50x50px outdoor LED art installation
At the Hacken Open Air 2021 (Gifhorn, Germany) event, this 5m by 3m large LED display was built.
It consists of 50 individual LED strings with 50 WS2812 LEDs each (50x50 pixels).
A central Raspberry Pi feeds 3 seperate STM32F722 via UART. These then generate the pixel data for the individual chains of LEDs. Each LED chain has it’s own 24V -> 5V buck regulator.
