Mars AX3 FPGA Module Mars AX3 FPGA Module (Front)
Mars AX3 FPGA Module (Back)


The Mars AX3 FPGA module is equipped with a powerful, low-cost Xilinx Artix-7™ 28nm FPGA, Gigabit Ethernet, and fast DDR3 SDRAM, making it perfectly suited for high-speed communication and DSP applications.

The SO-DIMM form factor allows space-saving hardware designs, and speedy, simple integration of the FPGA board into the target application.



  • Low-cost, low-power FPGA of the latest generation
  • 35k-100k logic cells, 40k-120k flip-flops and 90-240 DSP slices
  • Uses the widely-supported and compact SO-DIMM form factor
  • Supports Gigabit Ethernet and analog inputs
  • Available in industrial temperature range
  • Powerful and compact FPGA board


  • Simple, low-cost and rugged assembly, in the industry-standard SO-DIMM form factor
  • Simple and low-cost integration due to the on-board Gigabit Ethernet interface
  • Fast boot times and support for execution-in-place (XiP) due to the 4 bit parallel SPI Flash
  • Lowest power consumption due to the high-efficiency DC/DC converters
  • Many IP cores are available from Xilinx, Enclustra and third parties.

Mars Heat Sink

Mars Heatsink (Top)

The Mars heat sink is an optimal solution to cool the Mars AX3 – it's low profile (less than 7 mm tall) and covers the whole module surface. It comes with a gap pad for the FPGA and four screws to attach it to the module PCB. With additional user configured gap pads, it is possible to cool other components on board as well.
