    Hello

    hi, I'm doing a conversion from a shop demo (powered by USB) to a battery powered unit.
    After checking the logic board on hand and the ones I can find on the net I realised one component is missing.

    I need some help in identifying this.

    Thanks.

    I think it might be a boost inductor? to get the voltage from 1.5 to 3?
