Basis: Arduino UNO Q datasheet ABX00162-ABX00173 (Mechanical Information), with the UNO hole and outline coordinates from the Arduino UNO R4 WiFi datasheet ABX00087.
Catalog version: 2026-10-20

Overall (mm): length 68.58, width 53.34, height 10.1
- Datum: lower-left corner of the board (USB-C edge on the left, power/analog header edge at the bottom), board bottom at 0.
- Standard UNO outline 68.58 × 53.34, 1.6 thick, with the stepped edge opposite the USB-C port.
- Four Ø3.2 mounting holes at the UNO positions (table); same pattern as the UNO R3 and R4.
- Header tops 8.5 above the board top (10.1 overall). Digital header along the top edge, power/analog header along the bottom edge, each 1.3 in from the edge.
- Modelled: outline, holes and header rows. Not modelled: USB-C, Qwiic connector, LED matrix and the bottom-side high-density connectors; leave 2 mm clear under the board.
- All dimensions are exact nominal millimetres, true size, with no tolerance added.
