Add-on dossier
A linkable lifecycle record for hardware expansions, app ecosystems, firmware upgrades, cases, radio parts, and post-event badge experiments.
The repository preserves user-app directories for games, screensavers, spectrum analysis, text adventure, air-quality, hardware-monitor, app-manager, and other MicroPython examples.
Badge context
Hackaday reveal source for the Communicator Badge name, LoRa mesh-chat concept, ESP32-S3, keyboard, LCD, SX1262 radio, LiPo charging, LVGL MicroPython, team credits, and after-event hacking intent.
Hackaday source for front-panel customization, two-PCB stack-up, front-board mechanical role, M3 hardware notes, and STEP/DXF/SVG model path.
Raw BOM source listing ESP32-S3-WROOM-1, Wio-SX1262-N, TCA8418, USB-C, LiPo charging, SAO connector, keyboard, LED, and related passive/connector components.
Hackaday event source for October 31-November 2, 2025 dates and Pasadena, California context.
Firmware source for MicroPython, LVGL, ucryptography, asyncio, LoRa network stack, protocol ports, TTL relay behavior, RF channel notes, ImHex packet pattern, app lifecycle, and development workflow.
Raw firmware source for keyboard I2C, LCD pins, LoRa SPI, radio control pins, SAO I2C, SAO GPIO, and debug LED assignments.
