VM2 Controllers
VM2 is a family of powerful, easy-to-program
embedded controllers intended for
- Intelligent instruments
- Portable and hand-held devices
- Automatic test equipment (ATE)
- Industrial automation
- Process control
VM2 is also suited to many other applications
Free programming tools
The most important feature of our controllers is that non-programmers can quickly learn to program them, but experienced programmers are not limited in their ambitions.We supply free, simple-to-use programming tools for the VM2:
VM2 may also be programmed using third party tools.
Built-in Drivers
VM2 is supplied with drivers for- Colour Displays and User Interfaces
- File systems in internal Flash and SRAM
- File systems in SD cards and USB Flash drives
- Internet protocols
- Web servers
- Analogue and Digital I/O
- Audio output
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 standard Application Boards and I/O cards.
Product Variants
VM2 (5900)
This is the standard version of the controller.
Price
VM2D: Display driver (5907)
Has built-in TFT display driver for colour displays up to WVGA resolution (800 x 480).Note: For most small displays you can use the standard VM2.
Price
VM2L: Low cost, small memory (5901)
Application code size and the SRAM size are 64K Bytes each. Filing systems and graphic displays are not supported. Price 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. Price
Starter Kits
We supply a range of starter kits so you can evaluate the VM2 for your application.
