Velleman Kits & Projects

This computer interface board has a total of 33 inputs / outputs, including analogue / digital and a PWM output. The connection to the computer via the USB port is galvanically-optically isolated, so that damage to the computer is impossible thus providing a high level of secure implementation. All communication routines are contained in a Dynamic Link Library (DLL). You may write custom Windows* Applications in Borland Delphi, Borland C++ Builder, Microsoft Visual Basic, Microsoft VC or most other 32-bit Windows application development tool that supports calls to a DLL.

This application module may seem small but is big in performance - all depends on your programming skills. You can now create your own custom application without the hassle of making the hardware. All the buffered inputs and outputs are ready-made for you. The VM142 module features on-board LED, a relay output and audible warning buzzer. Make your own automation system with this Programmable Logic Controller (PLC) Suitable for home or automotive applications. All you need is one of our programmers like VM134 or K8076

The WMI167/VM167 is a very Small, universal USB powered & controlled I/O board. Add USB interface to existing equipment. You may write custom Windows Applications in Microsoft Visual Basic, Microsoft VC, Borland Delphi, Borland C++ Builder or most other 32-bit Windows application development tool that supports calls to a DLL.

The VM204 is an Ethernet controlled board with 4 relay outputs, 4 digital inputs and 1 analogue input.
It can send e-mail notifications when the status of an input changes and features an embedded webserver. Free apps are available for Android® and iOS®.

Do you own a RaspberryPi? Add the WPSH206/VM205 shield and you also own a digital storage oscilloscope!
All standard oscilloscope features are available and the application source code is supplied, so you can develop your own application.
As a bonus, you also get a 10-channel logic analyzer, a great tool to monitor digital signals.

Not compatible with Model Pi3B+

WMI8090, VM8090 module can be interfaced with your PC, it has eight relay channels which are controlled by your computer. Use your computer USB port to connect to the outside world. It will allow you to connect a load of up to 16A on each of the high power SPST relays. The board has space for extra VDR noise suppressors, it is provided with on board push buttons for test operating all the relays. Each channel also has LED to indicate condition of relay.

The Whadda WML116 unit can control DMX fixtures using a PC and USB interface. Test software and "DMX Light Player" software is included, a DLL is provided to write your own software.

Control your Arduino projects from anywhere in the world with a free app thanks to the Tuya IoT interface!

Plug the Tuya IoT interface module into your Arduino by using the included 4 male wires. Then connect your Arduino with the IoT Tuya cloud by simply installing the Tuyav library, which is compatible with ATmega chipsets (or AVR platforming). This will enable you to connect with the Tuya app over WiFi and lets you control up to 5 outputs.

Both the cloud and app are compatible with iOS® and Android®. It's also nice to know that the Tuya app and cloud are completely free and there aren't any sneaky subscriptions. Plus, the Tuya cloud is the largest in the world!
