From the project

Open-Source hardware for the Trinamic TMC5262

Notice: As of May 9th 2026, these boards have not yet been tested. The initial release of these boards contains the text 'PROTOTYPE' on the silkscreen to reflect this.

You will have errors on opening the files if you do not have the nasin-nanpa font installed, used by me for both marking my name and occasionally eastereggs.

These files contain LCSC P/Ns for the SMD components and, on the external board the two large capacitors. Specific P/Ns are not provided for other through-hole components.
