Raspberry pi

Welcome to the Raspberry Pi Readme! This guide covers lots of topics.
From performance tweaks to network configuration, Docker setup to custom Python installation.
Let's get started and unlock the full potential of your Raspberry Pi!

Raspberry Pi OS​

sudo pacman -S rpi-imager
  • Connect your SD card to your computer and run:
rpi-imager
  • First use Erase the SD card options
  • From the settings menu, you can set the Hostname and ...
  • Select Write and wait for the process to finish
  • Connect the Raspberry Pi to your computer or router and run:
sudo nmap -sP 192.168.1.0/24 | grep -B 2 -i raspberry

Nmap scan report for 192.168.1.136
Host is up (0.00047s latency).
MAC Address: DC:A6:32:9A:EF:16 (Raspberry Pi Trading)
  • Now you can connect to your Raspberry Pi using ssh:
sudo ssh-copy-id -i .ssh/id_rsa.pub -p 22 mlibre@192.168.1.136
ssh mlibre@192.168.1.136
sudo passwd
