2 schermen via micro-HDMI verbonden met:

• model: RaspBerry Pi 4B (DJ-hok: 8GB RAM, benedenbar: 1GB RAM)
• systeem: RaspBerry Pi OS 12 (“bookworm”)

Om te zorgen dat Maarten Zoetemeijer zelf ook posters op de schermen kan knallen gebruiken we op Android de app AndFTP en verbinden middels SFTP naar de Pi in de directory

sftp://192.168.178.9/home/pi/Pictures

Sinds de Pi op RaspBerry Pi OS 12 (“bookworm”) draait is dit niet meer nodig.
