   * **DSI Level adapter**: a bunch of resistors interfacing the FPGA's 1.8 V SSTL/LVCMOS I/O to DSI levels. More info on the FPGA core page.   * **DSI Level adapter**: a bunch of resistors interfacing the FPGA's 1.8 V SSTL/LVCMOS I/O to DSI levels. More info on the FPGA core page.
   * **DSI connector**: a standard 2x15pin 2mm pitch female connector with all DSI signals, power supplies and some GPIO pins for interfacing with the display. Since connector pinouts differ between displays the idea here is to use a tiny adapter board hosting the particular LCD's connector and its wiring.   * **DSI connector**: a standard 2x15pin 2mm pitch female connector with all DSI signals, power supplies and some GPIO pins for interfacing with the display.

The board was designed in Altium, I don't want to encourage piracy, so the sources will be here once I'll get them ported to Kicad. +Currently there are only PDFs available.

 +  * Standard Arduino shield size
 +  * 4 layers, FR4 (S + power + GND + S). Final stackup will be defined when I'll find a reasonable manufacturer (Itead looks promising...).
 +  * Arduino pinheads and surrouding PCB area can be chopped off to make the board smaller (70x37 mm)
