Questions
How big is the TrashFlash PCB?
It measures 108 × 60 mm and has 6 copper layers, 1.56 mm thick.
What parts does the TrashFlash use?
157 parts, built around the STM32L471QEI6, CC110LRGPR, TPS63900DSKR and LP5024RSMR. 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 TrashFlash KiCad files?
From the serillius/TrashFlash repository on GitHub, at the commit this page was made from: the board is TrashFlash/TrashFlash.kicad_pcb and its schematic TrashFlash/Battery_Management.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TrashFlash design in my own project?
Its repository states no licence, so its author keeps all rights: ask serillius before reusing the design.
