Questions
How big is the XDuinoRail Debug PCB?
It measures 99.1 × 99 mm and has 2 copper layers, 1.6 mm thick.
What parts does the XDuinoRail Debug use?
170 parts, built around the ATTINY402-SSN, RP2040, BDR6133 and W25Q128JVSIQ. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the XDuinoRail Debug KiCad files?
From the chatelao/xDuinoRail-Decoder repository on GitHub, at the commit this page was made from: the board is kicad/xDuinoRailShield/xDuinoRail-Debug.kicad_pcb and its schematic kicad/xDuinoRailControl/control-board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the XDuinoRail Debug design in my own project?
Its repository publishes it under the AGPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
