Bottom view of the t180L circuit board. I was unable to access the top of the board (but see below). The top right of the board is tracked for an mSATA socket. One is fitted in my example of the Viewsonic SC-T46 (rebadged Atrust T180) but is omitted in this Atrust t180.
In July 2022 Ahson sent the pictures below of the top of the circuit board....
...which is covered by a large heatsink.
With the heatsink removed you can see the on-board RAM, the CPU and the Atrust branding.
