These are black and gold blank panels following the Intellijel 1U format. Both sides can be used, one has the Dusty Clouds logo on it.
The panels are made of PCB with matte black solder mask. The exposed copper is coated using the ENIG-RoHS (Nickel and Gold) finish for extra durability and nice golden color.
**Disclaimer | Before you buy** The panels are made of PCB so there will be minor imperfections on the silk screen, or the solder mask, the holes, the cuts etc.. In fact, it’s really rare for a PCB panel not to have imperfections. This has to do with the manufacturing process and the materials that are used.
