Questions
How big is the Pcie active backplane x16 4layer PCB?
It measures 202 × 160 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Pcie active backplane x16 4layer use?
47 parts, built around the TPS22810DBV, TPS54302 and SS34. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Pcie active backplane x16 4layer KiCad files?
From the TeinkBR/pcie-active-backplane repository on GitHub, at the commit this page was made from: the board is hardware/pcie_active_backplane_x16/pcie_active_backplane_x16_4layer.kicad_pcb and its schematic hardware/pcie_active_backplane_x16/brochure/50_product_brochure_A1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pcie active backplane x16 4layer design in my own project?
Its repository states no licence, so its author keeps all rights: ask TeinkBR before reusing the design.
