Secondary first-hand post-camp source: a community firmware author describes the board as handed out at RomHack Camp, says every detail was checked on a real badge, and adds the Qwiic/STEMMA QT port, the PCB-coil NFC antenna, the Traboda brand on the PCB, and an AW9523B burst-read quirk. It does not give a badge count.
