Application Boards for the VM2
| In use, a VM2 controller is normally plugged into an 'application board'.
The VM2 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 application board, or have us do it for them. As these are mostly relatively simple circuits the investment in design and production facilities is relatively low. However it may not make sense for you to develop your own custom application board if you are just prototyping a project or have a small production run, so we offer a range of Standard Application Boards. The Application Boards shown below are compatible with VM2, VM2D and VM2L, though VM2L will not be able to drive some of the interfaces on Application Board 2. |

VM2 Application Board 2 - Product Code 5902
We put as many interfaces on this Application Board as we could
so you can explore the capabilities of the VM2 controller range:
- Ethernet
- Memory card socket (SD cards)
- Display and Touchscreen interface (display and adapter available separately, or as part of starter kit 2)
- USB connection to the VM2's Flash Filing System
- 2 x RS232 serial ports
- RS485 Serial Port (half-duplex)
- I2C Bus (3.3V or 5V) - to add more interfaces
- CAN Bus
- Alphanumeric LCD interface (3.3V or 5V)
- Loud speaker (plays PWM 'beeps' or WAV sounds)
- EEPROM for non-volatile application settings or parameters
- 4 x 4 Matrix Keypad interface, or 8 general purpose digital I/Os
- Power supply (Switch Mode: 7.5 - 28 VDC; 12VDC if using display)
VM2 Application Board 1 - Product Code 5905 (Breakout Board)
This board is called the 'Breakout Board' because all the VM2 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 - to add more interfaces
- Program mode and Reset switches
- EEPROM socket
- Prototyping Areas
- Powered by 5 - 16V DC, typically 50 mA
- Regulated 3.3VDC available
