Edge AI Firmware
The "Small Motor Model" runs entirely on-device. No cloud required for real-time fault detection, efficiency calculation, and predictive insights.
The Small Motor Model
Virtual Dyno
Real-time efficiency calculation without external test equipment.
- ▸Efficiency: Powerin / Powerout
- ▸Torque Ripple: Detect mechanical issues
- ▸Load Profiling: Understand duty cycles
Machine Doctor
Edge AI inference engine that diagnoses problems before they become failures.
- ▸4kHz sampling of vibration + audio
- ▸FFT analysis buffered in PSRAM
- ▸Fault flags: Bearing, Imbalance, Alignment
Black Box Recorder
Continuous data logging for post-failure forensics and compliance.
- ▸MicroSD logging of raw sensor data
- ▸Timestamped events for incident analysis
- ▸Exportable data for external tools

Data Strategy
📶 Wi-Fi (Local)
High-bandwidth, real-time data for local monitoring.
- • WebSocket streaming for live graphs
- • React dashboard hosted on ESP32-S3
- • Full sensor resolution (4kHz)
- • Instant response for troubleshooting
📡 LoRaWAN (Remote)
Low-bandwidth, long-range for fleet monitoring.
- • Heartbeat every hour (configurable)
- • Event triggers: "Stall Detected", "Temp Alert"
- • Works without Wi-Fi infrastructure
- • Miles of range, years of battery
Plug-and-Play Expansion
Connect any Qwiic/Stemma QT sensor to the expansion port. The firmware automatically scans the I2C bus, identifies the device (OLED screen, temperature sensor, etc.), and integrates it into the dashboard.
Open Source Firmware
The entire firmware stack is open source. Clone the repo, customize the model, and deploy to your fleet.
