Centerm C92: Hardware 

• Hardware
• Disassembly
• Firmware
• Linux

I believe the C92 was launched back in 2015. I couldn't locate any formal announcement but the datasheet carries a 2015 copyright and Google's AI makes the same guess if asked. It is available in two forms: Dual Core CPU running WES7/WES8/COS (COS = Linux in form of Centerm OS) or a Quad Core CPU running Win 10 IOT. Needless to say my version is the dual core version. However the dual core J1800 CPU is slightly more modern than the quad core J1900 and gains 0.4GHz in clock rate.

Note: There is a mini PCIe wireless option. If fitted the rear USB socket count drops from five to four.

Power Supply

The C92 runs off 12V and uses a 5.5mm/2.5mm coax plug. The supplied PSU is a 12V 3A unit.

CPU

The CPU fitted to my example of the C92 is an Intel Celeron J1800 dual core. An alternative is the quad core J1900. Note: This is an assumption of mine. Listed in the Centerm data sheets the processor options are just identified as: 'Intel Quad-Core 2.0GHz' and 'Intel SoC Dual-Core 2.41GHz'.

Expansion

WiFi: There is a blanking plug at the top of the back panel where a WiFi aerial can be fitted. I do not know how the WiFi option is engineered but the data sheet does say the number of back-panel USB ports drops from five to four with the WiFi option.

Battery: I assume there is a backup battery located on the rear of the circuit board. Squinting through the cover I did spot some red/black wires that could be part of a plug-in battery.
