Resistor
Table
The
required
resistor
for
your
desired
LED
Type
can
be
gathered
from
the
following
table.
The
values
can
be
used
both
for
operation
directly
at
a
battery
and
for
operation
at
the
AURORA
LCU
EV
2
O
.
Also
pay
attention
to
the
required
power
‐
rating
of
the
resistor.
For
choosing
the
supply,
generally
consider:
The
voltage
should
be
as
small
as
possible,
because
LEDs
do
not
need
more
than
3,5V
(red/
yellow
only
2,4V).
Everything
above
that
voltage
has
to
be
converted
into
heat
in
the
series
‐
resistor.
That
is
why
the
operation
at
3,6V/4,8V
(3s/4s
NiMh)
or
3,7V
1s
Lipo)
has
to
be
preferred.
Operating

AURORA
LCU
EV

O
Startup
Sequence
When
you
connect
the
power
supply
to
the
AURORA
LCU
EV
2
O
,
you
will
notice
the
following
behavior
of
the
6
blue
status
LEDs
:
Startup
Sequence
The
LCU
is
starting…
Now,
the
AURORA
LCU
EV
2
O
is
ready
to
operate
and
can
be
controlled
by
your
transceiver
or
for
testing
issues
also
with
a
servo
tester.
The
activation
points
of
the
outputs,
which
define
WHEN
a
output
should
be
activated,
can
be
programmed
in
the
programming
mode.
