Older Versions¶
PCIe Screamer R02 (Discontinued)¶
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.

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
Once booted, FPGA prog done LED LD3 will be green.
Gateware & Software¶
PCILeech recommended.
