Questions
How big is the Heartbeat Logger PCB?
It measures 53 × 39 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Heartbeat Logger use?
78 parts, built around the TSV635IPT, BLM18PG471SN1 and NX3008PBKW. 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 Heartbeat Logger KiCad files?
From the Utstumo/Heartbeat-Logger repository on GitHub, at the commit this page was made from: the board is Heartbeat_Logger_Hardware/Heartbeat_Logger.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Heartbeat Logger design in my own project?
Its repository states no licence, so its author keeps all rights: ask Utstumo before reusing the design.
