IGEL M250C 

Igel M250C thin client

The M250C is one of the several hardware models that have underpinned Igel's UD2 series of thin clients. I believe it was launched in May 2019. Last sales were in December 2022 and support ends in December 2025. It came in various configurations.

UD2- LX 50:

  • Intel Atom x5-E8000 Quad-Core 1.04 GHz up to 2.00 GHz (turbo boost frequency) system on a chip (SoC)
  • Either 2GB or 4GB of DDR3L RAM
  • 4GB onboard eMMC

UD2-LX 51

  • Intel Atom x5-E8000 Quad-Core 1.04 GHz up to 2.00 GHz (turbo boost frequency) system on a chip (SoC)
  • Either 2GB or 4GB of RAM.
  • 8GB onboard eMMC

UD2-LX 52

  • Intel Celeron N3160 Quad-Core 1.6 GHz up to 2.24 GHz (turbo boost frequency) system on a chip (SoC)
  • Either 2GB or 4GB of RAM.
  • 8GB on board eMMC

My example, pictured above, came without a foot. It was fitted with the Atom CPU, 2GB of RAM and 8GB of eMMC.

Power Supply

The IGEL D200 uses an external 12V supply with a conventional coaxial connector: 5.5mm x 2.5mm.

Disassembly

Disassembly is straight forward. Remove the two screws on the back panel and then the side panel slides back a short way and can be removed.

Expansion

Igel M250C circuit board

The motherboard is shown right. Click on the photo for a larger image.

Only the RAM in the M250C is easily replaceable.

Flash:The flash memory is either 4GB or 8GB of eMMC flash soldered to the board.

RAM:There is a single 204-pin DDR3 SODIMM socket for the RAM. The 4GB Nanya SODIMM supplied with the unit is labelled: 4GB 1Rx8 PC3L-12800S-11-12-B4.1600 and NT4GC64C88B1NS-DI The M250C data sheet says: "DDR3L-1333 SO-DIMM x 1 (up to 4GB)" (NB 4GB is the maximum that Igel fits.)

Igel M250C circuit board CMOS clear
JBAT1: There is a jumper on the board to allow the CMOS memory to be cleared.

The board is tracked for an mSATA socket but one is not fitted. I would imagine that they may well have left off other components associated with this.
