Overview
Voltlog Microscope PDU is an open-source printed circuit board by voltlog, from the voltlog/Microscope-PDU repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 94 × 54 mm with 32 parts on 11 nets, routed with 64 tracks and 138 vias.
It is built around the AMSR2-7805JZ. Its parts include 8 capacitors, 4 connectors, 3 resistors, 3 ICs and 3 diodes.

My trinocular microscope has served me well for a few years but it has one annoying thing, the fact that it uses 3 different power adapters: one to supply power to the camera, one for the monitor and another one for the LED lights. This obviously takes up 3 different sockets on my extension lead and creates a mess of wires.
My solution to the problem is this Power Distribution Unit where I have a single 12V input and 3 outputs to feed the required voltages. The board was designed to be configurable, so you have the option of installing a standard footprint dc-dc converter if you need different voltages.

Questions
How big is the Voltlog Microscope PDU PCB?
It measures 94 × 54 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Voltlog Microscope PDU use?
32 parts, built around the AMSR2-7805JZ. 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 Voltlog Microscope PDU KiCad files?
From the voltlog/Microscope-PDU repository on GitHub, at the commit this page was made from: the board is Voltlog Microscope PDU.kicad_pcb and its schematic Voltlog Microscope PDU.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Voltlog Microscope PDU design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
