Big buck
vkylamba/big-buck1This repository provides the hardware design and firmware/software for a high-voltage DC-DC buck converter. The converter efficiently steps down a high-voltage input (up to 600V DC) to 50V DC at a maximum power output of 1kW. The system includes WiFi and Bluetooth monitoring capabilities for real-time performance tracking and diagnostics.

Questions
How big is the Big buck PCB?
It measures 101.6 × 61 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Big buck use?
17 parts. 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 Big buck KiCad files?
From the vkylamba/big-buck repository on GitHub, at the commit this page was made from: the board is circuit/big-buck.kicad_pcb and its schematic circuit/big-buck.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Big buck design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
