Confused by logic level converters

[Chester]

Hi guys, I have some 5v arduino nano's that I want to play with the RFM69's (3v3)

On the logic converters, there is this link that has 4 hv and 4 lv links: http://www.ebay.com.au/itm/351686714460

But it talks about having 2 inputs and 2 outputs on either side? So if I need to convert at least three links on the RFM, do I just need one of these that has 4 low and 4 high voltage points?

I guess what i'm asking, do these modules work in both directions or do I need to wire certain links to only specific channels on these modules?

Sorry if its not too clear, let me know if you need more info!

It works in both directions. The board is literally a rip-off of this board (even the description): https://www.sparkfun.com/products/12009 . Read the hook-up guide there
