Questions
How big is the Differential module PCB?
It measures 35 × 21.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Differential module use?
10 parts, built around the ISL32173EIBZ-T. 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 Differential module KiCad files?
From the SirBramble/Loguwu repository on GitHub, at the commit this page was made from: the board is 01_Hardware/03_Differential_module/differential module.kicad_pcb and its schematic 01_Hardware/01_Loguwu/Loguwu.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Differential module design in my own project?
Its repository states no licence, so its author keeps all rights: ask SirBramble before reusing the design.
