Notes:

1. Total combined current consumed by all power supplies: VBAT, VDD_3V3, VDD_WIFI.

2. 802.11 beacon Interval = 102.4ms, DTIM=3, Beacon Duration = 1ms @ 1Mbps.

3. MCU Stop Mode with 113µs wakeup latency (flash in deep power down mode), VDD_WIFI = 0V

4. Average current receiving 1Mbit/s UDP at 802.11n MCS7

5. Average current transmitting 1Mbit/s UDP at 802.11n MCS7

6. Wi-Fi Transmitting at +18dBm CCK 11Mbit/s with maximum duty cycle

7. Hardware capability; minimum power consumption is dependent on ZentriOS version and external components
