Overview
LED Module C is an open-source printed circuit board by lenaschimmel, from the lenaschimmel/bestelampe repository on GitHub. It is a 4-layer board of 70 × 79.1 mm with 91 parts on 58 nets, routed with 288 tracks and 209 vias.
It is built around the TMP1075DSG. Its parts include 29 connectors, 3 resistors, 1 capacitor and 1 IC. It belongs with the lEDs and displays boards and the ESP32 boards of this library.

DO NOT USE
This module is flawed in countless ways, and I really recommend to not use it in any way. Not as it is, not as a basis for modification.
I just uploaded it for transparency, because I talk a lot about it on the Progress page. You can read about it's problems there.
Goal
This board should make it possible to have up to 10 high power LEDs with different colors aranged in a slim (2mm) and short (20mm) line. A TLC59711 is used to generate the 10 PWM signals, but it is not driving the LEDs directly. Instead, a line driver, MOSFETs and series resistors are used to power the LEDs without the complexities of a constant current drive.

Questions
How big is the LED Module C PCB?
It measures 70 × 79.1 mm and has 4 copper layers, 1.6 mm thick.
What parts does the LED Module C use?
91 parts, built around the TMP1075DSG. 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 Module C KiCad files?
From the lenaschimmel/bestelampe repository on GitHub, at the commit this page was made from: the board is hardware/ledmodule/LED_Module_C/LED_Module_C.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the LED Module C design in my own project?
Its repository states no licence, so its author keeps all rights: ask lenaschimmel before reusing the design.
