FEZ Relay Block and Pi

Hi All,
new here, sorry of this in the wrong place…
I have a Raspberry Pi and have bought a FEZ Relay Block to work with it:

My notes on the Pi say,
“GPIO voltage levels are 3v3 and are not 5v tolerant. There is no over-voltage protection on the board”
RPi Low-level peripherals - eLinux.org

Should it be OK to just connect the Relay Block to the GPIO pins, or will I need to protect it in some way?

Many thanks for your advice,

Yes it should work but of courses we can’t be responsible for any damage :slight_smile: since your board is not “gadgeteer”

Let is know how if worked and show some pictures please.

Can I also suggest that you use an Extender module with your Relay module? This will break out the pins of a relay module nicely and make it easier to wire up…

Thanks both, I’ll let you know how it goes :slight_smile:

Hi all,

I bought the extender but it has a (gadgeteer) 10pin IDC Socket

Where as the Relay Block connects to a JST3AA

Is there a good way to connect these, or should I just cut the cable and forget the extender?


it looks like you’ll need to get this as well…


or cut the cable if you wish…

I’m sorry, I’m a horrible person. I thought you had the gadgeteer relay module. :frowning:

I would say just snip off the plug on the relay block…

:slight_smile: - S’okey - :slight_smile: I might get a gadgeteer relay modeule next…
(presumably that would work same as the FEZ one with a Pi?)
In the meantime, I’ll just snip… Kind regards, -Duncan.
