Older Versions

PCIe Screamer R02 (Discontinued)

_images/pcie_screamer_r02.jpg

PCIe Screamer R02 is a revised version of our successful PCIe Screamer.

Most notably PCIe lanes routing has been improved with better differential pairs impedance and length matching resulting in a better PCIe signal stability.

Existing software and gateware are fully compatible with this new PCIe Screamer R02 version.

PCIe Screamer R01 (Discontinued)

Quick Start

1. Select power source

  • For PCIe power supply, put the jumper on the left position.

  • For External supply via jack CN4, put the jumper on the right position. Input voltage: 5V to 15V max.

When the power supply is stable, the LED LD4 will be red.

2. Select Boot mode (R01 only)

SW2 selects the FPGA bootmode. Set it to Master SPI:

  • 1: ON

  • 2: OFF

  • 3: OFF
