Two different boards...
Which one?
both,
i said i want to use the same way to connect the chips and the batteries
Still need a battery >=5V
by the way, what is the difference between using 3v pin and 5v pin as input
5V is passing through Esp voltage regulator and dropping the voltage to 3.3V.
So you loose battery capacity in the conversion.
Powering directly to 3.3V pin from 3.2V battery, there are no conversion losses.
Don't do both!

There is no 3.3V input
Look at you pinout
emmm
so can I use the 3.3v pin as input?
As long as you don't connect 5V or USB while the board is powered through 3.3V pin.
Jim, the first page in post #21 brings an interesting info:
If this is correct, 2x 3.7 Li-Ion is too much and 1x Li-Ion is enough. However, the battery should be connected at the 5V pin, not at the 3.3V one.
In general it not a good idea to connect a voltage to an OUTPUT.
Do you know what that output pin is connected to?
i found this description on another post and seems like it can be used as input
Are you using a wemos D1 mini or and esp8266 board?
OP says he/she has a ESP8266 D1 mini and wants to do the same project with the ESP32-S3-Zero.
To the ESP32 situation, I would try what the page states and feed both the ESP32 (through 5V and GND pins) and the MPU6050 with one 18650 battery.
Which LED are we talking about?
Yes you are correct.
For the one board the max input is 6V and the other says 24V but neither says anything about a 3.3V input
like this one, i cant find the exact model for you but it looks like this and it is 3mm
I agree. that Esp32 has ME6217 voltage regulator, very low dropout at moderate currents.
I can't open that website it wants me to login.
Post the datasheet here.
which one
if you mean the leds it is like this one
