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.

Currently PCB is not routed. Only some footprintes are being collected and some are incomplete,

Here are just so get some insight how will it all physically fit and look.

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

Features

3.5 mm jack footprint

Completing FPGA shcematics blocks and checking fitness for the footprint

Switching voltage regulators

USB footprints without thru-holes

SPI OLED placeholder (thru hole probably)
