There’s a fair amount of low cost boards powered by Xilinx Zynq Z-7010 and Z-7020 with dual core Cortex A9 processor and Artix-7 FPGA, but those who wanted to have PCIe ports or high speed transceivers had to go with the higher-end Xilinx Z-7030/7040/7050 with Kintex-7 FPGA fabric for a much higher cost. But Xilinx introduced Zynq Z-7015 late last year, a low cost Artix-7 FPGA + Cortex A9 SoC that also adds four 6.25Gbps SerDes ports and one PCIe Gen2 x4 integrated block. At least two modules based on the new SoC are currently available with DAVE Embedded Systems’ BORA Xpress and Trenz Electronic TE0715 Series.

The company provide a U-Boot and Linux 3.x.x BSP for the board. A development kit (BORA Xpress devkit) is said to be available with one SoM, one carrier board and all accessories required for immediate startup, but no details are currently provided for the kit on DAVE’s BORA Xpress page. More documentation should eventually be uploaded the site, and I could not find any pricing nor availability information.
Trenz Electronic TE0715 Series SoM
TE0715 Series modules are more compact than DAVE’s, and feature the following hardware specifications:
- SoC
- Xilinx Zynq 7015 XC7Z015-1CLG485C dual ARM Cortex-A9 @ up to 866 MHz with Artix-7 FPGA with 74K logic cells, 46K LUTs, 92K Flip flops, 380 KB RAM. 32 KB I-cache, 32 KB D-cache, 512 KB L2 for each core
- Xilinx Zynq 7030 XC7Z030-1SBG485C dual ARM Cortex-A9 @ up to 1GHz with Kintex-7 FPGA with 125K logic cells, 78K LUTs, 157K Flip flops, 1,060KB RAM. 32 KB I-cache, 32 KB D-cache, 512 KB L2 for each core.

The company claims the “latest documentation, design support files, reference design with source files and tools” are available on the Wiki, but for now at least, this looks very much like a work in progress. I can only see they recommend Vivaldo Webpack for development.
Trentz TE0715 Series modules appear to be available now for 319 Euros for the Z-7015 SoC version and 369 Euros for the Z-7030 SoC version. You may be able to find a few more details on Trentz Electronic’s TE0715 Series product page.
