Multiwii and Megapirate AIO Flight Controller w/FTDI (ATmega 2560) V2.0

Multiwii and Megapirate AIO Flight Controller w/FTDI  (ATmega 2560) V2.0
Multiwii and Megapirate AIO Flight Controller w/FTDI  (ATmega 2560) V2.0

This board features a multiple serial interface as well as a dedicated I2C interface. You can now plug in a GPS directly, and you still have extra ports for other external devices. In addition to that, the new ATmega 2560 has more IO pins so it can both read the PWM signal from your receiver and it has enough PWM outputs to control the ESCs directly without the need to do the PWM signal in software. 

This controller even has a MicroUSB port right on the board, no need to attach an extra FTDI USB interface.

The motion sensing side features a new generation MEMS Gyro, a MPU6050 by InvenSense, which has the MEMS Gyro / Accelerometer sensor on a single chip. There’s also a 3-axis magnetometer and a barometer sensor with a resolution of 0.01 millibar – approximately a 10 cm height difference.

Interested in GPS functionality? Well this is one of the most cost effective ways to get started - simply add a 10Hz GPS module (coming soon) and you’re good to go!

I ordered a Ublox Neo-7M GPS for my board. Once I enable gps and have wired it up is there anything else I would need to do? The baud rate is 38400. Do I just change it in audrino? The gps is listed on hk and says configured for pixhawk.

Depends on firmware you would use. For Megapirate default is 38400 and NMEA. So if you reflash FC with megapirate then gps will work out of box. For multiwii you need to enable gps port and set baud rate and protocol. (not enabled in firmware flashed by default). With MWI I'd recommend to set UBLOX protocol (more effective binary) and baud 57600 .. With UBLOX protocol settings MWI do autoconfig GPS on startup so you do not need to configure GPS separately

Running multiwii 2.2. So if in audrino I set baud to 57600 it will automatically change the gps baud to that as well? I was just playing with the setting. I don't know what port to set it to so I unchecked the option where it will find the gps when it powers up. So how would I change the baud on the gps? Do I need to buy a separate cable to redue the gps baud?

In config.h file: define GPS_SERIAL 2, define GPS_BAUD 57600, define UBLOX. Also define MAG_DECLINATION for your particular location. Refer to comments in config.h for instructions. Recompile in Arduino and upload. Serial-2 is on Molex S1-S3 (Tx2, Rx2 pins shown in the manual). You connect GPS-Tx to Serial-2 Rx and GPS-Rx to Serial-2-Tx. You must also supply 5V and GND to your GPS module from the FC.

UBLOX protocol setting is sufficient. It's activate GPS autoconfig feature in MWI firmware.

Heads up! A few posts on here mention that the USB connector is fragile. Mine broke off today while trying to calibrate the compass... I've ordered a new board but would plan to cover the connector in hot glue or epoxy resin before using it.

AAAAAAAH! The USB connector just broke off my board! I was doing a final compass calibration before the first flight! Can it be fixed? Thanks in advance....
 v_max 4037 points
if you have enough soldering skills then why not... if not... you can connect with FTDI adapter to sertial0/ftdi port.

Thanks! I gave it a good coat of looking at today.... The connections do not appear to be soldered to the board - just the USB housing itself... So, I think it might be possible to glue the housing to the board to make the connection - unfortunately, my hot glue gun broke today too... Everything takes an age to get here (in Cyprus) so today I have ordered a new board and an FTDI adapter to be on the safe side.... So near, yet so far!

For multiwii software witch modes can becobined together and witch are exclusive? i think that horizon and gpshold are working against each other.
 v_max 4037 points
It's too much to explain. Why not to read multiwii wiki? Google for "Flightmodes - MultiWii wiki" it's well described here... In general acro,angle,horizon are exlusive Others are combinable with all or with some of main modes.

Where can i get spare cabels with conectors for this board?

Search e b a y for "microjst 1.25mm pitch 4 pin" (change pin number as you need) You will find a lot

Opened up my FC today and wasnt really happy. I got someones returned board. HK didnt even take the time to remove all the the previous persons double sided tape from the back of the board. After reading all these reviews I am wondering if it is worth my time to figure out which version I have and dive in. Man those KK2 boards are making this thing look like a nightmare! All these features better be worth the time investment.

Top, no problems with it. I use it with Multiwii Software. Altitude hold, Level mode, mag, bluetooth, gps hold and return to home, all works fine with high precision. Nice Board... Altitude sensor must be covered with foam... Gps is a Locosys from a Tiny OSD 2 with serial interface, 10Hz and 112500 data transfer rate... You can use one gps modul for Flightcontroller and Osd (it needs only TX from Gps Modul)

It seems that version 2.0 doesn't have the problem of the 1.0 batch. I am using it with MegarPirateNG, NEO-6M and a bluetooth module. No problems whatsoever. If seems that HK deleted all documents in the "File" section, so search youtube for rcjoseb and you will find some great videos how to configure it. Cheers!
