Questions
How big is the DisplayU Sisterboard PCB?
It measures 80 × 28.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DisplayU Sisterboard use?
68 parts, built around the AP2112K-3.3TRG1, LTC4001EUF#TRPBF, XPEBRD-L1-0000-00901 and 04941.25NRHF. 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 DisplayU Sisterboard KiCad files?
From the dersian/embeddedBikeSafety repository on GitHub, at the commit this page was made from: the board is KiCad/Production/DisplayU_Sisterboard/DisplayU_Sisterboard.kicad_pcb and its schematic KiCad/Main/EBS_Main/EBS_Main.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DisplayU Sisterboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask dersian before reusing the design.
