Thundercomm RUBIK Pi 3 (Qualcomm QCS6490): board outline, 8 mounting holes and connector positions — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/thundercomm-rubik-pi-3/ (sheet CC BY 4.0) Basis: Thundercomm RUBIK Pi 3 Datasheet V1.2.3 (section 2.4, Figure 2-4) and Thundercomm's official RUBIK Pi 3 3D model. Catalog version: 2026-10-20 Overall (mm): length 100.0, width 78.89, height 24.71 - Datum: lower-left board corner, I/O edge (all front connectors) along y=0, 40-pin header along the far edge. PCB 100.0 × 75.0, R4 corners, 1.55 thick. - Six Ø2.70 mounting holes (table); four of them form a 58.0 × 49.0 rectangle, the same spacing as the Raspberry Pi B pattern. Two further Ø3.00 holes at (4, 28.5) and (62, 65.5). - Front connectors overhang the I/O edge by up to 3.89 (78.89 overall). Tallest part is the dual USB-A stack, 16.4 above the board top. - The board underside sits 6.75 above the lowest point: the M.2 Key-M socket and SSD standoff hang below the board. - Modelled: PCB, holes, USB-A, USB-C, HDMI, RJ45, audio jack, 40-pin header, SoC shield, M.2 socket and standoff. Not modelled: FPC connectors, buttons, LEDs and pin tails. - All dimensions are exact nominal millimetres, true size, with no tolerance added. hole x (mm) y (mm) diameter (mm) 1 4.0 22.5 2.70 2 4.0 71.5 2.70 3 62.0 22.5 2.70 4 62.0 71.5 2.70 5 96.5 3.5 2.70 6 96.5 71.5 2.70 7 4.0 28.5 3.00 8 62.0 65.5 3.00 Files elsewhere (not hosted by Xem Studio; license as stated by the publisher): - Thundercomm: About RUBIK Pi 3 (documentation) — web — Publisher's page; dimensions are facts — https://www.thundercomm.com/rubik-pi-3/en/docs/about-rubikpi/ - Thundercomm: RUBIK Pi 3 product page — web — Publisher's page; dimensions are facts — https://thundercomm.com/rubik-pi-3/en/ - Edge Impulse: Thundercomm RUBIK Pi 3 board documentation — web — Publisher's page; dimensions are facts — https://docs.edgeimpulse.com/hardware/boards/thundercomm-rubikpi3 Free files (CC BY 4.0, Xem Studio; STEP + STL, 1 parts): https://xemstudio.com/files/hardware/thundercomm-rubik-pi-3/index.json API: https://xemstudio.com/api/geometry?object=thundercomm-rubik-pi-3
