Back in August, when Opal Kelly announced the SYZYGY high-speed mezzanine bus specification, you just knew there would be a board coming soon with SYZYGY support. That’s board’s now here; it’s called the SYZYGY Brain-1; it’s based on the Xilinx Zynq Z-7012 SoC; and it’s available through Crowd Supply for $299.95. In addition to the Zynq Z-7012 SoC, the board includes 1Gbyte of DDR3 SDRAM, three SYZYGY Standard ports, one SYZYGY Transceiver port, a USB Type-C OTG port, a Gigabit Ethernet port, and an SD card slot. A Standard SYZYGY connector offers 8 differential-pair signals (or 16 single-ended signals) plus another 12 single-ended, impedance-controlled signals. The Transceiver SYZYGY connector offers four lanes of Gigabit-class transceiver connections plus additional 18 single-ended signals. The SYZYGY specification and the Brain-1 board obviously make good use of the Zynq Z-7012 SoC's excellent programmable connectivity and high-speed SerDes ports.

Now a brand new mezzanine bus interface standard is not very helpful unless there are mezzanine boards available, so Opal Kelly has developed a few:
