MultiWii MicroWii ATmega32U4 Flight Controller USB/BARO/ACC/MAG

MultiWii MicroWii ATmega32U4 Flight Controller USB/BARO/ACC/MAG
MultiWii MicroWii ATmega32U4 Flight Controller USB/BARO/ACC/MAG

The MicroWii is a complete multi-rotor flight controller. It is based on the ATmega32U4, which is the processor of the Arduino Leonardo. The MicroWii incorporates an MPU-6050 chip, which is a combined gyro and accelerometer plus a precise MS5611 barometer and HMC5883L magnetometer.

This is the ultimate solution for powerful flight performance with your multi-rotor project. The possibilities are endless with the MicroWii, only limited by your imagination!

Features:
• USB on chip (no FTDI or UART needed)
• Free serial port (it's possible to use a DSM2 satellite together with the GUI)
• 6 receiver inputs
• 6 high resolution (11-bit) PWM outputs
• Supports all configs up to OKTO with cam-stab support
• 2.5kB RAM
• ATmega32U4 based with Leonardo Bootloader
• 10DOF sensor array
• MPU-6050 (GYRO/ACC)
• HMC-5883L (MAG)
• MS5611-01BA03 (BARO)
• Bluetooth/GPS connector (on bottom; only GPS or DSM2 satellite can be used at one time since the 32U4 only has one UART)

Specs:
Main chip: ATmega32U4
CPU speed: 16MHz
Flash size: 32kB (3.3kB are taken by the Bootloader)
Input: 6 x high-res RX inputs (2 AUX channels)
Output: 6~8 motor outputs (motor 1-6 are 11-bit PWM)
Dimension: 50x50x16mm
Weight: 14g

Thanks. Found one. Do i connect it to the 4 pin input connector (TX0,,RX1,5V, GND) ? Or to the one with the 3 pins (3,3V, GND, Signal(RX) as shown in the manual?

I2C uses SDA, SCL, 3.3V and GND. It's best to read up on I2C bus/protocol and familiarise yourself with its inner workings.

Yeah you can connect it with a special i2c gps nav module! Can be found on ebay****

Any chance of connecting a Neo 6M GPS to this one?
 tricopterY 1139 points
Unfortunately no. Neo-6M is serial device and if you enable serial GPS in the config.h file the compiled binary file size will exceed available flash memory size (i.e around 28KB) of this FC. Your only hope is to get a GPS module with an I2C interface. Search in google for I2C-GPS Nav board and you will get some insight into how to get one and configure..

Hi Guys, Anyone had any experience with this controller? I have been trying to set mine up for the last few days. I have calibrated my RC TX - Turningy 9 channel I have calibrated my ESC's - Afro 30 Amp SimonK's I have calibrated my Acc on level surface. I can see all controls moving correctly on GUI and are centered at 1500. I have balanced my props I have plugged motors up according to the GUI Picture.. using predator 650 frame. When i goto take off it starts to lift off and then starts to pitch backs wards rather quickly :( lit its going to flip... When i hold it and move craft around it appears to fight any movements I make.... using standard PIDs supplied with this board..... Im stuck... please any advice or suggestions would be great.. PS - I have posted this here to see if anyone specifically that purchased it has any advice.. Thanks in advance!

It sounds as if the FC is not installed with the White Arrow pointing forward. The GUI should indicate that with front left motor labeled as port 6 and front right motor as port 10 etc. Just a thought.

Unfortunately, this board does not work too. If you set "# define A32U4ALLPINS" so you otherwise transform function on pins 'input'. Also in version 2.1 MultiWii not work "common setting ESC". The problem is also with the USB driver in W7 (the problem is already described on the Internet). Tile not responsible Flyduino board layout components and thus not working.

I uncommented #define FREEIMUv043 and #define A32U4ALLPINS. (the first define identifies the FC and makes sure the new sensors are all made active, and the second one clobbers all the receiver pin-outs, if you want to use all pins) The receiver inputs change from what the labels say on the board to the followings: Throttle remains Throttle, Roll becomes Yaw, Pitch becomes Aux1, Yaw becomes Pitch and Aux1 becomes Roll. I don't use Aux2, but intuitively it should remain unchanged. I am using it on a scratch built Tri-Copter and it flies very well, using the stock PIDs. The sensors on this board are really good. I am very happy with this board. Make sure you install USB driver for Leonardo, in order to be able to connect to this board on Windows.

It is a good value. But the minimalistic manual is wrong. either you do not uncomment //#define a32u4allpins or you uncomment it and connect the corresponding channels from the receiver to the Flight Control in the right order (you can watch it in the MultiWii-Config Utility). When connecting the board to PC, try to connect it to an USB 2.0 Port, not USB 3.0. That can save you a lot of trouble. My Quadrocopter is flying pretty well. Check Video 61745350 on vimeo.

Uncomment #define A32U4ALLPINS #define FREEIMUv043 and #define RCAUX2PIND17 for AUX2 It works! sequence pins from thr: thr, yaw, aux1, pitch, roll, aux2

Ho montato questa Multiwii sul x230 mini quadcopter, finalmente sono riuscito a fare funzionare tutto. Ho usato il software multiwii 2.2, per fare andare la scheda e poter usare tutti i canali bisogna attivare questi valori nel file config.h #define FREEIMUv043 // same as FREEIMUv04 with final MPU6050 (with the right ACC scale) #define FORCE_MAG_ORIENTATION(X, Y, Z) {magADC[ROLL] = X; magADC[PITCH] = Y; magADC[YAW] = Z;} #define A32U4ALLPINS #define RCAUX2PIND17 facendo questo la pinnatura dell'input della rx sarà modificata risultera la seguente partendo dal THR: Thr - Yaw (Coda) - Aux1 - Pitch (Elevatore) - Roll (Alettoni) - Aux2 Cosa molto importante è anche mettere la scheda nel verso giusto, il senso della freccia e la lettera N serigrafata sulla scheda indicano il verso di montaggio, in pratica la scheda andrà montata col connettore USB rivolto nella parte posteriore del quad, e cmq non di spigolo come altri fight controller. Prossimamente montero anche un GPS, ma adesso devo prima affinare i settari, anche se con quelli di default il quad vola gia abbastanza bene.
