Power consumption
The following power consumption data are based on a 3.3 V power supply ,25°C
ambient temperature and measured using an internal voltage regulator.
All measurements are completed at the antenna interface without SAW
filters.
all emission data were measured in the mode of continuous emission
based on a 90% duty cycle.

Note:
Modem-sleep for applications that require CPU to remain in working condition,
such as PWM or I2S applications, etc. And while maintaining Wi-Fi connection,
If there's no data transfer, According to the 802.11 standard (e.g. U-APSD),
close the Wi-Fi Modem circuit to save electricity. For example, at DTIM3per
300 ms sleep mode andwake up 3 ms to receive AP Beacon packets, the overall
average current is about 20mA.
