Table 7-2 provides the current consumption details in
various measurement conditions.
The current consumption per voltage rail and power
consumption details will be provided in the future
revision of this document.

Note 1: All current consumptions are estimates, and will be revised after initial modules are characterised.
2: The worst case maximum is when all functions are active and when the Wi-Fi is transmitting in continuous
Tx/Rx mode. This mode is used only during the Wi-Fi RF certification test. A separate software will be
required to perform this test. Power supplies should be designed with some additional derating on top of
the maximum value, typically +30%.
