thx
Tested with Samsung QC3.0 charger. Can trigger 5v and 9v outputs. 12v mode did not work. With QC3.0 compatible Power Bank 5v, 9v and 12v modes works ok. Module can save mode: keep button pressed during USB cable connecting. Led start blink multicolors. Cycle to right mode with button. Long press saves mode. Disconnect and next connection module try trigger saved power mode. If mode is not supported, blinks blue led and power mode switch to 5v.
