pineapple-biped/pineapple_v3_pcb_basicBasic (simplified) version of the Pineapple V3 robot PCBs. The leg IMU is simplified, so this build drops the separate calf board and uses fewer signal headers than the full version.
Pineapple v3 arm is an open-source printed circuit board by pineapple-biped, from the pineapple-biped/pineapple_v3_pcb_basic repository on GitHub. It is a 2-layer board of 18 × 39.3 mm with 8 parts on 4 nets, routed with 18 tracks and 84 vias.
Basic (simplified) version of the Pineapple V3 robot PCBs. The leg IMU is simplified, so this build drops the separate calf board and uses fewer signal headers than the full version. Four boards total: base, base_A, thigh, and arm. Each board has its own folder containing the .kicad_pcb, .kicad_sch, and project files.
Exported Gerber files (ready for fabrication) are in the Gerbers/ folder — one _gbr.zip per board.

It measures 18 × 39.3 mm and has 2 copper layers, 1.6 mm thick.
8 parts. 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 pineapple-biped/pineapple_v3_pcb_basic repository on GitHub, at the commit this page was made from: the board is pineapple_v3_arm/pineapple_v3_arm.kicad_pcb and its schematic pineapple_v3_arm/pineapple_v3_arm.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 pineapple-biped before reusing the design.

Basic (simplified) version of the Pineapple V3 robot PCBs. The leg IMU is simplified, so this build drops the separate calf board and uses fewer signal headers than the full version.
