have anyone seen the m.2 externsion board anywhere available? I want to get a Rock Pi 4 as a replacement for an old raspi to run my home assistant on. I want to have it running from an ssd, to get rid of those stupid micro sd cards. But it seems that there is absolutely no availability of the m.2 extension board.
Is that board maybe open source? Are the gerber files available? in that case i would get the pcbs manufactured and soldered on my own.
