Screw Terminal Shield for Giga R1

Official Hardware Mega GIGA R1 WiFi

Has anyone found a supplier of a screw terminal shield for the Giga R1 that works?
I tried this one from The Pi Hut but it did not work with the Giga

Has anyone tried this one?

cheers, Giles

Would you mind explaining why the one “didn’t work” and how the new one needs to be different?

Hi Jeremy, I'm not entirely sure but when I plug it into the Giga R1 it will no longer boot. I got onto the manufacturer and they said it was not tested for the R1.

Edit: I don't hugely get it because it's not a lot more than a board with a bunch of connectors on it...

So, an electrical issue and not a physical issue. The most likely problem is with the IO voltage circuitry. My suggestion would be to look for either a simple terminal shield or one rated for use with 3V boards (Due or GIGA). The simple terminal shields have terminal blocks around the edges and do not have any voltage regulator circuits on them unlike the one you tried. The other option you linked has 5V listed as its voltage and may have the same issue.

Thank you Jeremy, that's very helpful.

This one should work as it's Due compatible Screw Terminal Shield - Mega-Due compatible - SCREWSHIELDMEGASOLD

Or maybe this service if you're looking for something a bit custom Mega/Due/MegaADK/EtherMega Screw Shield

Excellent thanks Steve

For those of you finding this on a search - I found this, which is a simple screw-terminal setup:

I'm looking for Screw Terminal Shield for Giga R1.

I saw this thread, but it's not clear to me if Mega shields work for Giga.

Anyone nows where buy a shield specifically for Giga?

Thanks

Hi @daviddomene. The most important thing to keep in mind when using shields with the GIGA is that the GIGA uses 3.3 V logic levels, which means that if the shield's circuit would subject the GIGA's I/O pins to 5 V, that could do permanent physical damage to the GIGA board.

A screw terminal is just a simple set of connections between the header pin and the terminal blocks so it does not pose any such danger. So you can use any Mega screw terminal shield with the GIGA, no problem. Of course you still need to keep the 3.3 V levels in mind for anything you connect to the screw terminal, but that is no different than when using the GIGA without a shield.

I can confirm this one works, I'm using it. (on the Giga R1)

Thank you both for the info. Also it was an important advance the 3,3 V. I don't noticed when I bought the board. :slight_smile:

I have successfully used this ( Ultra-Small GPIO Terminal Block Breakout Board Module) for the Giga R1 with no issues. Its readily available on Amazon and easy to install. I highly recommend the screw terminals for any longer term usage. I have the Giga Display Shield hooked up too with the screw terminals and all works well.

Make sure you take note of some positional changes / additions of the pinouts compared to the mega board.

I have used this on the Giga. It works well. Just be careful, the GPIO pins on the terminal and Giga are not the same at the GND near D52.
