Questions
How big is the Dcdc breakout PCB?
It measures 85 × 40 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Dcdc breakout use?
24 parts, built around the I3A4W008A033V-001-R. 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 Dcdc breakout KiCad files?
From the Poppy-Robotics/dcdc-breakout repository on GitHub, at the commit this page was made from: the board is dcdc-breakout.kicad_pcb and its schematic dcdc-breakout.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dcdc breakout design in my own project?
Its repository states no licence, so its author keeps all rights: ask Poppy-Robotics before reusing the design.
