Yes while I think that while everyone on this forum is engaged in electronics, there are many sub-specialties, professional (I think that is your situation??) audio being one of them. I am sure there is some overlap but it is not reasonable to expect someone in computers, aerospace, or medical electronics to know all of the jargon for audio equipment, and vice versa.
@ML9104 well it’s not special jargon it’s just how t’s called this format.
That’s why I found strange you were not aware, being in the field.
Well, perhaps I did assume wrongly then
Although your reaction was quite disorienting me. I still don’t understand the link you submitted to me, while I just asked and clarified what I needed, instead of helping to find a solution that I guess it will be useful to other ones as well, or suggesting me an alternative name to search for the proper content.
Some standards are set by governments or industry consortium, or otherwise by one company which dominated a field for a while. Do you have any idea where the “lunchbox” standard comes from? If you can figure that out, it might lead you to an answer. As I indicated I had never heard of it. And I guess that is true for most of the people on this forum.
Back in the 1960’s a 144 MHz amateur radio transceiver made by Heathkit was nicknamed the “Benton Harbor Lunchbox.”
The lunchbox I have heard of I use to put my lunch in
It seems API trademarked lunchbox. http://apiaudio.com/about.php I guess anyone not in audio will not have heard about 500 series rack mounted audio modules. It also seems to be high end stuff, with the specs carefully guarded. If you join the VPR Alliance, they will send you the specs. http://apiaudio.com/vpr_alliance.php.
Your best chance is probably to get hold of a PCB and measure it. If you can’t find any KiCad or Eagle designs with google, there probably aren’t any publicly available.
Everyone here’s happy to help, but with what?
The link I submitted was to help you not only here, but also on other forums.
Instead of asking with a brevity that’s almost a record, perhaps your initial question could have been something like this:
“I’m looking for a KiCAD PCB template for a rack-mounted modular board known as “Lunchbox 500 Series” which is used in audio applications. Perhaps someone already worked with this.
Could someone point me in the right direction, or even have the template? Thanks.”
The original question was more like: “My car won’t start! Help*!”
If I asked you for an ARINC-600 template would you know what that is its a standard form factor after all
Is there some spec for this 500 series? Take an ATX motherboard, the specification for size, mounting holes and backpanel position are documented so I guess something like that must exist for this “standard”
A web search for “api” “500-series” “circuit board” dimensions returned this link as the fifth hit. Open Source Specification which seems to correspond to the API spec (Their language: The Workhorse itself has been designed to be compatible with the original API™ specifi cation and follows the fundamentals as employed by the VPR Alliance.)
