Questions
How big is the Sip lpddr2 PCB?
It measures 66 × 42 mm and has 4 copper layers, 0.95 mm thick.
What parts does the Sip lpddr2 use?
114 parts, built around the 74AUP1G17GW, USBLC6-2P6 and BSS84. 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 Sip lpddr2 KiCad files?
From the vd-rd/sbc_microchip_sama5d2 repository on GitHub, at the commit this page was made from: the board is module-sip/sip_lpddr2.kicad_pcb and its schematic module-sip/cpu.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sip lpddr2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask vd-rd before reusing the design.
