Note: The're no differences between 48 and 64-pin MCUs layouts, they use the same pin names, thus the same firmware applies.
First generation KSGER, all boards have a 7-pin OLED connector, no other versions seem to exist.
Second generation KSGER, all boards have a 4-pin OLED connector.
This is the most common layout used by other parties like Quecoo, Quicko, JCD, Handskit...
