Questions
How big is the System voltages PCB?
It measures 104.1 × 83.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the System voltages use?
48 parts, built around the INA240A4D, LM5109BMA, BA50DD0T and TPS2511QDGNQ1. 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 System voltages KiCad files?
From the kt140/ECE445_SeniorDesign repository on GitHub, at the commit this page was made from: the board is Schematics_kanin/system_voltages/system_voltages/system_voltages.kicad_pcb and its schematic Schematics_kanin/buck_converter/buck_converter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the System voltages design in my own project?
Its repository states no licence, so its author keeps all rights: ask kt140 before reusing the design.
