@David: I have never seen any less than 0.2".   Very handy.....

We don't allow them to be sent to Australia -- we pretend 0.2" is the smallest you can get, then we laugh our socks off as we watch you trying to design using the 0.2" versions LOL

@Max - "In fact the screw-terminal blocks we are using have a 0.1 inch pin pitch"

Niiiicce....I should have noticed that from the photo.  I have never seen any less than 0.2".   Very handy.....

@blavigne: I'd love to get a couple of those Bensonfruit proto boards.  Is there a way to acquire them?

Let, me have a word with Duane -- email me at my personal email max@CliveMaxfield.com (but as per this blog, I might not respond for a couple of hours)

Max,

  My son and I are just getting into Arduino/robot building.  I'd love to get a couple of those Bensonfruit proto boards.  Is there a way to acquire them?

@David: Given that most PCB terminals are 0.2 inch spacing, and the header pins are 0.1 inch...

In fact the screw-terminal blocks we are using have a 0.1 inch pin pitch, so they are one-for-one with the header pins...

@Max, Duane yeah. it is a tradeoff.  Given that most PCB terminals are 0.2 inch spacing, and the header pins are 0.1 inch, you could maybe put the jumpers between the header and the terminal bolocks, and stagger them so they don't take up too much space, but the board would then be that much wider.   ANd I suppose that once you have wired your jumpers, you're unlikely to want to change them very often.

@David @Duane: As I recall we did discuss doing something like this -- but the header pin connectors protrude above and below the board (so as to allow for the stacking of shields), which means we need to have access to both the terminal pins AND the screw-block pins INSIDE of the header pin connectors so that we can connect them to the prototyping area...

David - I thought about doing that, but didn't want to add the additional board space. If I were to go that route,  I'd probably end up with a block of jumpers that would all all permutations of connection.

@David: I did a PCB graphic but I cannot get it into my post, I'll email it to you Max.

I await your email with dread anticipation, but .... you may have to wait longer than usual for a response, as explained in my blog Shut Down Your Email & Reduce Your Stress

@Max, Duane

Were I doing this, I'd have a jumper next to each header / Screw terminal that you could select (with one of those little black jumpers that fit over pins).  More PCB space, but much easier to use.   I did a PCB graphic but I cannot get it into my post, I'll email it to you Max.
