I made a basic clock using this module with an Arduino and a DS1307 RTC module. My code has support for this module and the earlier revision (include the appropriate define in the .h file). https://github.com/azrobbo/Arduino-Clock-Seven-Segment

Thanks for the quick reply.
I probably should have started my comment a little more positive. I really like this board, which is why I was so frustrated when trying to mount it. (If I didn’t like it, I would just use something else).
And yes, you folks are doing an awesome job of adding mounting holes onto your newer boards. I can deal without mounting holes for the vast majority of boards. It just these ‘external facing’ boards where the lack of mounting holes can be frustrating.
And sorry to assume a lack of demand for compact size, I was just looking at comments. I’m sure you get a large volume of email requests in addition to these.
“Think about all of the extra wasted space that you would need to add stand off holes to this board.”
I realize this is a very old post, but it’s not wasted space if its required to for the board to be useful.
You could also save a lot of ‘space’ by removing the 7-segment displays. Why don’t you remove those? Because they’re needed for the module to be useful. The same thing is true for a mounting method. (its needed for this module to be useful beyond prototyping.)
This isn’t some module that you can just hot glue to the side of a project box and be done. This module needs to be mounted in a way that is visible from outside the box and also flush with the box edge. This is very difficult to do when the current module.
You mention “we are trying to build stuff to be compact.” Who is demanding these products be compact? I don’t see a single person asking for a smaller board. Yet I see many asking for mounting options.
Sparkfun - Can you at least give us a thru hole connection in each corner of the board where I can solder a single pin? This would at least allow me to rig up standoffs using 1-pin headers.

This is a great screen, but missing a KEY requirement for me. Are you planning on carrying the uLCD-43PCT(GFX) version that has Capacitive Touch built in? Resistive Touch is so 2005.

The model I refer to in the post above relates to an item that was not purchased at Sparkfun.
It does hwoever seem to indicate that there are versions of MagJacks/PulseJacks that support 100BT and/or 10BT.
The Model that I received, a PulseJack J00-0065NL supports up to 100BT according to the datasheet at: http://ww2.pulseeng.com/products/datasheets/J414.pdf
There are some other model #’s listed in the datasheet as only supporting 10BT.

Check out the mbed product. http://www.sparkfun.com/commerce/product_info.php?products_id=9564
It has the same processor as this board, but also has its own IDE and library that dramatically simplifies things - much like the Arduino does for the ATMega. You can go to their website mbed.org and get a feel for what people are doing with it. Its very Arduino-ish, just with a smaller community, but much faster processor.
The major limitation of mbed is that the IDE is only available online, meaning you have to be connected to the internet to code or compile. There’s also a lack of “target” boards once you’ve got a working prototype and want to move it into production.
Despite these limitations, I’m moving most of my development over to the 1768 because of it. (I’m in the process of spinning my own target boards, since a cheap one doesn’t really exist in the marketplace yet.)
Thanks much for the links. In particular, the micropendousx project looks interesting.
Unfortunately, it still has a lot more accessories on-board than what I’m really after. But maybe I can use their files and slim it down.
What I’m really after is something like the “arduino pro mini” but based on the NCP1768 - i.e. nothing on the board except the absolute bare minimum. That way its cheap and can be used anytime I need a 1768 without spinning up my own board.
I’m glad to see that Sparkfun is starting to stock more CM3 dev boards.
What I really want is a 1768 “stamp” board that’s pin compatible with the mbed. Something along the lines of the arduino pro-mini based around a 1768 on it. Something to allow us to rapidly prototype on the mbed, then port it to this “stamp board” for productions. (You can leave the internet support chip off the stamp to keep costs down; target price 20-25)
