Compatible Printed Case that ours is based on:

Wiring the Module

  • Included is a length of 2 conductor wire.There is a red and black wire inside the single wire.
  • Carefully strip the outer wire covering to expose the 2 wires inside
    • If you do not have wire strippers you can use a razor or a sharp knife. Don’t press too hard, just enough to cut the outer wire cover.
  • Strip the Red and black wires at each end
    • Cut to the length you need before stripping if the included wire is longer than you need.
  • Insert the red wire into the blue terminal on the side labeled “IN+”, tighten the screw terminal screw for that side down.
    • Do NOT over tighten. Just snug it so that the wire does not come out of the terminal
  • Insert the black wire into the blue terminal on the side labeled “IN-“, tighten the screw terminal screw for that side down.
    • Do NOT over tighten. Just snug it so that the wire does not come out of the terminal
  • Connect the other end to your printer power supply. Make sure to connect to the DC side (Usually marked with V+ and V-). Do NOT connect to terminals labeled L, N, and G (this may have an icon instead of G with lines)
    • The red wire connects to V+ on your power supply.
    • The black wire connectes to V- on your power supply.
  • Verify that your red wire is going to IN+ on the Pi Direct Wire Power Board and the other end goes to V+ on your power supply
  • Verify that your black wire is going to IN- on the Pi Direct Wire Power Board and the other end goes to V- on your power supply
  • Connect a MicroUSB cable from the Pi Direct Wire Power Board USB port to your Pi MicroUSB Port
  • Power on your printer. The Pi will then power up from the direct wire board.
    • Tidy up your wires so that it all looks nice and nothing is getting pulled on
  • You’re done! Happy Printing!

Powering your Pi from the Module

If you get the Pi Direct Wire Power adapter as part of the kit you will need to supply a MicroUSB cable. When selecting a USB cable use the shortest one possible and not a cheap one. Cheap MicroUSB cables cannot handle the current that the Pi needs to run and if your cable is too low quality the red LED on the Pi (look inside the case near the MicroUSB plug) is off then the USB cable cannot handle the 2.5A minimum that the Pi needs to run.
