Atrust t180: Hardware 

Atrust t180 Thin Client

I believe the t180 was launched back in January 2015 or maybe in the second half of 2014. It is available as the t180L (Linux) and t180W (Windows) versions. Having said that my example is a t180LB where the 'B' (standing for Base?) indicates that it is fitted with a foot that includes a Wireless Module.

It is a physically small thin client with very limited options to extend its capabilities.

This thin client is also rebadged as the Viewsonic SC-T46 but the viewsonic version has a different configuration:

 CMOS batteryFlash
Atrust t180  noneeMMC soldered in
Viewsonic t46  presentmini mSATA

I have also seen the t180 on eBay badged as a NEC US310E.


Processor & Graphics
Intel Celeron N2930 quad-core
1.83GHz (Burst 2.16GHz)
? graphics up to 1920x1200
t180L: 4GB/2GB
t180W: 16GB/4GB

2 x USB2.0 (front)
1 x USB2.0 (rear)
1 x USB3.0 (rear)
0 (Kybd and Mouse)
1 x DVI-I  1 x DVI-D
12V 3A (label)
Coax 4.8mm x 1.7mm
H x W x D (mm)143 x 39.5 x 103 (Excluding Stand)

From the N2930 datasheet: Intel HD Graphics for Intel Atom Processor Z3700 Series

The embedded operating system is either Linux or Windows. My example is the Linux version, but, contrary to the datasheet (dated October 2016), is fitted with 1GB of RAM not 2GB.

Power Supply

The t180 runs off 12V and has a 4.8mm/1.7mm coax plug. As I was writing this up I discovered that the t180 had been supplied with a 19V PSU and had apparently been running quite happily off that. It's not something that I'd recommend.


The CPU fitted to the t180 is a quad core Intel Celeron N2930.

Atrust t180 circuit board The circuit board is shown right. I haven't been able to get to the other side of the board - see the Disassembly tab for details.

Flash: The flash is provided by an eMMC chip soldered to the board. The standard 'L' size is 4GB and 16GB for the 'W' version. The datasheet does also mention manufacturing options of 32GB or 64GB.

The board is tracked for an mSATA socket (top right in the photo). See the Viewsonic SC-T46 entry for details.

RAM: Like the flash memory the RAM is also soldered to the board. The datasheet mentions 2GB (t180L) or 4GB (t180W). My t180L version came with 1GB. I guess there must have been a revision during its lifetime.

USB: There are three USB 2.0 sockets and one USB 3.0 socket. There is also an expansion socket that provides connectivity to another USB port in the (optional) expansion foot. A Wireless dongle is fitted in my t180LB.

Additional Comments

This model has no battery-backed real time clock. This is lucky as getting into it in order to replace a backup battery is not an easy task, but then again one would have hoped the case design would have been slightly different if there was a need to do this. (One could argue that Atrust discovered this problem with the t170 - which does have a battery - and their solution was just to drop the battery!)

The entry for the Viewsonic SC-T46 shows how a battery is fitted.

As reported under the firmware tab my usual USB keyboard had some issues with the t180L.
