Notes on prototyping circuit boards: breadboards, perfboards, and beyond

Breadboards

Perfboards

  • 1 (yellow): ground
  • 2 (white): GPIO 19 (board pin #35) input to Raspberry Pi
  • 3 (green): power

Custom PCB Manufacturing

  • Eagle PCB templates
  • KiCad
  • $5.000/ea (1x), Schmartboard 5.080x5.080cm, 0.1" + 0.050", 2-side
  • $1.400/ea (10x), Dirtypcbs 5x5cm, 2-side, custom design
