Questions
How big is the Cart ecp5 PCB?
It measures 100 × 60 mm and has 4 copper layers, 1.2 mm thick.
What parts does the Cart ecp5 use?
162 parts, built around the TLV62568DBVR-TP, W25Q128JVPIQ, 93C46BT-I/OT and FT2232HQ. 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 Cart ecp5 KiCad files?
From the nelgau/hicart repository on GitHub, at the commit this page was made from: the board is hardware/cart-ecp5/cart-ecp5.kicad_pcb and its schematic hardware/cart-ecp5/Display.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cart ecp5 design in my own project?
Its repository states no licence, so its author keeps all rights: ask nelgau before reusing the design.
