Made a few simple programming jigs for the HackerHotel2020 badge. It hasn't got a mounted USB or other port, so pogo-pins are needed for fast and simple connections.

Export Copper layer from Kicad as SVG, use Inkscape strip it down to board outline and holes, use holes as guides on where to place circles in Inkscape. Add some more stuff you want cut or engraved and you're done.

4 layers of hardboard, lasercut. It's the same drawing, just different layers each time. Stackup as follows:

  • Top plate has engraving, batterybox cutout, holes for pogos, and holes for the M3 screw heads.
  • Second plate has batterybox cutout, holes for pogos and holes for M3 screws.
  • Third plate has holes for pogos and holes for M3 screws and zipties.
  • Bottom plate has no holes for the pogo pins, just holes for the M3 screws 30mm and the zipties.

Pogopins are inserted, then wires soldered on. They stay in place because the holes are just small enough to have a nice press-fit. Lots of M3 nuts are used in the process of making the stack. Top two plates are glued together, bottom two are held together by additional M3 nuts.

Colorscheme (untested, do not use unless verified!):

  • Brown - VPP
  • Red - IN
  • Orange - OUT
  • Yellow - GND


  • Green - RX
  • Blue - TX
  • Purple - SCL
  • Grey - SDA
  • White - GND
  • Black - 3.3v
