Hi,

It's time for another step in the evolution of the MEGA flight controller. Starting with the original Seeeduino Mega introduced on RCG over two years ago by kinderkram, we have more recently seen the Pro 1 and Pro 2 boards become a popular middle range choice for running either MultiWii or Mega Pirate Next Generation (MPNG).

The Witespy Pro 2.0 Flight Controller board was outfitted with new sensors and a higher quality GPS option. The boards were pre-loaded and pre-configured so that minimal knowledge was required to get flying. Other options like Bluetooth, 3DR Radio Telemetry, and a uBlox 6M GPS module could be purchased pre-configured with mating cables.

The Witespy Pro Ez3.0 Flight Controller board has everything that the Pro 2 board offers but also includes a 3.3v regulator, Spektrum Satellite receiver connection, and ALL the missing Atmega2560 I/O pins that are needed for taking full advantage of the MultiWii and MPNG feature set. The only remaining header option is for the 11 "D" outputs on the right side.

MultiWii PRO Ez3.0 Flight Controller w/ GPS Option.

The MEGA Pro 3 board has the same great sensors as Pro 2.0 board plus a separate 5v and 3.3v regulators. It also has a Spektrum Satellite receiver connection, and ALL the missing Atmega2560 I/O pins that are needed for taking full advantage of the MultiWii and MPNG feature set.

• Atmega2560 - Super fast, tons of memory
• MPU6050 Six Axis Gyro/Accelerometer
• MS5611 Barometer
• HMC5883L Magnetometer
• Servo output for camera pitch and roll control
• Supports direct connection of GPS module
• On-board USB connection for programming
• Mounting: Standard Mk style mounting holes 45mm X 45mm
• Includes: one radio r/x cable and one motor quad cable.
• Dimensions: 70x50x12mm
• Weight: 16g
• Pre-loaded with MultiWii R2.2 QUADX, and programed to fly almost out of the box with most any ESC's
• To reflash the board, using the IMU config as : //FFIMUv43

MultiWii PRO Ez3.0 Flight Controller support software is here. This includes the USB drivers, MultiWii R2.2 with GPS, and LED_Ring support.

For those of you that managed to break off the USB connector, the first diagram below shows how to get your USB back using an inexpensive FTDI adaptor.

If your MAG functionality is suffering from interference and all your efforts to reduce noise have failed, I have had success with installing my new HMC5883L Compass Module from Witespy. This appears to be the same version offered by HK but is much quicker for us to get in the US.

Unfortunately, I was not able to properly disable the on-board MAG module through a software change. This was likely due to the fact that it also uses the I2C bus with the same address. I used Van's link here for reference but merely cut out (hacker style) the on-board MAG module because I was never going to reuse it and didn't care about breaking it apart. Note that you could also use a Dremel tool, if careful to only cut the chip pins away.

The line in BOLD below must be commented out for MEGA boards like the Pro 1-3. I simply cable wrapped it to the side of my GPS board and what an amazing difference! My new MAG is now noise-free! Remember to recalibrate the MAG first with the GUI.

#if defined(FREEIMUv043) || defined(MICROWII)
#define MPU6050
#define HMC5883
#define MS561101BA
#define ACC_ORIENTATION(X, Y, Z) {accADC[ROLL] = -X; accADC[PITCH] = -Y; accADC[YAW] = Z;}
#define GYRO_ORIENTATION(X, Y, Z) {gyroADC[ROLL] = Y; gyroADC[PITCH] = -X; gyroADC[YAW] = -Z;}
#define MAG_ORIENTATION(X, Y, Z) {magADC[ROLL] = X; magADC[PITCH] = Y; magADC[YAW] = -Z;}
//#define MPU6050_I2C_AUX_MASTER // MAG connected to the AUX I2C bus of MPU6050
#undef INTERNAL_I2C_PULLUPS
#endif

I made up my own cable to connect the external Compass Module to the I2C connector with the 3.3v supply. It is not recommended to use the 5v supply although others have tried it successfully. Perhaps Paul will have a new cable made for connecting the external Compass Module to the Pro 3 board.

I hope this board will take some of the fear out of MWC, and get more people in the air faster and at a great price.

The Mega Ez3 has simple to use connection cables for plug and play GPS, Bluetooth,LED RING, OLED, Rx,and motors esc. but has the flexibility to be easily installed, or use more the one system.

For the Rx connection. you have the the Ez connection cable. Direct Spectrum satellite connection, S.bus, and PPM sum headers.

at what point will these 8 bit cpus be ancient enough?

Of course I see this, only hours after spending all my money on an APM 2.5

This board looks awesome.

very good!
it s a good new to see a real improvement about our fc for multiwii
the only thing that you should consider,is to put compass on the gps module and not on the board!!
we will have better results with gps features...if it will be the case,you board will be perfect and many people will not have problem with their compass

Release Date? Never mind must have populated over night. Great Price BTW!

Hi everyone. A newbie question. Want to get a FC for my next F450 build. Am enjoying my Flip RTF and an Ecks frame Kk2 acro quad. What would the Mega Pro 3.0 offer that the Flip FC with GPS pod doesn't?

you will have more input/output....
now for the price(if it s already the same price for the v3 than v2) you should go for the v3
for me the spektrum port is a GREAT thing and i am very happy to see it
only compass on the baord is not good in my point of view...this board is almost perfect
if the price is still the same(or a bit more),crius aio pro will have problem

quad007,

Remember this is a "middle ground" flight controller. You have other options if you want more processing power. Wait until you see the price!

titeuf007,

I agree that I would love to see the compass on the GPS board like the DJI products. Sometimes it is difficult to get the board sufficiently high to avoid the magnetic fields of the MRC.

HeliCopCR1,

The boards are in stock so you can order them here.

cruiser73,

The Pro 3 board has a MS5611 Barometer, HMC5883L Magnetometer, and a servo output for camera pitch and roll control regardless of motor count.

As titeuf007 mentioned, you have much more I/O that you can interface with all at once without limiting your options. The ATmega328 is replaced by the Atmega2560 which has much more memory so you run MPNG, if desired.

Thanks Titeuf. The price on the website is $50+$30 for the GPS. This would be a good FC for practising AP with the GPS option, I think😊

Cheers Greg. Will probably go for this FC with GPS instead of the Flip with GPS and CC3D (the two FCs I had short listed).

About time! its been awhile lol
