The UC-7122/7124 Series of mini size RISC-based ready-to-run
embedded computers come with the WinCE operating system
pre-installed. The embedded computers have dual 10/100 Mbps
Ethernet ports and 2 or 4 RS-232/422/485 serial ports in an ARM9 box.
In addition, the UC-7122 and UC-7124 have an internal SD socket and
one USB 2.0 host port for storage expansion, to provide high
performance communication and unlimited storage in a super compact,
palm-size box. The UC-7122 and UC-7124 are the right solutions for
embedded applications that use a lot of memory, but that must be
housed in a small physical space without sacrificing performance.

The UC-7122/7124 have built-in “ears” for attaching
the embedded computers to a wall or the inside of a
cabinet. We suggest using two screws per ear to
attach the UC-7122/7124 to a wall or cabinet. The
heads of the screws should be less than 6.0 mm in
diameter, and the shafts should be less than 3.5 mm
in diameter, as shown by the figure at the right.
