Additionally, we need two 3.6 V Zener diodes for the data lines, Z1 and Z2. Here, you have to pay attention to their orientation. The (black) line on the diode is the same as the single line on the symbol (as opposed to the triangle) that is printed onto the PCB. You can see that in the figure on the left. | |||

A full schematic of the PCB can be downloaded here: Datei:Cube.pdf.
USB Resistors
First we solder R10, R11, R13, Z1 and Z2. As all resistors we are using in this project, their orientation is not relevant. You can see the resistor values in the schematic or in the table below, together with the color code marking:
| Name | Value | Color Code |
|---|---|---|
| R10 | 68 Ohm | 
|
| R11 | 68 Ohm |
|
| R13 | 1500 Ohm |
