PCB Design — A Hobbyist’s Perspective

From Breadboard to PCB

  1. Drawing the schematic — this often includes drawing custom symbols and footprints for the required parts
  2. Laying out the design for physical production on a PCB
  3. Creating a bill of materials (BOM)
  4. Having the PCB manufactured
  5. Assembling the board or having it assembled
