Yet another Raspberry Pi cluster, which can chain up to 1+32 Raspberry Pi's!!!
The Pi on the Motherboard (master) is always turned on, while the other Pi's (slaves) are turned on/off by the master via I2C. The master can choose a slave to communicate with over UART.

Questions
How big is the Motherboard PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Motherboard use?
334 parts, built around the ATTINY13A-PU, LM358 and 2SA1015. 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 Motherboard KiCad files?
From the Terminus-IMRC/RPiCluster2 repository on GitHub, at the commit this page was made from: the board is Motherboard/Motherboard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Motherboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask Terminus-IMRC before reusing the design.
