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.
