Questions
How big is the Fieldcam PCB?
It measures 39 × 119.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Fieldcam use?
135 parts, built around the AL8860WT, VEML6030, DS3502U+T&R/C and TPS61022. 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 Fieldcam KiCad files?
From the EmbryoPhenomics/FieldCam repository on GitHub, at the commit this page was made from: the board is electronics/fieldcam-backups/fieldcam-2025-08-06_172504/fieldcam.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Fieldcam design in my own project?
Its repository states no licence, so its author keeps all rights: ask EmbryoPhenomics before reusing the design.
