The kind of project you understand immediately just by holding it in your hands.\n- **Context** : Radiocommunication student project, two-person team.\n\n## Documentation\n\nThe documentation is quite detailed, so each part has its own page instead of having it all here.\n\n### Find your happiness:\n- ⚙️ [Hardware Architecture](./docs/architecture.md): Functional synoptic diagram and component details\n- 🛠️ [Firmware](./docs/firmware.md): ESP-IDF, libraries, code architecture\n- 📡 [Radio Parameters](./docs/radio.md): How we use LoRa\n- 🎙️ [Audio Processing](./docs/audio.md): A voice's journey through the system\n- 👤 [Human-Machine Interface](./docs/hmi.md): How does it works for the user\n- 🔋 [Power Supply Circuit](./docs/power.md): Power management and energy consumption\n- 🔌 [Electronics](./docs/pcb.md): Prototyping, KiCad, RF design, routing rules, our conception choices\n- 📐 [CAO](./docs/cao.md): Our vision of an enclosure for this device\n\n## Repository Structure \n```\n├── hardware/        # KiCad schematics, PCB\n├── firmware/        # ESP-IDF code\n├── docs/            # Documentation, conception notes\n├── media/           # Images, schematics and illustrations\n└── case/            # 3D models\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmilovanpms%2Ftalk-e","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmilovanpms%2Ftalk-e","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmilovanpms%2Ftalk-e/lists"}
