Questions
How big is the OpenMD PCB?
It measures 72 × 50 mm and has 8 copper layers, 1.6 mm thick.
What parts does the OpenMD use?
220 parts, built around the INA241A2ID, LM5164DDA and EPC2361. 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 OpenMD KiCad files?
From the CrabLabsLLC/OpenMD repository on GitHub, at the commit this page was made from: the board is OpenMD.kicad_pcb and its schematic CurrentSensors.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the OpenMD design in my own project?
Its repository publishes it under the CERN-OHL-W-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
