Download and install raspbian (debian for raspberry) lite package (same for PI3 and PIzero)
Raspberry Pi OS (32-bit) Lite (buster : 433M)

 wget https://downloads.raspberrypi.org/raspbian_lite_latest

 mv raspbian_lite_latest raspbian_lite_latest.zip
 ./balenaEtcher-1.5.79-x64.AppImage

Initial configuration: PI3 and PIZero can be configured headless, without a keyboard and a display.
You just need to configure the board to connect to a wifi hotspot when power on.

• Plug the memory SD card with the fresh raspbian installed.

Create file (sudo touch)

 boot/ssh

Create the file with following content (sudo vi)

 boot/wpa_supplicant.conf
 "
 ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
 update_config=1
 country=FR
 network={
   ssid="Androidxp"
   psk="pprzpprz"
 }
 network={
   ssid="pprz_router"
   key_mgmt=NONE
 }
 "

• Plug the SD memory card in the raspberry Pi and power on.
• Connect your computer to the same wifi hotspot
• Look for the Raspberry IP on the network

nmap -sn 192.168.1.0/24

• Connect to the identified IP

 ssh pi@...
 password: raspberry
