Hardware Overview

Power Consumption

The following table defines the power consumption specifications for the Micro in various
states of operation. See

Power Management

for details.

These nominal values should be used to calculate metrics such as battery life. To
determine the absolute maximum DC power that would be required under any condition,
one must consider temperature, channel of operation, and antenna return loss.

Note:

1 - Power consumption is defined for TTL UART

operation. Power consumption may vary if the USB
interface is connected.

Note:

2 - Power consumption is defined for operation into a

17dB return loss load or better. Power consumption
may increase, up to TBD, during operation into
return losses worse than 17dB and high ambient
temperatures.
