Part review – ScrewShield for Arduino

Hello interested readers

Today we are going to examine a part that makes connecting external wires to an Arduino easier than trying to electrocute yourself – the Wingshield Industries ScrewShield. Is is such a simple and useful thing I am almost angry at myself for not getting one earlier. Better late than never!

The ScrewShield allows you to connect wires to all of your Arduino I/O pins via PCB-mounted terminal blocks. And it is also designed as a shield, so you can stack more shields on top like any other. Now to save costs it comes unassembled, but that isn’t a problem. Here is the contents of the bag upon arrival:


The quality of the PCBs are very good:


And no instructions were necessary – so time to fire up the soldering iron and fume extractor:


The first thing to do was jig up the socket pins with the PCBs using my favourite method, a lump of blutac:


Then it was a simple matter to turn it over and solder away; then repeat the process for the other wing. Time for a quick break to see how they look:


Once the sockets have been soldered in, the next step was to connect the terminal blocks together for each appropriate line:


And then time for another soldering session:


And we’re done. Looks kind of like a Lego spaceship from my childhood:


You can never have too many Arduino shields:


Another use for the ScrewShield is to make it easy to connect multi-core wires to a breadboard. Using PCB terminal blocks is usually difficult as the pins are a fraction too large for the holes in the average breadboard. However you can only use the analogue shield to do this, as a reader has pointed out, the pin spacing for the digital side is a little off:


Nice one. It’s always great to have a product with more than one use. So there you have it. Another inexpensive, interesting and very useful part for the Arduino fans out there. If you use an Arduino – you really should get one of these.  And if you made it this far – check out my new book “Arduino Workshop” from No Starch Press.

    Nce mn revew…

    I feel lke such a Dlbert! I have two of these shelds and never thought for a second of usng one of the sdes as an adaptor for a breadboard… It s such an obvous thng to do!

    Got your ste on RSS, fantastc resource.

      Absolutely, t occurred to me at the last moment when a breadboard was starng at me n the face. :)
      Thanks for readng and catchng up – your ste s also a wealth of nformaton. Nce one

    Well I feel doubly dumb; I’m one of the desgners of the ScrewSheld and I never thought of the breadboard trck ether. Nce one!

    Frst of all, nce blog, keep up the good work !

    Regardng the use of blutac to hold components whle solderng, I’ve found that the blutac I use (branded “UHU patafx” here n France) wll melt due to the heat. When I remove the blutac, there s always some of t that stays on the board/component. I have to wat for t to cool down so that I can get back most of the remanng blutac. Do you experence the same thng ?

    As for “usng one of the sdes as an adaptor for a breadboard”, the non standard pn spacng s what put me off buyng a genune Arduno (I love boardunos though ;-P)

      Hello, thank you for readng!
      Yes, the blutac s a bt of a kludge – smple and works. The frst couple of tmes I tred t… yeah some melted a lttle. Ths mght sound crazy and very unscentfc: I use the same blob repeatedly, t must be a few months old now – t gets a lttle harder as t dres out. Now t doesn’t melt or get affected by the heat at all.
      Boardunos rock. I’m startng to just breadboard the ATmega328 as well, e.g.:

    Only one of the par of screwshelds can be used wth a breadboard. The spacng on the connectors on the other one s a lttle s a lttle wde. The two gnd pn are connected together on the screwsheld so be careful how you use t.
