MAR2000 | Maradin MEMS Drive and Control Board

MAR2000 MEMS drive and control board

The MAR2000 is a FPGA based Drive and Control board. It is designed for Maradin's MAR1800S/L and MAR1500 1D MEMS-based scanning mirrors, for a variety of laser steering applications.
  • The MAR2000 is a versatile, configurable, and enables customization and adaptation for variety of scanning applications.

  • The MAR2000 has a full controlled, 1D electro-magnetic driving circuit. The driver is based on a full bridge driver, and could serve different scanning regimes as: Sine waveform Oscillations, Ramp, Steps, Point to point etc.

  • The MAR2000 utilizes the MEMS mirrors' capacitive sense signals for feedback control, with high accuracy. As the feedback control loop is designed within the FPGA, flexibility and versatility of the design is achieved.

  • The MAR2000 could be as a 1D Controller or in a "master-slave" configuration for 2D designs. The MAR2000 communication with the Host is through a standard UART interface.

  • KEY FEATURES AND BENEFITS

    • Powerful Full Bridge Electromagnetic driver

  • Closed Loop feedback control capabilities (digital/analog logic)

  • Low frequency noise reduction (1/F) by utilizing modulation of sensor signal

  • Support different scanning regimes: Sine, Step, Ramp

  • Option to have "master-slave" configuration for 2D applications

  • Sync signals output flexible design (peak, zero-cross, angle indication, alarm etc.)

  • UART/USB interface with external Host

  • 5V supply
