WearableAI

Personal wearable AI assistant built from scratch for the Arduino Nano RP2040 Connect.

A complete firmware + host-tools + mobile-server + desktop-server codebase for a modular, self-healing, self-improving wearable AI assistant. Every layer — from HAL interfaces to wire protocol to model format — is designed to outlive any single component.

• arp-2040/ — RP2040 firmware (FreeRTOS, C++17), host tools, emulators, model compilers
• arduino-mcp-toolkit/ — MCP server with 35 tools for Arduino control, TinyML, mesh, OTA
• arduino-dashboard/ — FastAPI + WebSocket dashboard with serial/BLE/Wi-Fi transports
• docs/ — Design blueprint, HAL spec, protocol spec, build plans

• Arduino Nano RP2040 Connect — RP2040 dual-core 133 MHz + NINA-W102 Wi-Fi/Bluetooth
• Onboard: LSM6DSOX IMU, MP34DT06J MEMS mic, ATECC608A crypto, 16 MB QSPI flash

• Atomic firmware upgrades with rollback
• Hot model reload without downtime
• Self-modifying code via control graphs and bytecode interpreter
• TinyML training and on-device inference
• BLE + Wi-Fi hybrid mesh networking
• ATECC608A hardware security
