The Micro-Robotics VM2 Controller Family

VM2 Controllers

VM2D Embedded Controller

VM2 is a family of powerful, easy-to-program single board microcontrollers intended for

  • Intelligent instruments
  • Portable and hand-held devices
  • Automatic test equipment (ATE)
  • Industrial automation
  • Process control
  • Protocol converters

Software Support

Programming Tools

Built-in Drivers


Application Boards

The VM2 plugs into the main PCB of your application to control all your user interface and I/O devices.

Or, if you don't want to develop your own application PCB we supply a range of products you can plug together to build your application.

Backup battery

VM2 uses a standard CR2032 Lithium battery to power the Real time clock and retain some settings when not powered. Not all applications require a battery. The battery holder is on the underside the board. Batteries must be purchased separately if required.
