control mcu pinout
This is the unmarked IC labelled U1 on the silkscreen. , vcc is 4.24-4.3 volts

vcc ----| 1 5 |---- gnd
red pwm ----| 2 6 |---- blue pwm
? ----| 3 7 |---- green pwm
ir rx ----| 4 8 |---- ?

Funny bit is, the PWM signal is actually inverse. So they output a high signal to turn off the LED, and a low signal to turn on the LED. This can be proven by grounding one of the pwm output pins, which turns on the respective color of LED.
