sneakylizard123-4/Mega2560plus
Mega 2560+ is an upgraded version of the Arduino Mega 2560. It keeps the same form factor and pinout as the original so it still works with every Mega shield, but it adds an onboard sensor suite and an ESP32-S3…

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?
136 parts, built around the AL8860WT, TPS61288RQQR, DS3502U+T&R/C and TPS2117DRL. 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.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.
