USB Interface Experiment Board – Assembled – VEVM110

Product Description

USB Interface Experiment Board – Assembled – VEVM110

This usb interface experiment board 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.  Velleman VM110

A solder kit version of this electronic circuit is available – please see our part number VEK8055

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.
