Tripel - 60% keyboard PCB

Tripel is a 15x4+1x5 key ortholinear keyboard PCB.

The goal of this project is to build a pro-micro powered ortholinear PCB that fits in a standard 60% tray mount case but built from sub-100x100mm PCB boards.

PCB render

  • Designed to be easy to build with minimal soldering experience.
  • Built from 3 of the same PCB.
  • 7u spacebar bottom row.

Bill of Materials (BOM)

  • 3 PCBs.
  • A suitable 60% ortholinear keyboard plate (eg. XD75 plate).
  • 65 MX compatible switches.
  • 65 1n4148 diodes.
  • Pro Micro controller (or compatible alternative).
  • 7u PCB mount stabilizer.
  • Through-hole USB mini or micro connector.
  • USB cable for Pro Micro.

Ordering PCBs

PCBs can be manufactuered by a variety of online PCB fabricators. You can use PCBShopper to search for the best price. Many manufacturers have special rates for prototype boards under 100x100mm in size.

PCBs

The zip file in the gerber directory contains the gerber files your fabricator will need to make the PCB tripel.zip PCB.

When uploading the gerber zip files, use the default PCB settings.

Construction

  • You will need 3 PCBs.
  • Solder the diodes onto each PCB.
    • You can place them on either side, but remember that the right most PCB will be flipped.
    • The end of the diode with black band goes in the square hole.
  • Solder on the Pro Micro headers onto the underside of the middle PCB.
    • Do not solder on the Pro Micro yet.
    • Instead of using the Pro Micro headers, you can use the trimmed diode wires instead.
  • Solder on the USB connector.
  • Insert the switches into the plate.
  • Put the stabilizer together and fit it into the left and right PCBs.
    • If you forget the stabilizer you will need to unsolder all of the switches so as to fit it.
    • Don't forget to trim and lube your stabilizer before fitting if you want to.
  • Place the PCBs onto the switches:
    • The PCBs should be placed the way around as indicated by the soldermask.
    • Insert all the switches and ensure that the pins of each switch are correctly coming through the board and are not bent under the PCB.
  • Solder all the switch pins.
  • Solder the solder bridges between the PCBs:
    • Solder both of the 3 pad and 8 pad bridges on the back of the PCBs.
    • Bridges on the front of the PCB are no longer accessable due to the plate and do not need to be soldered.
  • Solder on the Pro Micro:
    • Ensure that you have it the correct way around, the chip side should be face down towards the PCB with the USB port to the right.
    • You might want to remove the plastic from the header pins so that the Pro Micro can be mounted as close to the PCB as possible.
    • Use electrical tape underneath the Pro Micro if you think shorting against the switch pins could be an issue.
  • Cut your USB cable to length and solder the wires to the pins for the USB connector.
  • Flash the Pro Micro with the firmware, see the QMK documentation on how to build and flash the firmware.
You can’t perform that action at this time.
