# ULX3S PCB
|
|
|
|
|
|
|
|
|
|
This is work-in-progress place for putting
|
|
|
|
|
some wishes of a small FPGA board.
|
|
|
|
|
|
|
|
|
|
Instead of describing in written,
|
|
|
|
|
it is better explained when drawn in kicad:
|
|
|
|
|
|
|
|
|
|
kicad ulx3s.pro
|
|
|
|
|
|
|
|
|
|
Currently this is only partial schematics and partial floorplanning.
|
|
|
|
|
PCB is not routed. Some footprintes are collected and some are incomplete.

An overview if the parts will fit in the space
|
|
|
|
|
how it will look.

|
|
|

|
|
|
|
|
From production of this, we are far, far away :)
