Questions
How big is the Openlog PCB?
It measures 36 × 36 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Openlog use?
19 parts, built around the SN74LVC1G58DCK, AT24CS02-MAHM-T and SN74LVC1G0832DBV. 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 Openlog KiCad files?
From the chickadee-tech/openlog repository on GitHub, at the commit this page was made from: the board is pcb/openlog.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Openlog design in my own project?
Its repository states no licence, so its author keeps all rights: ask chickadee-tech before reusing the design.
