Dimension of the pins of ESP32 Modules

Hello,
I posted by mistake the same question on the GENERAL DISCUSSION forum, but i believe here it is the best place to be.

I bought and used in a project ESP32-DEVKITC-32U module from Digikey.
It is a 38 pins module with 1 inch spacing between the two rows and antenna is pcb antenna, extended from the top of the module.
I have the EAGLE library for schematic and pcb module, but i am looking for something different.
I want to know the PHYSICAL dimensions of one pin. Not the size of the hole for pcb.
It looks like the pins are rectangular or square.
I want to know the dimension of the two size of the pin.
I need to find a type of SIP female connector, and using two soldered on the pcb i can PLUG and REMOVE the module from the board.
I did not find any data sheet where are listed the size of the pins of the module like you read for example on regular IC.
Please help.
Thank you very much.

Hi,

I've deleted the last post. Let's keep just one!

This is very standard pin header.

Thank you ESP_Minatel.
Now i can look for a SIP which can accommodate this size of pins.
As i said, i want to solder TWO SIP 19 pins, at 1" spacing, and use them as a socket for the module.
So i can plug or remove the module from the pcb, without soldering to the board. Like the old sockets for dip IC before SMT.
I believe, Mill-Max have sip sockets which accommodate square pins 0.025x0.025 inch.
