- OLED module (4-pin header)
- Control board (3-pin header)
This cable allows communication with the OLED and controls the run and bootload modes on the control board.
Assemble the 3-heads wire as depicted in the image. Color and order matters! Your assembled wire should look exactly like the image indicated.
After assembling the wires, do not plug them in yet.
Now, let’s move on to the wiring section.
