BerryBase

BerryBase – the maker shop's own brand

Under the BerryBase name we carry products that we have selected, tested and added to our range ourselves. Behind this is the aim of offering makers exactly what is really needed in projects: solid quality, fair value for money and components that fit together.

The own brand grew out of our daily work with Raspberry Pi, Arduino and the like. Where standard products leave gaps, we fill them with our own items – from enclosures, cables and adapters to sensors and development boards.

If you buy BerryBase, you buy with our experience behind you: we know the products, use them ourselves and back them up with support and advice. That way an idea turns into a finished project faster.
