Velleman VM110N: USB Interface Card Module

Velleman VM110N

The Velleman VM110N USB Interface Card Module (Velleman Module Pre Assembled)

Let your computer monitor control the environment around it with the Velleman VM110N. With digital and analog inputs, digital open collector outputs (with on board LED indication) and your choice of two analog outputs or two pulse width modulation open collector outputs, this board has several applications.


Not enough inputs and outputs? No problem. You can connect up to four of these units. With so many inputs and outputs, the possibilities are endless. Use it for haunted house props, robotics, alarms, control relays, and the list goes on. With the supplied DLL (Dynamic Link Library) you can write your own custom Window (2000, XP, Vista and Windows 7) software applications in Delphi, Visual Basic, C++ Builder. You can also use the free Microsoft Express editions. The VM110N comes complete with test software and examples.


Or, if you're on a budget you may want to look at the K8055N USB Experiment Interface Board (soldering required) as an alternative to this premade kit, or the older K8055 model..
