PCB checklist

• Schematic
  • ERC
  • Components annotate
  • Position and labels of all controls match the schematic
  • Position and labels of all IO match the schematic
  • Indication match the IO and controls
  • All inputs more than 10k impedance
  • All outputs has 100 Ohm protection
  • Check BOM
    • remove pogopin, diodes, opamps
  • Backlight
• PCB
  • DRC
  • Check silkscreen
  • Check board outline
  • Name of the module, logo
  • link to site
  • version of the module
  • ±12, +5, GND marks
  • Sensitive circuits (high impedance, high frequency, opamp/power amp feedback)
  • Inverted soldermask under the silkscreen on indication windows
