Led information display using hub75 64x64 panel and Raspberry Pi Zero W to control it. Scripts included polls and displays data from different sources.
Display is custom build using 64x64 P2.5 HUB75e display module. It is connected to raspberry pi using https://github.com/hzeller/rpi-rgb-led-matrix library, which includes information about hardware connections. Display case includes DC/DC converter and temperature, pressure, and light sensors.
/boot/config.txt and /boo/cmdline.txt for RPi are included as these have important performance optimizations enabled. Following services are removed
