    * This means that we need another boost converter or charge pump using the 1.8 V charged supercap energy to bring it up to 2.4 V to activate the 1381 voltage detector, and then power the BBC microbit enough to open the gate of the 2N3904 feeding itself longer directly from the energy source.    * This means that we need another boost converter or charge pump using the 1.8 V charged supercap energy to bring it up to 2.4 V to activate the 1381 voltage detector, and then power the BBC microbit enough to open the gate of the 2N3904 feeding itself longer directly from the energy source.
