README

This project is based on the STM32F103C8T6 (Blue Pill) for controlling WS2812D (LED diodes). The LED cube is used for ambient lighting. Various animations can be displayed on the LED cube, which makes it very impressive and interesting.
How this project works
The STM32F103C8T6 and WS2812D (LED diodes) cannot be directly connected because they operate at different voltage levels. To solve this issue, the LED diodes and STM32F103C8T6 are connected using a logic level converter. A computer power supply is used to power the LED cube. It is necessary to use a computer power supply because when all 512 LEDs are lit, the LED cube requires a 20 A/5 V power source to function correctly. Programming code upload on STM32F103C8T6 with ST-Link.

Questions
What parts does the LED CUBE PCB use?
53 parts, built around the CH340C, TXB0108PW, BAT20JFILM and SMD1206-100/06N. 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 CUBE PCB KiCad files?
From the ladyM9/Led_cube repository on GitHub, at the commit this page was made from: the board is LED CUBE PCB/LED CUBE PCB.kicad_pcb and its schematic LED CUBE PCB/LED CUBE PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LED CUBE PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask ladyM9 before reusing the design.
