Kurokesu SCF4 multi-axis stepper motor controller System On Module (SOM) targets applications where time to market, reliability and small footprint is important. Main control MCU is ST Cortex STM32F103 powerful enough either to run standard or run dedicated standalone firmware. The motor front end is based on ON Semiconductor new and highly specialized chipset LC898201.

Some standalone use examples:

React to lidar distance sensor and adjust focus/zoom accordingly
Switch day/night filter by measuring ambient light intensity (with dedicated analog or digital sensor)
Take R/C inputs and control Remote-controlled drone or vehicle lens
Switch / reconfigure lens by single GPIO input (for example: reconfigure lens for wide/near operation by toggling GPIO pin)
And much more...

Managed mode (default) target applications worth mentioning:

Computer vision and analysis applications
Scientiffic applications
Neural network image processing and recognition applications
Transport systems (ITS)
Universal Pan/Tilt/Zoom and/or Focus/Zoom/Iris/+ driver
Toll systems
Trafic or segmental speed measurement
ROV/Drone lens control unit
Face recognition applications
Long term time-lapse cameras
Distant camera installations that may require reconfiguring optical train remotely
And much more...
