Questions
How big is the Brick Buck PCB PCB?
It measures 158 × 158.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Brick Buck PCB use?
111 parts, built around the TPS54824RNVR, LT1641-1CS8#TRPBF, KT-0603R and SMDJ14A. 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 Brick Buck PCB KiCad files?
From the ParadigmEngineering/aks-2026-hardware repository on GitHub, at the commit this page was made from: the board is hardware/Brick Buck PCB/Brick Buck PCB.kicad_pcb and its schematic hardware/Brick Buck PCB/Brick Buck PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Brick Buck PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask ParadigmEngineering before reusing the design.
