New PCB design for TinyTimer

  • replaced switch with pin-header and shunt (jumper).  This is more cost effective and avoids the switch footprint issues.
  • rearranged the crystal and capacitors to ensure no routing errors as on the previous PCB.
  • added a ground plane.
  • located all controlled circuit traces to top of PCB.
  • changed axial capacitor out for more cost effective equivalent capacitor with higher voltage rating (600v old component, 1000v new component).
  • Adjusted component layout to produce traces with fewer vias.
  • Adjusted holes in PCB for mounting purposes.
