Pi 4, rak2287 (although original versions used raspi3)

Appears to use an LED driver for an RGB LED - chip lp5562

Also, judging by the config.txt has an IO expander mcp23017

LP5562 is on i2c address 0x30 - https://www.ti.com/lit/ds/symlink/lp5562.pdf?ts=1646948675622&ref_url=https%253A%252F%252Fwww.google.com%252F

@MuratUrsavas any experience controlling one of these?
