Yes, I have schematics a we have analyzed it with my friend. We have mapped some components found on PCB to it.
I have got even some excepts of PCB components placement from Purims support later with instructions to replace some parts. But random soldering on the board when it is not fully clear which pars are on the png exports calms our motivation down. You have to understand it is calming down our enthusiasm. We are used to work, debug, design etc. on our own hardware or modules where we have full schematics and are really open. Eve my actual company work for ESA with 80 k EUR price tag is fully open and we are commercial busyness company and do not promote ourselves same way as a purism based on crowd funding… So Librem 5 now lays at home switched off. Yes, I am happy that I have contributed by my money to Posh and other open stuff development, I have no problem to leave Librem 5 on hold for year or for ever. I have lot other open stuff to do.
