2024-03-31 (Su) RADARBadge SAO accessory

DEFCON badges are a tradition, but Shitty-Add-On (SAO) PCBs are another fun way to make boards with less commitment. I did not add any SAO ports to my badge, but I wanted a way to attach one to spin. I looked up the required hardware and connections for the SAO and placed a 2x2 female header into a PCB layout. I put one battery holder, but it seemed unbalanced, so I added a second and wired them in parallel. The back has a message that you can use one or two batteries.
