The board is equipped with a 2x3pin Molex connector offering standard 5V and 12V power supplies for

additional peripheral devices. Maximum current is 2 amperes for VCC/SVCC combined, and also 2

amperes for 12V. In the case of a power failure theses supplies are supported by the UPS circuit, but only

if the UPS is a Pb-battery. They are not supported if the UPS is capacitor-based.
