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 :)
Features
3.5 mm jack footprint
Switching voltage regulators
USB footprints without thru-holes
SPI OLED placeholder (thru hole probably)
FTDI 2232 usb-jtag chip
SPI flash chip
SDRAM chip
LEDs: 8 blinkleds, 1 usb led
RTC clock, quartz and battery
3.3V-5V I2C bidirectional level shifter for GPDI
GPDI is General Purpose Differential Interface, Electrically LVDS, mostly TMDS tolerant female receptacle more-or-less compatible with digital monitors/TVs
Todo
Completing FPGA IO bank shcematics blocks
Check SD card slot footprint
Oscillators (25/50/100 MHz)
rearrange PushButtons: 6 (2+4)

A B L D R
IR camera placeholder
OV767 color camera placeholder
2.54 mm external JTAG header
