Thanks for your schematic, i will make a nice drawing and add some furthers like serial/i2c combined connector selected with jumper. 3 kinds of lcd connectors (2 hd44780, 2x5 and 1x16, and 1 dogm) if possible (try to make a single side pcb and a minimum of via’s) . mosfet controlled backlight. 1x5 sil for iscp or do you want a RJ11 6/6 connector like ICD2 from microchip or both or a complete different one?. If possible I will use some good to be handled smd components. And of course own 5Volt stabilized power.
if somebody have more ideas please let me know.
