Questions
How big is the EChook Nano PCB?
It measures 77 × 73.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the EChook Nano use?
141 parts, built around the TSR 1-2450, ZXGD3009E6TA, BAT54S,215 and KT-0805G. 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 EChook Nano KiCad files?
From the eChook/eChook-Nano-PCB repository on GitHub, at the commit this page was made from: the board is KiKad/eChook_Nano/eChook_Nano.kicad_pcb and its schematic KiKad/eChook_Nano/eChook_Nano.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the EChook Nano design in my own project?
Its repository states no licence, so its author keeps all rights: ask eChook before reusing the design.
