STR-NCS32100-GEVK: Evaluation Kit for NCS32100XMNTXG

The STR−NCS32100−GEVK evaluation board provides hardware and a PCB rotary sensor for full demonstration of the NCS32100. The NCS32100 is connected to a fully functional PCB rotary sensor capable of sensing positions with an accuracy of <±50 arcsec. The board can be connected to a computer running the onsemi Strata Application, which provides a user interface for accessing position and velocity data, as well as a number of other auxiliary features. The NCS32100 evaluation board houses a full rotary sensor application with a master controller for accessing position and velocity data. Data is displayed through the onsemi Strata application (available for download from The evaluation board is programmed, calibrated, and ready for demonstration.
Features and Applications


  • Interfaces with up to 8 inductive coils
  • Supports Low Power Battery Mode
  • Delivers Rotary position and velocity over a 2.5 MHz RS485 Bus
  • Connection between external master and NCS32100 is implemented with a 2.5 MHz RS485 interface.
  • Backup battery voltage to the NCS32100 can be adjusted with R350 (potentiometer) from 1 V to 5 V. Clockwise turn lowers VBAT voltage.
  • Sensor portion of board houses a PCB inductive sensor that uses a rotor and a stator. The rotor is mounted above the stator with a fixture designed to mount to standard motors. The rotor can be turned by hand in the absence of a mounted motor.
  • Evaluation board houses a master MCU that is programmed to communicate with the NCS32100 over the RS485 interface. The STM 32 MCU also communicates data to an external computer via a virtual Serial COM port. Application is plug and play with the onsemi Strata App.
  • Evaluation board has been configured and calibrated to work with the attached 40mm PCB rotary sensor.
  • NCS32100 IC and PCB sensor portion of the board can be snapped off for application evaluation. The master portion of the board can be replaced with a different system master. Interface protocol details are defined in the NCS32100 Reference Design Manual
