January, 2023: Rotary microstage delivers smallest system size, fastest integration for precision embedded motion in smaller, more powerful instruments


The new M3-RS-U2-4.5-360 Rotary Smart Stage brings M3 Smart Stage advantages – high positioning resolution, smallest size, low power, fastest integration – to instruments needing precision embedded motion at lower cost for high-volume production.


With the built-in controller, the M3 Smart Stage simplifies the task of embedding high-precision rotary motion into scientific and industrial instruments. It provides point-to-point angular positioning with closed-loop resolution better than 0.022 degrees and bandwidth of ~100 Hz.


Applications include point-to-point beam steering and optical tuning in imaging systems, point-of-care and clinical instruments, next-gen sequencing (NGS) instruments, industrial measurement and spectroscopy instruments, laser printing and engraving systems, and more.



  • Motion Range: 360 deg continuous rotation
  • Speed: >1,000 deg/sec (point-to-point positioning bandwidth ~100 Hz)
  • Payload Mass: 3 g (mounted to rotating shaft)
  • Resolution: ~0.022 deg with absolute encoding
  • Dimensions: 11.75 x 21.9 x 16 mm – including controller
  • Voltage/Power: 3.3 VDC, ~750 mW moving / 50 mW standby
  • Controller: 64 MIPS, integrated into stage
  • Interface: Direct input of I2C, SPI, UART, Analog Servo

DK-M3-RS-U2-4.5-360 Rotary Smart Stage Developer's Kits are available now from New Scale at $995 (stock to 6 weeks).
