Correction to the original wording: the owner chose the features and layout and reviewed the design; ChatGPT/Codex generated and revised the schematic and PCB, routed the board, ran the CAD checks, and prepared the files. The original first-person wording incorrectly implied that the owner personally performed those steps. This correction was also entered by Codex.

The current design has six MX switches in a 3-by-2 grid, a clickable EC11 encoder at the upper left, a 0.91-inch OLED immediately to its right, and a XIAO RP2040 with USB-C accessible at the top edge. The board is 86.5 by 88.5 mm with two copper layers. The public repository includes KiCad source, connection-check reports, a pin map, BOM and Gerbers.

This remains a design prototype: it has not been assembled or electrically tested, and the supplied parts still need footprint and case-fit confirmation. The displayed tracked time is not a claim of 40 hours of recorded human work; its eligibility, including any AI execution time, needs organizer review.
