@mardah oh... you mean pin change system, not extint. You can use it of course.

@JahFyahh - I still haven't managed to et round to it. I've been really busy since this project and its still hectic here. I'm sure i read a few reviews somewhere, here or google. Not sure.

@fets So far, I have only built the 5x5 board (but the others should be schematically identical). The only issue I have found so far is that I cannot get the ISP port to work. But I have checked and I have an identical setup on the 1.0 board and that worked, so I suspect the programmer is too weak to drive the net on this one. So it is not a board-issue per se, and might only be an issue on the 5x5 board as routing is the most complex on that one due to the size.

@mr_red I have a zipped snapshot of all the 3d step/wrl models that I used to build my projects so far. It was quite some work to gather them all and align with the footprints using the kicad stepup tools. It's not complete - still needs some more work:simple_smile: but it should help you or anyone else to get started into MCAD integration using FreeCAD and kicad stepup tools. Maybe it's not very easy to start when using free tools but hey they are "FREE" so we cannot ask for more. But the nice thing is that once you get used it will be really easy to do your stuff and to go forward. Oh and FreeCAD can be so powerful after you learn it - I was really amazed what you can do with it(it has it's quirks and downsides but once you master it - oh, well...). There's also: https://www.onshape.com/ - pretty powerful this one too and it has more advanced features than FreeCAD but the downside is that it's a cloud based solution: it's free for public documents but you never know when they will go to paid accounts only so yeah...I don't really like the idea to depend on something that it's hosted and the application is not on my PC along with the documents that I create with it. Cloud solutions have their flexibility but you're locked and you depend entirely on that hosted service. Ok, enough talking...I uploaded the zip file here: http://www.mediafire.com/file/kzh1l9uo40cpj1u/kicad_stepup_packages.zip

Hi @Siddharth-Velappan The warmup time of the MH Z19b is 3 minutes. So 2 is probably fine, but you could probably do 3 just in case. Although 2 would save your more battery time. Do you mind explaining your setup a bit more? I would love to do something similar but I do not know where to get started with the PIC microcontroller!
