@poczta I don't have an IR in front of me to confirm, but from my notes this should be the pinout (in order):

Tip - Red - 3.3V Ring - White - RX (IR Wide Receiver) Ring - Green - TX (IR Blaster PWM) Sleeve - Black - GND

However, this will be at your own risk. Let me know if you need further info!

Regards,
Anton
