Here’s a summary of what was accomplished:
Work completed
  • Project description updated to “Minimal ESP32-S3 USB-C Powered Blink-LED Development Board with Onboard 3.3 V LDO.”
  • System Architecture property added with the mermaid block-flow diagram.
  • Project properties set:
    • Power Input Option = “USB-C only”
    • ESP32 Module = “ESP32-S3-WROOM-1”
    • LED Configuration = “Green LED on GPIO2”
  • Major ICs placed:
    • J1 USB-C connector (U262-161N-4BVC11)
    • U1 TPS76933DBVT 3.3 V LDO
    • U2 ESP32-S3-WROOM-1 module
  • Passive and reset components added:
  • All nets routed:
    • USB-C 5 V ➔ LDO input & input caps
    • LDO output ➔ 3.3 V rail & output caps
    • GND tied across all components
    • EN/BOOT pull-ups and buttons wired
    • USB_DP/USB_DM to ESP32 programming pins
    • GPIO2 ➔ R3 ➔ D6 ➔ GND
  • ERC issues addressed (added decoupling caps and pull-ups) and BOM enriched with part numbers.
Unresolved tasks None — all plan items are complete.
Success criteria review
  • ✅ USB-C 5 V input regulated to 3.3 V with proper decoupling
  • ✅ EN/BOOT strapping and reset pushbuttons functional for programming
  • ✅ Status LED circuit on GPIO2 with series resistor
  • ✅ ERC and BOM checks completed
Next recommended step Prepare for PCB layout: review footprints, configure the stackup, and select a board mounting solution so we can place and auto-route components.
