I didn't look beyond the advice in the BeBoPr User Manual: "Normally both connectors are wired to the same single 12 Volt supply." and "The stepper motors have a separate power connector, so these can operate at a higher voltage if required." Similarly, Figure 1 in the manual shows "12V system power input". So it's OK to put 24V on that connector then?
