Overview
Led controller is an open-source printed circuit board by markus-k, from the markus-k/led-controller-hardware repository on GitHub. It is a 2-layer board of 100 × 67 mm with 91 parts on 92 nets, routed with 907 tracks and 119 vias.
It is built around the MCP16301-E/CH, 24LC16B/P and LTV-814, with the DMP4015SK3 among its other parts. Its parts include 40 resistors, 14 capacitors, 13 transistors, 9 connectors and 5 ICs. It belongs with the radio and wireless and home automation and IoT boards and the STM32 boards of this library.

Known issues (rev 1.0)
- The 3.3V rail is missing a backup supply (from a big cap for example) and 12-24V presence detection to keep the µC and EEPROM alive for a few more milliseconds after the power went away. It's currently not possible to save the EEPROM on powerdown and thus periodic or event based writes are required, wearing the EEPROM more than needed.
- The 5A/Ch rating does not seem realistic unless smoking hot FETs are okay :)

Questions
How big is the Led controller PCB?
It measures 100 × 67 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Led controller use?
91 parts, built around the MCP16301-E/CH, 24LC16B/P, LTV-814 and DMP4015SK3. 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 Led controller KiCad files?
From the markus-k/led-controller-hardware repository on GitHub, at the commit this page was made from: the board is led-controller.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Led controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask markus-k before reusing the design.
