Pololu Power Polystack board
Power is an open-source printed circuit board by chickadee-tech, from the chickadee-tech/p-p repository on GitHub, published under the CC-BY-4.0 licence. It is a 2-layer board of 16.3 × 36 mm with 16 parts on 6 nets, routed with 69 tracks and 3 vias.
Its parts include 3 connectors, 3 fuses and 2 resistors.
This power board provides power to the base control board. It can either be used by mounting a Pololu voltage regulator directly to the pins or by using wire to connect to an existing regulator.
See the wiki for documentation.
This power board is part of the Polystack platform for modular microcontrol systems. More information on the platform can be found at polystack.org.

It measures 16.3 × 36 mm and has 2 copper layers, 1.6 mm thick.
16 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.
From the chickadee-tech/p-p repository on GitHub, at the commit this page was made from: the board is pcb/Power.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the CC-BY-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
