Getting started guide

This article explains how to get started with the CM3-HOME board

What do you need to start ?

The CM3-Board is available in two versions:

  • CM3-HOME-B the basic version
  • CM3-HOME-F the full features version

This guide is valid for both versions because the boards have the same PCB but on the CM3-HOME-B are mounted less components.

If you have the serial console wired the boot messages will appear on your serial terminal emulator. If you don't have the console port check the led on the ethernet connector to see if there is any activities and try to reach your board by typing:

ping raspberrypi.local

Unfortunately the standard Rasbian distribution has the ssh disabled by default so, if you don't have the serial console port you need to enable it placing the microSD on a normal Raspberry Pi and using:


If you have the serial port type this command and follow the info to enable the remote SSH access.

Run you SSH client on your PC and connect to pi@raspberrypi.local using the standard user and password:
