Questions
How big is the DDRN Hardware PCB?
It measures 33.3 × 54.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DDRN Hardware use?
55 parts, built around the LORA-E5-HF, BMP390L, MAX1932ETC+ and W25Q32JVSSIQ. 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 DDRN Hardware KiCad files?
From the davidfobar/SCRAM repository on GitHub, at the commit this page was made from: the board is DDRN_Hardware/v0.1/DDRN_Hardware.kicad_pcb and its schematic DDRN_Hardware/v0.1/DDRN_Hardware.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DDRN Hardware design in my own project?
Its repository states no licence, so its author keeps all rights: ask davidfobar before reusing the design.
