I received an APM Led Buzzer card (from Charles Lakins).APM 2x LED / Buzzer Module
After searching VrBrain 4.5 documentation and Barone Rosso Forum, I got the right wiring data in order to use that module.
I had to reverse polarity of the module by unsoldering and reversing Leds and Buzzer on the card. Then I changed the wiring on the plugs.
LED_Setting in the APM param list is 11
Here is it on board
