+
+### 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](/img/kit/assembly_pic47.jpg)
+
+
+> **Connect the 4-wire cable to the J9 header**
+
+!!! note
+    It doesn't matter if the color of your cable won't match the one you see in the picture, just plug in any order.
+
+![Kit Assembly](/img/kit/assembly_pic48.jpg)
+
+![Kit Assembly](/img/kit/assembly_pic49.jpg)
+
+
+> **Assemble the OLED display to the front panel. Respect orientation.**
+
+!!! warning
+    Don't tighten too much the nuts, you don't want the OLED circuit board to bend or break.

+
+### 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.
