2.4. Electromagnetic Interference
Both Armadillo-420 and Armadillo-440 have been recognized as Class A
Information Technology Equipment
[3]
under VCCI Council standards. There are
cases where this type of equipment can cause electromagnetic interference when
used in home environments. In this situation, the user may be required to take
appropriate measures to alleviate the problem.
The Armadillo-440 LCD Model (Armadillo-440 together with the LCD Expansion
Board fixed on an acrylic board) does not meet the VCCI standard and can cause
electromagnetic interference.
In order to clear Class A when using the LCD Expansion Board included in the
Armadillo-440 LCD Model, it is necessary to strengthen the ground of the expansion
board. For example, by using a metal instead of acrylic board or connecting the
fixing holes of the Armadillo-440 and the LCD Expansion Board with a wide
conducting line.
Please be aware of the following point when newly designing an expansion board which connects to the LCD interface
on Armadillo-440.
With an expansion board that includes a device that has large power use fluctuations,
such as with an audio amp, when only the GND line of the flexible flat cable (FCC)
is connected the expansion board may produce electromagnetic noise. To mitigate
the noise, strengthening of the expansion board's ground is recommended. For
example, by connecting the fixing holes of the Armadillo-440 and expansion board
by metal plate or wide conducting line.
