MAKESTUFF LX9 BOARD REV3 ------------------------ Features: * 80mm x 80mm, 4-layer PCB (KiCad format). * Xilinx Spartan-6 LX9 FPGA[1]. * Uses FPGALink[2] for programming & host communication. * Cypress FX2LP Hi-Speed USB interface (~45 MByte/s). * 46 FPGA I/Os on top edge-connector, well-grounded. * SPI-bus and 8 FX2LP I/Os on bottom edge-connector. * 16 MBytes of SDRAM. * SD-card slot. * 4 Mbit config flash (~40% free for application data). * Flexible power options. It is intended to be small enough and cheap enough to be used as a building- block for larger FPGA-based projects, and to be solderable at home with the bare minimum of tools (i.e no reflow oven, just a decent soldering iron). The component cost for a small (e.g 10-off) run comes to about $40 for each board, including the PCB. The design files are in KiCad format (http://www.kicad-pcb.org).
