• I did some more measurements.
    Battery voltage 2.78V
    3.3 V output : 2.5V
    LED1 turned on, Espruino running.
    I confirm that the transistor has just some mV of voltage drop.
    Since, I estimate the current over 35 mA, I have to look at the regulator datasheet to see if it is an expected value.
    Anyway, I manage with these figures!
