Does anyone know the technical specs of the step down voltage regulator used in the Power Up Hub (No. 4)?
I'm interested in creating a rechargeable pack for the hub and wondering if it can handle 7.2-7.4v or 10.8-11.1v packs. From the PUP Motor Specs it looks like it somewhat different to the Power Functions train motor which used a 7.2v rechargeable pack, but the efficiency was much better for that motor at 7.2v vs the new PUP motor, so i'm wondering if LEGO intends to use a 3S pack for the new PUP motors.
The PUP hubs also have stepper motor drivers included, are any of the PUP motors actually steppers?
