Iris Cube->4*4 serial RGB dot matrix, can be expanded in series

Overview

Warning: The BOM is automatically generated and may not match the actual situation. Please do not use the BOM table to place orders directly. Everything is subject to the PCB package and schematic values.

Multiple light panels can be connected in series

Seven thousandths brightness. The control board below is [Iris Cube->Arduino MEGA2560 Iris Edition REV 1.3]

The brightness in the demonstration video is only turned on 1%, which is enough for me to read and write. If it is fully turned on, it will be very dazzling and I can only throw it away to make a street lamp.

The fourth question and answer of the first half of 2007 are here
[table=95%][tr][td]I won't translate this due to time constraints. It talks about how to use known parameters to estimate the energy loss of a device, and then estimate the life of the device based on
Question about LED circuit with over-current protection and self-recovery function?
There are 8 LED lights, and the current limit is 370mA. Should I reduce the current to a voltage that will not cause overcurrent even if only 1 LED is on, or should I reduce the voltage gradually? ???
