I redesign project hardware board to single PCB and test first PCBWay manufactured board version successifully.

Also reduced PCB board size and upload latest schematics, PCBs and gerber files to project files.

This new board includes FTDI chip directly on same board and I put pull down resistor array on I/O unused RAM ports.

Now I solve bugs into AVR microcontroller firmware to work with external RAM, and create a simple C# PC program to send any data to RAM.
