    I have tested a powerbank with USB C power delivery as an alternative powersource for the trains.

    The small decoy/trigger board between powerbank and nodemcu/L9110 tells the powerbank to deliver 9V.

    Unfortunately the 50cm USB C to USB C cable takes alot of space.

    It works quite well, the powerbank has 5000mAh/18,5Wh and its power switch can be toggle through the roof of the BR 146 loco.

    Nice work! How did you get 5 volt for the D1 mini?

    Small protoshield for the D1 mini, it’s compatible with the sensor and switch controller:
