Tools Needed
- Wire Cutters / Pliers
- Soldering Iron + Solder

Parts Needed
Pre-Built OpenDoorSim Board (For Wiring Reference)
Either from the official kit or self-manufactured.
LAB Kit Screen and Encoder Parts
The kit comes with all parts needed for the following steps.If you want to double check you have the parts, or don’t have a kit, or are self-ordering, check out the Screen and Encoder’s Bill of Materials.
Build Guide
STEP ONE: SCREEN
Solder 4-PIN JST wire harness to OLED Screen
Solder the 4 bare end wires of the JST harness into the OLED screen, following the connection table below. Wires should go in from the underside of the screen.



STEP TWO: ENCODER
Remove Pin Header From Encoder
If your encoder includes pin headers, they must be removed.First, bend the encoder pins straight(ish) so they are easier to remove, using pliers or cutters of your choice.Next, heat each pin with a soldering iron, and use pliers / cutters to gently grip, wiggle, and pull them out one by one.






After removing, some solder may remain, but the pins and plastic pin header should be gone to make room for the wires.

Solder 5-PIN JST wire harness to Encoder
Solder the 5 bare end wires of the JST harness into the encoder, following the connection table below. Wires should go in from the underside of the encoder.
