Carrier Board A203v2

We are depeloping an application where we have to use the digital outputs, however we do not find any kind of information about the electrical data given by the pinout.
The aim is to manage a relay through the digital outpus
Could you please provide me a full extended datasheet, as a consequence of the fact that the one that is available on the web site do not give all the information needed?

they provide almost no support and so far the drivers and the wiki for my 4GB production module don’t allow me to use a M2 E wifi module or my SD even after following their wiki and there doesn’t seem to be any real support for this product.
