Questions
How big is the PDU PCB?
It measures 136.5 × 104.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the PDU use?
196 parts, built around the SN65HVD230D, TPS82150SIL, BSS138 and 2N7002PW. 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 PDU KiCad files?
From the CASE-Lab/MARV-Hardware-Electrical repository on GitHub, at the commit this page was made from: the board is CCU - Combined Control Unit/KiCad/PDU_PCB_Rev1/PDU.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the PDU design in my own project?
Its repository publishes it under the CC-BY-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
