^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) The LP50XX is multi-channel, I2C RGB LED Drivers that can group RGB LEDs into
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) a LED group or control them individually.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) The difference in these RGB LED drivers is the number of supported RGB
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) modules.
