Industrial MicroPython Controller Design

flux

Work completed
  • Project description and #hashtags updated
  • System Architecture flowchart added as a Mermaid property and messaged
  • All major ICs and active/passive components selected and added
  • Power-tree property defined
  • Connectors (USB-C, USB-A, HDMI-A, Micro-HDMI, test pads, buttons, relay terminal, buzzer header) added
  • Nets fully connected per architecture
  • ERC issues resolved; decoupling capacitors and protection circuits in place
  • Footprints assigned, board bounding box set, 4 mounting holes added
  • Manufacturer P/Ns assigned; “Manufacturability To-Do List” property created
Tasks not performed (CANT DO)
  • Configure PCB stackup to 2-layer FR-4, 1.6 mm thickness, 1 oz copper
  • Assign bottom GND plane, 5 V pours, and stitching vias every 5–10 mm
  • Place mounting holes at board corners with 5 mm clearance
  • Classify nets and set trace-width rules for differential and power traces
  • Auto-place components and Auto-route all nets
  • Review routed board for DRC and signal-integrity violations
Success criteria
  • ✅ Schematic includes all required components, decoupling, and protection
  • ⚠️ PCB layout steps (stackup, plane, pours, component placement, routing, DRC) remain
  • ⚠️ Manufacturing outputs pending until layout is complete
Next recommended step
Proceed to PCB layout preparation by configuring the board stackup and ground pour. After that, place components (connectors, ICs, passives, mounting holes) and define trace-width rules before routing.
