Queen City Con 0x4 Badge

nRF52840 LoRa mesh badge in standard, supporter-with-keyboard, and DIY kit versions

The electronic badge family of Queen City Con 0x4, Cincinnati, November 13-15, 2026. The organizers' schematic export covers a triangular standard badge, a supporter badge with a CardKB-style keyboard, and a DIY kit badge, all built around an nRF52840 and an Ai-Thinker Ra-01SH SX1262 LoRa module, with connections for an I2C OLED, a keyboard, and GPS, plus a buzzer and indicator LEDs. The firmware guide notes that fitted parts differ from badge to badge. A third-party design document says the badge ships with Meshtastic, while the Offband MeshCore fork, which the conference organization forked on November 8, 2026, publishes a dedicated QCC Badge companion firmware.
