Power esp32 from vin and are there vout

I got this esp32 microcontroller:

with pinout:

  1. How can I power this from vin? Can I connect 5v to the the V5 connection or is that an output?
  2. How can I get 5v out from this device and how much current can I draw from the output? If there aer any 5v output will say

5v can be applied to the 5V pin to power the ESP32 which would give a 3.3V output that can power one or 2 SPI devices. The ESP32 development board does not have a on board 5V regulator.

The ESP32 development module is not meant to be a power supply.

Ah ok. So the V5 is an input and 3v3 is an output for 3.3 v?

Kinda. The ESP32 development module is NOT a power supply. The onboard 3.3V regulator can power a few devices but not many. The ESP32's regulator is designed to provide power for the ESP32's GPIO. The more functions used by the ESP32 the more power it requires to run and the less power the regulator has for external devices. It's a balance. Oh, filter the 3.3V output, if used to power other devices, very well.
