Standard PCB Measurements and Dimensions
05/17/2024 at 14:29 • 0 commentsThis page is for me to drop measurements and dimensions on various PCB layouts, especially for ones I've spent way too long searching to find. Hopefully we won't have to dig as deep to find them after this.
First one: Pico-ITX. For some reason getting dimensions for this is very difficult. Here's measurements for a reference design: I found it in this PDF: https://linuxdevices.org/ldfiles/misc/Pico-ITX_Form_Factor.pdf
Nano-ITX:It's from https://macroems.ru/modul-nano-itx/
Mini-ITX, just so we're complete:From https://cdn.instructables.com/ORIG/FJD/TETT/GU59XBKK/FJDTETTGU59XBKK.pdf
I'll add more to this later if there's some other board layout I can't find info on. -
Test Page
07/28/2019 at 20:06 • 28 commentsDo whatever here, making this page so I can do experiments on HaD comments etc
Edit:
SUCCESS. WE HAVE MADE A COMMENT WITH NON-PRINTABLE CHARACTERS ONLY! -

That would be very interresting!
