Power Supply
Power Supply Sources
The on-board power supply circuitry allows two power supply configurations:
from USB connector
from battery connector
USB powered When used as a USB device bus powered application, the AVRUSBKey can be directly
powered via the USB VBUS power supply line.
Battery powered The external battery connector should be used when the AT90USBKey is used as a
USB host. This mode allows the AT90USBKey to provide a 5V power supply from its
VBUS pin.
– Need of a female battery clip
– Input supply from 8 up to 15V DC (min. 100mA)
