Igel M330C: Hardware 


 


 

 



Igel M330C Thin Client

The M330C was once the hardware base of Igel's UD3 line of thin clients. It reached end-of-life in February 2016 but will continue to be supported through to February 2019.

M320C v M330C

In May 2016 I got hold of a M330C. From looking at the old press releases my best guess was that this hardware was launched in May 2013 as the M320C. In February 2014 the packaging (case) was changed and it became the M330C. Having now (March 2017) got hold of a M320C I see I was right.

The obvious difference is the case which was restyled. The on/off button changed from being mechanical to a touch switch. Visually the two motherboards look the same, but the M320C is marked 30D3B9C00-010B V0.2 whilst the M330C is marked 30D3C4C00-200B V1.0 so there are a few hardware revisions. One can be spotted in the lspci listings. We have for the M320C:

02:00.0 USB controller: ASMedia Technology Inc. ASM1042 SuperSpeed USB Host Controller

..being replaced by

02:00.0 USB controller: ASMedia Technology Inc. ASM1042A USB 3.0 Host Controller
...in the later M330C.

Power Supply

click for larger image

The IGEL M330C uses an external 12V supply with a conventional 5.5mm/2.1mm coaxial connector. The M330C data sheet gives it power consumption as 11W when idle and 1W in sleep mode.

Expansion

Both the Flash memory and the RAM in the M330C are easily replaceable.

Flash: The flash memory is a SATA DOM plugged into a socket - top left in the photograph.

RAM:There is a single DDR3 SODIMM socket for the RAM. The 1GB DIMM supplied with the unit is labelled: 1GB 1Rx8 DDR3 1066 SO 684445-6665 and is manufactured by Transcend. The M300C data sheet says: "DDR3 1066 SO-DIMM x 1 (up to 4 GB)"

 Mini PCI-e socket

PCI-E There is a mini PCI-e socket located under the SATA DOM. I had an AzureWave 802.11b/g/n PCI-E Mini Card to hand and plugged it in. Running the lspci command again showed a new entry:

03:00.0 Network controller: Ralink corp. RT2790 Wireless 802.11n 1T/2R PCIe

Other: CN4 and CN5 sockets There are two 4-pin sockets on the board labelled CN4 and CN5. I don't know what they are there for.

expansion On the underside of the unit is a 44-pin plug. This is for use with a connectivity module that offers wireless network connectivity and/or an additional serial port for legacy peripherals. These modules fit between the case and the foot.
