Assembly quick overview

Step 1 - Preparing acrylic plates

Kit Assembly

Each acrylics plate is recovered with a protective layer on both sides. Peel the protective layers slowly and insure no left-over sticks to the plate.

Kit Assembly

Because of the die-cut intricacy of the front panel, the laser cut process might have left the scrap pieces in place. You will have to use a a tool (e.g a pen or a flat screwdriver) to push out the scrap pieces. You might have to do the same for some of the screw holes on the other plates.

Important

This task requires the most patience. Don't rush it or you risk to damage it.

Optional Assembly Step

OLED Display - Part A

Prepare the following items.

  • OLED display
  • 4-wire dupont cable (Length : 30cm)
  • 4x clear plastic screws + nuts
  • Front Panel

Kit Assembly

Connect the 4-wire cable to the J9 header

Note

The color of your jumper cable is most likely different than the one you see in these pictures. The purpose of the different colors is just to help you check your wiring is correct. Plug in any order.

OLED Display - Part B

Connect the 4-wire cable to the OLED screen.

Important

The PIN order is different between the J9 header and the OLED header. You will need to connect each cable to match the same PIN name between the OLED header and the J9 header (GND to GND, VCC to VCC, SDA to SDA, etc...). See below the J9 and Display header pinouts.
