So... no schematic, no BOM, and the markings on the PCB have little pictures. LOLZ! Don't fret, this is where the fun comes in. It was mentioned in the earlier log, but essentially you need to crack a cipher. This can be done quantitatively (i.e. using frequency analysis) or qualitatively (i.e. seeing how the images relate to one another, putting them in the right order, and understanding how they map to the alphabet). To do this, you need SAMPLES and a good shot of the badge. See below and get crackin! We highly recommend you collaborate with others on site at the CPV or online in our Slack (OR BOTH!)
These may also lead you to understand how the front face castellated PCB's get properly soldered on...
