CRIUS MWC MultiWii SE V2.0 Standard Development Board Flight Control Module for Mini Multicopter

CRIUS MWC MultiWii SE V2.0 Standard Development Board Flight Control Module for Mini Multicopter

SE v2.0 mainly improvements:
- Optimize the layout, signal input / output interface more reasonable position;
- Replace the better performance of the gyroscope / accelerometer integrated 6-axis sensor;
- Dedicated I2C level shifting IC;
- FTDI protection designed to prevent conflicts of external power supply and USB power supply;
- With I2C (5V level) interface to connect I2C-GPS navigation pad / OLED displays and other peripherals;
- Compact size, can be installed on mini multicopter, but also by CRIUS points panels convert "standard" 45mm mounting hole spacing.

MWC firmware Profile
MWC is MultiWii Copter abbreviation, it does not mean the hardware product, but the open-source firmware.

MWC firmware supports hardware platforms
MWC firmware is written by Arduinos IDE, to support Arduinos AVR development board Pro Mini / Pro Micro / Mega etc, also support STM32 Arduinos compatible platforms, but now can not reflect the STM32 performance on any port advantages, so the AVR is still the mainstream, mature enough and stable. This product CRIUS MultiWii Standard Edition (SE) v2.0 is designed based on the Arduinos Pro Mini, use ATmega328P microcontroller.

MWC firmware supports peripherals
- Bluetooth Scheduling module - with Androids phone / tablet to debug parameters
- OLED display modules - can be used as airborne state / parameter display, but also with the remote adjust parameters
- I2C-GPS navigation board - 328P GPS autopilot can connect through it, for fixed / automatic return (next waypoint flight might have features)
- GPS - for fixed / automatic return
- OSD - FPV necessary, you can display flight control and GPS data
- Transmission module - APC2XX / Xbee / 3DR like, for ground stations function
- Optical flow module - designated flight for outdoor light is strong, the development of
- Sonar Module - for low-altitude (4 to 5 meters) high precision given flight

CRIUS launch 3 flight control, device contrast supported when running MWC
- AIOP: 1/2/4/5/6/7/8
- SE: 1/2/3/6
- Lite: 1/2/6

MWC firmware supports aircraft models
Download the latest firmware supports the following aircraft models, are free to select the desired mode in the source code and upload it to the flight control.
- GIMBAL - PTZ stabilizer independent (non-flight control purposes)
- SINGLECOPTER - VTOL uniaxial
- BICOPTER - 2 axis Avatar aircraft
- Tricopter - Y-type 3-axis
- QUADP - Classic 4-axis + mode
- QUADX - 4 axis × mode
- Y4 - Y-type 4-axis
- Y6 - Y-type 6-axis
- HEX6 - 6 axis + mode
- HEX6X - 6-axis × mode
- OCTOX8 - 8 axis × 4 mode
- OCTOFLATP - 8 axis horizontal + mode
- OCTOFLATX - 8 axis horizontal × mode
- FLYING WING - wing
- VTAIL4 - V-tail 4 axes (flight mode with × mode, shift to a more flexible, mainly as a fixed-wing to fly)
- AIRPLANE - Airplanes
- HELI_120_CCPM - Helicopter / 120 ° tilt plate, development, not recommended
- HELI_90_DEG - Helicopters / 90 ° tilt plate, development, not recommended

MWC firmware specifications for the remote control
- MWC need at least a 4-channel, 4-channel remote control but can not switch the flight mode, it is strongly recommended more than 6 channels and with at least two switching channels
- Need to have sub-trim (Sub Trim) and channel travel (ATV) adjustment function
- Need to support the fixed-wing mode (no mixing mode)

CRIUS SE Standard Edition flight control enables the following basic functions for multi-axis aircraft
- ACRO (no self-stabilizing, similar KK)
- Homeostasis
- Set high
- Lock heading
- HeadFree (headless mode, MK said "CareFree", ACM called "Simple")
- You can specify the remote control to switch channels by several basic functions of the combination, such as:
- Homeostasis + Set high + locking heading, you can control a short time off;
- Homeostasis +  Set high + fixed hover locked heading +* Can be completely de-control
- Homeostasis +  Set high + automatic return lock heading +*
With*It expressed the need to connect I2C-GPS navigation and GPS receiver board,

CRIUS SE Standard Edition flight control size parameters
- Length and width (mm): 40 × 40
- Height (mm): 11.6
- Weight (g): 9.6
- Fixing hole pitch (mm): 35mm
- Fixing hole diameter (mm): Φ3.0

Flight Control and CRIUS wiring board together, can be converted to the majority of the available rack 45mm pitch. Please note that this price does not contain wiring boards, nylon spacers / screws and other accessories.

CRIUS MultiWii SE Standard Edition v2.0 hardware feature
- ATMega328P SCM
- MPU6050 digital three-axis gyroscope and three-axis acceleration sensor (auto-use)
- BMP085 digital pressure sensor (with locking height)
- HMC5883L axis digital magnetoresistive sensors (electronic compass, locked heading use)

- Dual power indicator LED, 3.3V / 5V color is red / green
- High brightness blue LED status indicator
- Dedicated I2C level conversion IC
- FTDI interfaces with protective diode and 500mA current-limiting fuses

MWC SE flight control debugging tools and methods
- Connection FTDI, connected to the computer with a USB cable, run the GUI software tool for debugging, which is initially set to fly control (or upload firmware) must be used when the method;
- Pass-through connection Bluetooth module, with Android Phone / Tablet / PC Notebook debugging, the corresponding software tools are MultiWiiConfigurator;
- Use the onboard OLED screen can display the status of the flight control, or enter the programming mode debugging parameters;
- Connect the other data transmission module, such as a common APC2XX / 3DR / Xbee data transmission, can be connected to a PC with a GUI debugger, this is the only way to long-distance flight commissioning.
Recommended use 1/2/3

Compared with other open-source programs, MWC with an intuitive debugging method, good flight stability, the advantages of low failure rate, but we do not recommend friends  never touched multi-axis aircraft flight control directly choose this. Because MWC PID parameters is not easy tuned to perfection, and the parameters are more details to external factors, increased trouble debugging on. MWC flight control for those who prefer high cost, there is the spirit of the friends choose toss, need to have some prepared mind before you buy, it is best to have some multi-axis aircraft-related experience or knowledge accumulation. We will buy CRIUS MultiWii SE Standard Edition v1.0 friends to provide electronic flight control Settings Guide for quick installation and commissioning.
