7. Rock PI4 module B (option)
The RockPi4 is a single board computer that is small in size compared to other computers, but is still extremely powerful. It offers
excellent compatibility with various hardware and has an LPDDR4 RAM and a 64bit Hexacore processor. The RockPi4 is completely
integrated into the system of the monitor and can be used like that. You will receive a 32 GB microSD card for each RockPi. You can set
up an operating system on this. Ready-to-download images can be found here: https://rockpi.eu/
You can find the balenaEtcher for setting up the image on the microSD card here: https://www.balena.io/etcher/
If you have purchased a complete system with the digital signage solution from STiNO GmbH, the ready-to-use image is
already on the microSD card in the monitor.
Passive cooling within the monitor
The Rock Pi is passively cooled. This means that there is a heat sink on it that absorbs and derives the heat produced by the processor.
With passive cooling, there are no moving parts.
Connections RockPi
The Rock Pi 4 has, accessible on the side of the monitor, 2xUSB 2.0, 2xUSB
3.0 connections and 1xLAN connection (see picture). The RockPi4 is internally
connected to an HDMI port on the controller card. You can select this port
using the „Source“ button under the name „RockPi“ on your remote control.
Assembly and disassembly of the SD card
Before you insert or replace the SD card in the RockPi, switch off the device.
There is a small service flap (see picture) on the back of the monitor (bottom left).
Use a Torx10 screwdriver to remove the screws and open the flap. Below is the
card slot of the Rock Pi4. You can swap the SD card as you wish and install the
operating system you want.
Insert card:
Before you insert an SD card into the RockPi4, you have to install a
suitable operating system on the SD card. When you have done this, insert the
SD card with the label facing up into the designated card slot, then close the
service door again. Now you can switch on the device.
Remove card:
If you want to remove the SD card, make sure that the device is
switched off. You can then gently pull the SD card out with two fingers.
