After the Tiny LED Cube, the logical next step was one double the size (or 8x the volume)!
The LED Matrix panels are just 4 of the smaller ones joined together and uses the same MCU board to run it. This time with an accelerometer added, so the rainbow animation always flows downwards. The cube is powered from 5V through a USB cable this time and I took it to the 2019 Hackaday Superconference to show off
