If you require larger boards, please contact us through the ‘contact us’ page or email


Please note : A manufacturing number will be added to the silk screen – this is so we can find your boards from the factory.

This is a PROTOTYPING service – the finish may not be up to a production standard (but they will be fully functional) – if you require production boards

please contact us at with your requirements and we will get a quotation for you.
