This is a resistor decade board and tray to hang it on. The resistance value is selected with the jumpers.

Print flat on the print bed.

The PCB is attached with four 3mm screws.

PCB Features

  • Resistor values from 0 - 9,999,999 ± 1% 
    • Tighter tolerances possible but components cost more
  • Easy to build with commonly available components
    • Designs using 1206 SMT or through hole components available
  • Open source hardware

I included the PCB files for Eagle. Autodesk Fusion 360 includes PCB design and can use Eagle files, I still use standalone Eagle. You can have the PCBs made by a facility like JLCPCB, PCBWay, OSHPark or Digikey DKRed for a couple bucks.

The main files for this are on my Github.
