Power Supply
Two voltage sources are supplied to the Accessory Bay:
- VCC 5V (4.75V to 5.4V).
- VCC Battery (12V to 16.8 V).
VCC 5V should be used to power the USB device. The combined total current for both VCC 5V pins is limited to 1.05A (the combined current for both pins).
VCC Battery can be used as a high-power supply for accessory hardware. The combined total current for both VCC Battery pins is limited to 1.1A (fuse: 1812L110/24DR) and the maximum power 18.5W.
