Yes as long as you’re not using another power source on the USB.

majority are 3.3V
but, if you want 5V then I would go different way:
1- the same logic but depending on what is the device you can use:
– mosfet or
– relay
to turn them on
2- check online how to control mosfet (N-Channel) or Relay – you can use the logic from what I explained in the above post – just instead of direct power from GPIO to the device, you use the GPIO to control the mosfet or relay
3- since relay takes time (ms) you might implement some delay (i.e. 100ms) once you power it on
4- before going to sleep switch GPIO to LOW to make sure mosfet or relay are off

Thanks zygfryd, that will work for 3.3v devices but what about 5v devices?

why don’t you just:
1- after sleep, enable GPIO x to which you connect DHT22 (3.3V)
2- delay 10ms
3- start everything else
4- once all is done:
– disable GPIO x
– go to sleep

The ESP8266 draws up to 350-ish mA during boot as it calibrates the WiFi, and I’d expect the ESP32 family to do the same. A 500mA regulator HT7833 or a 220-270uF low ESR capacitor on the output of the dinky little 250mA LDO regulator should solve the brownout during boot.
