VM-1 Application Boards
In use, a VM-1 controller is normally plugged into another board. The VM-1 provides the CPU functions and the raw logic-level I/O signals; the 'application board' provides interfaces to the system to be controlled.

Often our customers will design their own VM-1 application boards, or have us do it for them. As these are mostly very simple circuits, the investment in design and production facilities is relatively low.

However it may not make sense for you to have your own custom application board if you are just prototyping a project, or have a small production run. That's why we've developed a range of Standard Application Boards for you.

VM-1 Application Board 1 - Product Code 5802

VM-1 Application Board 1

This is the original VM-1 Application Board.

Features:

  • RS232 and RS485 serial ports
  • Analogue, digital and pulse I/O
  • Keyboard interface
  • Graphics* and alphanumeric LCD display interfaces
  • Two I2C buses
  • SPI
  • Dallas 1-Wire® bus
  • EEPROM
  • Powered by 8 - 30V DC, typically 150 mA
  • Regulated 5VDC output
*The Graphics LCD interface on this board is for displays controlled by the Hitachi HD61830B, Sanyo LC7981, or Toshiba T6963C, and some other LCD controllers. These displays are typically 240 by 128 pixels. See the 'Module Board' for QVGA displays.

VM-1 Application Board 2 - Product Code 5805 (Breakout Board)

VM-1 Application Board 2

Also known as the 'Breakout Board' because all the VM-1 pins are taken to prototyping areas for you to develop your own circuits. To get you started it has power, serial, and I2C interfaces already fitted. These are easily removed or bypassed if you don't want them.

Features:

  • RS232 level shifters & D9 connector on Serial Port 1
  • I2C bus connector on Bus 1
  • Prototyping Areas
  • Flash Programming Socket - for fast duplication of your application.
  • Powered by 8 - 30V DC, typically 80 mA
  • Regulated 5VDC output
  • May be used to program free Venom updates

VM-1 Application Board 3 - Product Code 5811 (Module Board)

app board 3

This VM-1 Application board, also known as the 'Module Board', features two sockets for modules that connect to the VM-1 system bus. One module position is expected to be used with the Ethernet Module, the other includes comprehensive support for the QVGA Driver Module.

There are FFC connectors for the popular Hitachi SP14Q006 display and associated touch screen, as well as 0.1" pin headers which can be adapted for many other display and touch screen types. A DC-DC converter provides adjustable bias and contrast voltages.

The mounting hole positions are also compatible, allowing the board to be mounted on pillars behind the display:

Other features

  • 2 serial ports with socketed RS232 line driver ICs
  • 2 I2C Busses
  • 256 byte EEPROM for non-volatile parameter storage
  • Alpha LCD interface
  • 4x4 keypad interface
  • All the channels on VM-1's JP2 are brought out to a single 0.1" pitch connector pattern for customer expansion
  • Powered by 8 - 30V DC, typically 250 mA with modules on board
  • Regulated 5VDC output for use by other circuits
