It measures 43 × 24.8 mm and has 4 copper layers, 1.6 mm thick.
117 parts, built around the TPS62933DRL and SL2.1A. 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.
From the bitluni/t-800-CPU repository on GitHub, at the commit this page was made from: the board is PCB/RP2354A_Cluster/RP2354A_Cluster.kicad_pcb and its schematic PCB/RP2354A_Cluster/RP2354.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask bitluni before reusing the design.
