USB Digital and Analog Input Output Interface

The USB interface board kit K8055 has 5 digital input channels and 8 digital output channels. In addition, there are two analogue inputs and two analogue outputs with 8 bit resolution. The number of inputs/outputs can be further expanded by connecting more (up to a maximum of four) cards to the PC's USB connectors. All communication routines are contained in a Dynamic Link Library (DLL). You may write custom Windows (98SE, 2000, Me, XP) applications in Delphi, Visual Basic, C++ Builder or any other 32-bit Windows application development tool that supports calls to a DLL. This electronic kit is rated a skill level of 4 by Velleman. (Advanced) Assembly is required. Also available as the pre-assembled USB Interface Experiment module VM110.

For a more advanced USB interface board with 33 inputs and outputs (analog and digital + 1 PWM) see the USB Input Output Interface Board kit K8061.
