  • Installation

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
 Flash the RaspberryPi OS on a 16Gb minimum size SD

 mv raspbian_lite_latest raspbian_lite_latest.zip

  • 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
