MultiWii Multi-Copter Flight Control Board

The Multiwii fly control board is multicopter flight controller board that use Multiwii. MultiWii is a open source software based on Arduino to control a multirotor RC model. After years of joint efforts of many enthusiasts, and now the MultiWii program has become increasingly mature, has become very popular abroad, cost-effective flight control one.

MultiWii SE/Lite above the mainstream hardware platform with a combination of commonly used, which is equivalent to Arduino Pro Mini and 10DOF IMU sensor combined, integrated design makes working more stable flight control. You can use FTDI Basic for easy programming.

 

 

 

 

 

 

 

 

 

 

 

 

 

MultiWii SE  Hardware configuration:
*ATMEGA328P microcontroller
*ITG3205 3-axis gyroscope
*BMA180 3-axis accelerometer
*BMP085 pressure sensor
*HMC5883L 3-axis Magnetometer

 

 

 

 

 

 

 

 

 

 

 

 

 

MultiWii Lite Hardware configuration:
*ATMEGA328P microcontroller
*ITG3205 3-axis gyroscope
*ADXL345 3-axis accelerometer

Multiwii Firmware supports:
*Quadcopter, HexaCopter, Tricoprer, Y6 , Bicopter
*Two Axis Camera Gimbal,
*Acro, Level, HeadFree  flying mode
*GPS Hold , GPS Home features with additional GPS module

MultiWii SE/Lite in addition to the necessary input / output ports, but also allow a variety of expansion interfaces, can be used for OSD module, LCD liquid crystal module, Bluetooth module, the data transmission module, GPS module, satellite receiver, 3-axis head and other equipment connection. With MWC LCD module, outside the field can easily adjust the PID parameters, no longer need to carry a laptop computer.

 

 

 

 

 

 

 

 

 

 

 

 

 

Multiwii GUI operated on Linux/MAC/PC can easily observe the PID parameters, flight control signal input / output status, sensor / switch-state, as well as aircraft attitude and heading sensor signal state of each group, sufficient for the initial configuration of the aircraft easier.

GUI launch procedure:
1) You must connect the arduino board to your PC via the USB connection (the same used to inject the software via Arduino IDE)
2) Once it’s done, you can launch the GUI, and then select the good PORT COM (the same used by arduino IDE).
3) Once it’s done, you have to wait some seconds to let the arduino boot and run the soft. (wait for the LED blink)
4) once the status led is OK (it should blink ans stays off), you can press the START button to see the evolution of values.
5) you must READ the current parameters in the Arduino before configuring it. Default values are set at the beginning.The default values can be reset by uploading an old version and then the last version.
