It is possible to calculate the typical current consumption based on the numbers from

total current consumption in idle mode with USART0, TIMER1, and SPI enabled, gives:
Same conditions as in example 1, but in active mode instead. From
we see that we need to add 3.3% for the USART, 4.8% for the SPI, and 2.0% for the TIMER1
module. Reading from
