconnected.
