Only starting Sympholight V5.5.17368.209, the WebUI is able to differentiate between SYMPL Core S and SYMPL Core Sp.
This is shown in WebUI > Dashboard > line "Model"
In previous versions, it is easy to differentiate on the CPU:
SYMPL Core S -> 900 MHz
SYMPL Core Sp -> 1400 MHz
The RAM is also a good indication:
SYMPL Core S -> * MB of 922 MB used
SYMPL Core Sp -> * MB of 907 MB used
Further hints:
SYMPL Core Sp has a slightly newer CPU and supports PoE in contrast to the slightly older SYMPL Core S.
For even more performance, use a SYMPL Fusion.
The print on the lid always shows the correct model:
AB447060035 SYMPL Core S
AM430280035 SYMPL Core Sp
The SYMPL Core Sp has more ventilation slots and the microSD card slot is enlarged in the middle.
In contrast, the microSD card holder in SYMPL Core S has an eject mechanism. You can push the card to eject it. This eject mechanism does not exist in SYMPL Core Sp.
