Below is a summary of the key steps for PCB layout—please refer to the Start to Finish Tutorial - PCB Layout for the complete guidance:
-
Component Placement:
- Switch to the PCB layout tab.
- Position major components (like the ESP32-WROOM-32 and SX1278) as anchors.
- Group related components (sensors, regulators, decoupling capacitors) to optimize signal paths and reduce trace lengths.
-
Trace Routing:
- Route traces according to your established nets for power, signal, and ground.
- Follow design best practices from the tutorial, ensuring controlled impedance, minimal via usage, and avoiding crossing sensitive signal lines.
- Run your design rule checks (DRC) to catch any routing issues like trace spacing, copper islands, or unconnected nets.
-
Manufacturing Readiness:
- Verify the board stackup and layer assignments.
- Check for proper clearance between pads and copper pours.
- Use the export tools to generate manufacturing outputs (Gerber files, netlists, BOM, etc.).
Following these steps while referring to the tutorial ensures your design meets both electrical performance and manufacturability requirements.
