Connecting
CROSSFIRE
Micro
receiver
V1:
The
TBS
CROSSFIRE
micro
receiver
comes
with
two
sockets.
One
is
for
BST
capability
(BlackSheep
Telemetry),
the
other
is
for
one
(1)
R/C
output
which
can
be
configured
to
either
PWM,
PPM
or
SBUS.
The
receiver
can
run
off
anything
between
4.5V
and
8.4V
and
can
either
drive
one
servo,
or
connect
to
any
PPM
or
SBUS
capable
flight
control.
Binding
the
receiver
to
the
transmitter
is
described
on
the
next
page
and
is
the
same
as
the
diversity
receiver.
V1:
CleanFlight
pilots
with
a
STM32F1
processor
board
(e.g.
Naze32
and
similar)
can
select
the
“n.i.
SBUS”
(Not-Inverted
SBUS)
to
directly
connect
to
your
FC
without
any
inverters
or
special
soldering
hacks.
Connecting
antenna
The
CROSSFIRE
system
used
regular
SMA
connectors
-
where
the
antenna
has
the
center
pin.
Connect
the
supplied
antennas
to
the
SMA
connectors
on
the
transmitter
and
receiver.
The
straight
connector
is
for
the
transmitter
and
the
other
two
for
the
diversity
receiver.
For
optimal
radio
coverage
and
range,
mount
the
receiver
antennas
perpendicular
(90°)
to
each
other.
Caution:
It
is
never
safe
to
run
a
RF
transmitting
device
without
an
antenna,
regardless
if
it
is
the
transmitter
or
receiver
as
both
function
as
transceivers
in
this
system.
The
absolute
maximum
rating
for
the
receiving
part
is
+10dBm,
so
if
you
use
high
power
settings
(>500mW
)
and
hold
the
antennas
(TX
and
RX)
very
close
together
the
RX
can
be
damaged.
