Introduction
The
Multiwii_32U4_SE
is
an
All
‐
In
‐
One
Flight
‐
Controller
(FC),
usable
for
all
sizes
of
Multirotor helicopters.
It
is
equipped
with
a
microcontroller,
a
3
‐
axis
gyroscope
(GYRO),
a
3
‐
axis
accelerometer
(ACC),
a
3
‐
axismagnetometer
(MAG)
and
a
barometer
(BARO)..
The
FC
was
developed
for
use
with
the
multiWii
‐
software
(www.multiwii.com)
from
Alexandre Debus
– aka.
AlexInParis – and
it
supports
all
flight
conditions.
An
Atmel AVR
8
‐
bit
microcontroller
(MCU),the ATMEGA32U4,
is
used
on
the
32U4_SE.
This
MCU
has
6
high
‐
resolution
PWM
(ESC
signal)
outputs,
an
on
‐
chip
USB
interface
(so,
no
need
for
a
FTDI
adapter)
and
the
ability
to
read
the
signals
of
various
RX
types.
