Questions
How big is the Payload carrier PCB?
It measures 47.9 × 50.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Payload carrier use?
52 parts, built around the TPS73733DCQR and B340A. 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 Payload carrier KiCad files?
From the ULAS-HiPR/tortilla repository on GitHub, at the commit this page was made from: the board is payload_carrier.kicad_pcb and its schematic payload_carrier.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Payload carrier design in my own project?
Its repository states no licence, so its author keeps all rights: ask ULAS-HiPR before reusing the design.
