Questions
How big is the Pdu PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pdu use?
128 parts, built around the ESP32-WROOM-32D, MAX17634BATP+, TPS2000CDGK and MCP7940N-I/SN. 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 SBC-PDU/unit-hardware repository on GitHub, at the commit this page was made from: the board is pdu.kicad_pcb and its schematic esp32.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pdu design in my own project?
Its repository states no licence, so its author keeps all rights: ask SBC-PDU before reusing the design.
