The Atom Project Overview
Atom is a micro modular robot designed as a test platform for studying swarm robotics, including multi-agent planning, control, and coordination. Up to 10 Atom robots can be in play at a given time, acting independently, or collaboratively. Paired with an overwatch application, state update information is streamed to each of the robots in a group broadcast, enabling rapid, low cost localization of each bot within the environment.
Communications
Each Atom is connected to a local Wifi network.
Localization
Localization of the system is handled by an overwatch system, which identifies Apriltags attached to the compute-chunk of each robot, and to the base station.

Questions
How big is the Chunk pannel PCB?
It measures 112.7 × 114.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Chunk pannel use?

Where can I download the Chunk pannel KiCad files?
From the paul-jo-dreyer/Atom repository on GitHub, at the commit this page was made from: the board is AtomPCB/chunk_pannel/chunk_pannel.kicad_pcb and its schematic AtomPCB/chunk_pannel/chunk_pannel.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Chunk pannel design in my own project?
Its repository states no licence, so its author keeps all rights: ask paul-jo-dreyer before reusing the design.
