ESP32-S3 Meshtastic LoRa badge with Type-B fallback
The ROOTCON 20 con-goers guide documented a September 2026 badge distribution model: electronic badges distributed first-come during on-site check-in while supplies last, with a simpler Type-B non-electronic badge fallback. After the September 23-25 event, ROOTCON's official media server published a post-event ROOTCON 20 drop on September 28, 2026, including rc20-human-fw.bin, a compiled ESP32-S3 firmware image that identifies itself as the ROOTCON 20 Badge and runs a Meshtastic LoRa mesh stack on an SX1262 radio with an SSD1315 OLED, four WS2812B LEDs, and Tetris and Breakout games.
