Questions
How big is the Logger v1 PCB?
It measures 70.6 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Logger v1 use?
123 parts, built around the ATA6561-GAQW-N, ESP32-S3-WROOM-1-N16R8, MAX-M10M-00B and OKL-T/6-W12N-C. 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 Logger v1 KiCad files?
From the ntakao2006-web/RaceCapture repository on GitHub, at the commit this page was made from: the board is circuit/logger_v1/tmp/order_review_backup_232312/logger_v1.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Logger v1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask ntakao2006-web before reusing the design.
