| Step | Action | Detail / Tips |
|---|---|---|
| 1. Define the Board Outline | Create a board outline of 2 cm x 2 cm | Ensure that the dimensions are accurately set within the PCB editor to reserve enough area for all components and routing. |
| 2. Reserve the Controller Zone | Allocate an area for the ESP32-WROOM-32 placement | Place the ESP32 in a zone that does not conflict with other design elements (especially the LED grid and interconnect connectors). |
| 3. Design the LED Cube Grid | Position and define a uniform grid for mounting LED cubes, with each mounting pad sized to occupy 5x5 mm | Arrange the LED pads in a consistent grid pattern across the available area without overlapping the reserved ESP32 area or connector zones. |
| 4. Place Interconnect Connectors | Add board-edge connectors for power and signal sharing | Select connector footprints (like multi-pin headers) and place them along one or more board edges. Ensure they do not infringe on the LED grid or ESP32 zone. |
| 5. Route Interconnect Traces | Define signal and power routing paths that join the connectors, controller, and any peripheral decoupling elements | While routing, keep traces clear of the LED grid area. Use appropriate clearances to maintain signal integrity and avoid congestion. |
| 6. Verify and Adjust Layout | Run Design Rule Checks (DRC) within the PCB editor | Ensure all spacing, clearances, and connectivity meet the required design constraints. Adjust as necessary based on DRC feedback. |
