## QMTech SDRAM LX16

Although the QMTech SDRAM LX16 lacks on-board JTAG and USB/serial, it is a

very cheap and interesting board.  In fact, is so cheap that is possible buy

lots of boards and connect them via high-speed links!  :)

With an external Xilinx JTAG cable and an external USB/serial converter, the

board works very well and provides lots of IO pins.

The board includes:

- a XC6SLX16 FPGA w/ 256 pins

- 50MHz clock

- on-board SPI FLASH

- on-board SDRAM (classical MT48LC16M16A2

- two LEDs

- lots and lots of GPIO pins

As long the QMTech SDRAM LX16 is compatible with the QMTech development kit

based in the Artix-7, I managed to adapt the board and use the same

peripherals:

- USB/serial

- GMII PHY

- VGA interface

- more LEDs

- more switchs

- more GPIOs

Currently, only the USB/serial adapter is supported.
