What would I use this mainboard for?
Whether you want to build your own 3D printer, router or engraver, you will need a central controller to power, operate and control your device. This mainboard by Velleman is a universal, easy to use and high quality controller that contains a collection of inputs, outputs and interfaces. This will allow you to construct your own custom device of your own design.

Is this mainboard easy to use?
This mainboard is compact in design, completely assembled, and also contains screw holes so that it can be mounted into your device as part of your design and build. Connections onto the mainboard are done through push-on connectors to allow setup to be quick and simple. Each terminal is labelled to allow you to connect the right part to the right port first time. The design of the connectors will ensure that the polarity is also correct first time to prevent damage.

Will I have control?
The USB interface on the mainboard will allow you to fully control your device through a USB port. The Velleman VM8201 standalone controller (order code A77UX) can also be used in certain designs to allow control without a PC. Stepper driver boards can also be used to micro-control your motors for even more precision.
