10ZiG 44xx: Hardware 

10ZiG 44xx thin client

This 10ZiG thin client is a small neat unit. My example is a 4448C Zero Client. These are about the size of the old Clientron U700 and U800 series thin clients. The publicity blurb says:

The 4400 Series Thin Client is the 10ZiG value class offering. Running on an Intel 1.33GHz Dual Core processor, it's the perfect hardware for task-based workers and breaks benchmarks set by previous 10ZiG value/enterprise hardware. Offering Dual Screen capability as standard and VESA mountable steel casing, this small form factor hardware is a serious choice for business and task users. This is the most economical, energy and space saving hardware 10ZiG offers, yet still provides high-performance multimedia acceleration. The 4400 Series Thin Client is available with 10ZiG PeakOS (Linux), Windows Embedded 7 (WES7), Windows Embedded 8 (WE8S), and Windows 10 IoT (W10 IoT) and is VMware, Citrix & Microsoft Ready.

I think the 44xx Thin Client series were launched around July 2015 and the Zero Client 4448C in May 2016. At the time of writing (May 2018) they are still current products.

A copy of the datasheet is here.

I've seen mention of the following thin client models:

ModelOSRAM (std/max)Storage

I have the 4448C which is billed as a Zero Client and came with 4GB of flash and 2GB of RAM.

Power Supply

The unit requires a 12V supply and uses a conventional 5.5mm/2.1mm coax connector.

10ZiG 44xx Circuit Board As usual, clicking on the photo (right) will take you to a larger scale photo of the circuit board.

The case is compact in size so there is little space to fit anything internally that wasn't already designed to be fitted.

Flash: The standard Flash memory is not replaceable. It's a Sandisk eMMC device soldered to the rear of the circuit board. (More on that below). However there is a separate mSATA socket that can be used to add a larger SSD should you so desire.

RAM: The RAM is a conventional DDR3 SODIMM plugged into a socket fitted on the top of the board. The fitted 204-pin SODIMM was a 2GB Aplus Technology part A+NDD31333BL-2G which the Aplus site describes as a DDR3 1333MHz PC3-10600 SODIMM, 256x16 4chips 1.35V. I also tried out a 2GB PC3L part (2GB 1Rx8 DDR3L-1333 SO) from Transcend that worked, so both types are supported.

USB: There are three USB 2.0 sockets on the front panel and one 3.0 socket on the rear.

10ZiG 44xx mini-PCIe, mSATA Mini PCIe/mSATA: There are two similar sockets just below the SO-DIMM socket - the white sockets in the photo. The socket closest to the front panel is raised and what ever is plugged in there will pass over the top of the anything fitted to the other socket. Peering at the board I can see that the upper socket is labelled mSATA whilst the lower one is labelled min PCIe.

I fitted a fairly anonymous 32GB mSATA SSD in the mSATA socket and it was duly found and mounted when I booted Tiny Core 9.0 on the unit.

Other: There is a push button on the board next to the buzzer which is labelled JBAT1. I assume that this clears the CMOS but I find it odd that this push button is located diametrically opposite the point where the battery is connected to the board.


Rear of 10zig 44xx circuit board This thin client turned out to be fitted with eMMC flash memory. eMMC stands for embedded MultiMediaCard and is the type of flash memory that is embedded in most (all?) mobile phones. This type of memory is slower and cheaper than conventional SSDs. I assume that the 'cheaper' aspect was one the reasons that 10ZiG opted to use it in this particular thin client. This is the first example I've found where the technology has been used in a Thin Client.

Looking at the back of the 4448C you can just spot the chip through one of the holes in the chassis. The device fitted to my example is a Sandisk SDIN7DP2-4G. Google found me mention of a one-off price for it of just over $5 while another supplier has it marked as obsolete.

FYI: With Linux the eMMC device does not fall into the normal sdx mass storage numbering scheme. Looking in the dmesg output you'll find:
