Notes:

1
Note that 4 KB of the MCU's 32 KB of flash memory is used by the pre-installed USB bootloader. All 32 KB is available when programming via the ISP header rather than the bootloader.
2
For light loads. The regulator's dropout voltage increases approximately linearly with the load, from a few millivolts at no load up to around 0.9 V at 1 A.
3
Available current depends on input voltage, current consumed by the board, ambient conditions, and regulator topology. See product documentation and performance graphs for details.
