3.5 Power Sources
The SAM B11ZR Xplained Pro kit can be powered by several power sources as listed in the table below.
Table 3-4. Power Sources for SAM B11ZR Xplained Pro
Power input Voltage requirements Current requirements Connector marking
External power 5V ±2% (±100 mV) for
USB host operation.
4.3V to 5.5V if USB host
operation is not
required. Recommended
minimum is 1A to be
able to provide enough
current for connected
USB devices and the
board itself.
Recommended
maximum is 2A due to
the input protection
maximum current
specification. PWR
Embedded debugger
USB 4.4V to 5.25V (according
to USB spec.) 500 mA (according to
USB spec.) DEBUG USB
Battery header is another power input, refer to Battery Header .
The kit will automatically detect which power sources are available and choose which one to use
according to the following priority:
1. External power.
2. Embedded Debugger USB.
Note: The selection for the supply of the Target MCU has a separate connector. The above priority
selects which supply is used to power the EDBG and the VCC_P3V3_CON.
Info: External power is required when 500mA from a USB connector is not enough to power
the board with possible extension boards. A connected USB device in a USB host application
might easily exceed this limit.
