XIAO SAMD21 sleep current after power LED removal

Products & Technology
#1

Hello,

I am trying to reach as low sleep current as possible, should be somwhere around 5uA.

Yet for some reason I have 22uA consumption. Any working demo code demostrating the lower current consumption?

#2

Any suggestion, can’t believe I am the only one noticing this?

#3

I reach 9.3uA after removing the power LED. Worth noting I feed the board on the 3v3 pin

Code:

    USBDevice.detach(); // Turn off USB interface
    ADC->CTRLA.bit.ENABLE = 0; // disable ADC
    for (uint8_t i = 0; i < NUM_DIGITAL_PINS; i++)
    {
        pinMode(i, OUTPUT);
        digitalWrite(i, HIGH);
    }
    Utils::sleep_s(10);
    while (1)
    {
        Utils::sleep_s(10);
        LowPower.sleep(5000);
    }
