The Better Breadboard Power SUpply is an alternative to the cheap Chinese knockoff breadboard power supplies. Features: USB-C power input SMD PTC resettable fuse support Large direct-solder power input pads THT pad for power LED or capacitor 20 2.54mm pins for rock-solid connection to the breadboard
I originally designed this for a 16-bit CPU project to tackle the problem of power distribution over a large amount of breadboards (15+). This little PCB turned out to work fantastically and I'm quite happy with the results so far. Next steps would to make the Vcc/Gnd connections configurable based on different breadboards and add a cooler logo. Also, I would like to use the high-power USB-C connectors, rather than the data version.

Questions
How big is the Panel PCB?
It measures 59 × 85.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Panel use?
250 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 Panel KiCad files?
From the LRFPV2/BBPSU repository on GitHub, at the commit this page was made from: the board is breadboard_psu_v2/pannelized/panel.kicad_pcb and its schematic breadboard_psu_v2/breadboard_psu_v2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Panel design in my own project?
Its repository states no licence, so its author keeps all rights: ask LRFPV2 before reusing the design.
