Ecce ex oculis animalis.
/ˈek.ke/ Behold! Behold through the eyes of an animal.
ECCE (Ethological Capture of Creature and Environment) provides the hardware and software infrastructure for animal-borne sensing in freely behaving animals. This repository contains electronic schematics, PCB layouts, CAD designs, embedded firmware, and associated tools for building lightweight, untethered sensor platforms. By capturing environmental and behavioral information from the animal's perspective, ECCE supports neuroethological studies of how sensory input, movement, and neural activity interact to guide natural behavior.

Questions
How big is the Whoop rtc PCB?
It measures 20 × 20 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Whoop rtc use?
8 parts. 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 Whoop rtc KiCad files?
From the jsawbbo/ecce repository on GitHub, at the commit this page was made from: the board is topics/synchronization/rtc+backup/whoop-rtc/whoop-rtc/whoop-rtc.kicad_pcb and its schematic topics/synchronization/rtc+backup/whoop-rtc/whoop-rtc/whoop-rtc.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Whoop rtc design in my own project?
Its repository publishes it under the LGPL-2.1 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
