spent the second half of today working on the second rev of the MNT Reform Next motherboard, where i decided to bring the connectors to the back side and also reorder them to minimize crossings (and mess) of the flat cables in the device in this upside down orientation. also made the board 5mm shorter to solve mechanical conflicts between the motherboard cables and the keyboard edge. a lot of work, but it'll pay off for sure.
this also means that i had to mirror (flip) all pins of these FPCs.
