To start Chromium in kiosk mode create ~/.config/autostart/autoChromium.desktop with following contents:

[Desktop Entry]
Type=Application
Exec=/usr/bin/chromium-browser --noerrdialogs --disable-session-crashed-bubble --disable-infobars --kiosk -app=http://hcc.local
Hidden=false
X-GNOME-Autostart-enabled=true
Name[en_US]=AutoChromium

Install and enable Unclutter

Install and enable unclutter to hide mouse cursor.

sudo apt-get install unclutter

## Add this to the end of ~/.config/lxsession/LXDE-pi/autostart:
@unclutter -idle 0

Check Raspberry Pi CPU temperature

Raspberry Pi 3 CPU can get quite hot if enclosed. Use the following command to check the CPU temperature (divide by 1000).

cat /sys/class/thermal/thermal_zone0/temp

This command can be used in a script that can regularly check the CPU temperature (by means of a cron job) and shut down Pi if the temperature is above normal (75 – 80 degrees C).

Find out Raspberry Pi version

In terminal issue either of these two commands to get the model revision:

cat /proc/cpuinfo | grep 'Revision' | awk '{print $3}' | sed 's/^1000//'
awk '/^Revision/ {sub("^1000", "", $3); print $3}' /proc/cpuinfo

and find Raspberry Pi model in the following table:

Revision Release Date Model CB Revision Memory
a01040 Unknown 2 Model B 1.0 1 GB
a01041 Q1 2015 2 Model B 1.1 1 GB
a21041 Q1 2015 2 Model B 1.1 1 GB
a22042 Q3 2016 2 Model B (with BCM2837) 1.2 1 GB
a02082 Q1 2016 3 Model B 1.2 1 GB
a22082 Q1 2016 3 Model B 1.2 1 GB
a32082 Q4 2016 3 Model B 1.2 1 GB
a020d3 Q1 2018 3 Model B+ 1.3 1 GB
d03114 4 Model B 1.4 8 GB
d03115 4 Model B 1.5 8 GB

See https://elinux.org/RPi_HardwareHistory#Board_Revision_History for other models.

or get RPi version (newer Raspbian OS required):

cat /proc/device-tree/model

Restart Raspberry Pi network
