Questions
How big is the MicroHard PCB?
It measures 197.5 × 107.7 mm and has 6 copper layers, 1.6 mm thick.
What parts does the MicroHard use?
193 parts, built around the MT25QL256ABA8ESF-0SIT, TPS54294PWP, TPS54325PWP and IS66WVO32M8DBLL-166BLI. 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 MicroHard KiCad files?
From the MH-Flight-Simulator-X/PCB repository on GitHub, at the commit this page was made from: the board is MicroHard/MicroHard.kicad_pcb and its schematic MicroHard/FPGA.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MicroHard design in my own project?
Its repository states no licence, so its author keeps all rights: ask MH-Flight-Simulator-X before reusing the design.
