hi,
in order to work towards getting the laptop out in phases i'm looking to create an intermediary design that utilises the exact same PCB1 from the laptop, exact same LCD, without the STM32F board (PCB2) and without the battery charger board (PCB3)... which in effect makes an "LCD monitor" when utilised with a passthrough Card or an "all-in-one PC" when utilised with a card that has a processor in it.
a review of the (simple) schematics for PCB4 would be really useful, although they are in fact very very simple.
please note though that i will be delaying prototyping PCB4 and PCB1 until the latest micro-desktop revision (1.7) has been prototyped and confirmed working with its SD/MMC level-shifting. i missed that bit... so do not wish to waste backer funds by potentially making a mistake on the micro-desktop 1.7 PCB that's *duplicated* on laptop PCB1.
