Add-on dossier
A linkable lifecycle record for hardware expansions, app ecosystems, firmware upgrades, cases, radio parts, and post-event badge experiments.
The firmware tree preserves an AudioWAV sketch with USB mass-storage and PWM audio behavior plus an EdgeImpulse note linking audio-classification tutorial material.
Badge context
README source for RP2040, USB, LEDs, microphone, buzzer or speaker, 115200-baud serial startup, help command, Arduino Mbed path, EdgeImpulse mention, CDMX context, Electronic Cats design credit, and hardware-license statement.
Project wiki linked from the README as the Arduino programming path for the BugCON 2022 badge.
Arduino/RP2040 audio example source with USB mass storage, PWM audio output, 115200 serial setup, and audio amplifier enable path.
Firmware tree preserving AudioWAV, Blink_Bug, the WAV asset, and an EdgeImpulse audio-classification note.
KiCad PCB source file for the physical board layout preserved in the repository hardware tree.
KiCad schematic source backing RP2040, SPH0641LM4H microphone, PAM8302AAD audio amplifier, W25Q16JV flash, MCP1700 regulator, micro-USB, battery cell, buzzer, LEDs, BOOT jumper, and RESET switch claims.
Hardware source tree with KiCad schematic, PCB, project, footprint, and library table material for the RP2040 badge.
Public Electronic Cats repository whose metadata identifies a BugCON 2022 CDMX electronic badge and whose tree preserves README, hardware, firmware, and wiki material.
