Industrial-Grade Hardware
Everything you need to transform any "dumb" motor into an intelligent, connected asset. From mounting brackets to sensor electronics.
Mounting Hardware
Clean, functional design built to fit NEMA 56C frame motors. Compatible with our sensor kits right out of the box.
- • 1/4" steel motor mounting brackets
- • Designed for NEMA 56C frame motors
- • Optional handle for mobile deployments
- • Torque sensor ready (drill/weld your own mount)
Sensors & Controller
The brains of the operation. Industrial-grade sensors and ESP32-S3 controller with Edge AI capabilities.
- • Smart Sense Controller (ESP32-S3)
- • Vibration, Current, Audio, Temp, RPM, Torque sensors
- • LoRaWAN + Wi-Fi + BLE connectivity
- • 8V–200V power input with failover
Core Processing & Memory
ESP32-S3-WROOM-1-N8R8
- Dual-Core 240MHz — Real-time sensor processing
- 8MB Flash — Firmware and model storage
- 8MB Octal PSRAM — High-frequency data buffering for FFT analysis
- Native Wi-Fi & BLE — Wireless connectivity built-in
MicroSD Storage
Onboard MicroSD slot for "Black Box" recording. Continuously logs raw sensor data for post-failure forensic analysis.
SPI/SDMMC interface • Bottom-side placement for compact design
Sensor Suite
Vibration
IIM-42352
TDK InvenSense 3-axis Smart Industrial Accelerometer. Mounted on isolated "sensor island" for precision readings.
Current
ACS723LLCTR-20AB-T
±20A bidirectional Hall-effect sensor. Analog output routed to high-speed ADC.
Audio
I2S MEMS Mic
Digital microphone for acoustic fault detection—catches bearing squeal before catastrophic failure.
Temperature
NTC Thermistor
External temperature probe for motor winding or bearing temperature. Early warning for overheating conditions.
RPM
Optical Tachometer
Non-contact optical sensor for shaft speed measurement. Essential for efficiency calculations and slip detection.
Torque
NAU7802SGI
24-bit ADC for load cell amplification. Measure actual mechanical output for true efficiency.
Communications
LoRaWAN
RAK3172 module (STM32WLE5) with u.FL antenna connector. Miles of range, years of battery life.
Wi-Fi / BLE
Native ESP32-S3 connectivity. High-speed local dashboard + mobile app configuration.
Interfaces
Power Management
Wide Input Range
8V–200V DC input via wide-input buck converter (MP9486). Works with virtually any DC motor power supply.
Automatic Failover
When motor voltage drops to 0V, device seamlessly switches to USB-C or LiPo backup to send "Motor Off" status.
Status LED
WS2812B addressable RGB LED. At-a-glance system status— green pulse for healthy, red flash for alert.
Open Source Design
RotorIQ hardware is fully open source. Access KiCad 8 project files, Gerbers, BOM with LCSC part numbers, and 3D STEP models.
