Notes
- 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.
