Arduino UNO rev 3 or Mega 2560

Post by amarosa »

Hello, I`m beginner with arduino and the multicopters but I like to start in this hobby.
I want to make an MultiWii QuadCopter (with Wii Motion Plus + Nunchuck for more stability) , but I don´t know what Arduino board I must to buy, I have two options for a good price:

Arduino UNO rev 3 or Arduino Mega 2560 , what of the both is better and easier to use the multiwii software and connections.

I look forward to hearing from you,
Thanks!! :)

Do you plan to use a standard arduino board or a specialised flight controller (FC) e.g. from flyduino, crius, etc?
I recommend a flight controller board which can be attached to the copter more easily and is more suitable as a standard arduino board.
For example, they have 3-wire connectors for servos, speed controller, and receiver. For the standard arduino borads you have to do the cabling by your own.

Many of the flight controller boards are based upon an arduino promini. Those boards have enough pins for a quadrocopter or hexacopter without many add-ons like gps, leds, camera, gimbal. If you wish to attach a lot of those additional devices to your copter it is better to take a mega based FC.

But, you can extend a promini by buying a serial-i2c-converter based upon a second promini in order to add gps functionalities.
Furthermore, you should have a sum ppm receiver in order to save some of the spare pins of the board.

Wii Motion Plus + Nunchuck is not recommended since there are meanwhile better sensors available based upon MPU6050 or similiar.

Thanks for the information,
I think that I will use Arduino UNO Rev 3 + MPU6050 with multiwii . Is it posible?

I think that Arduino UNO is more friendly to use with another proyects (if the Arduino multicopter is too dificult for me).
I search chip MPU6050 and is better and cheaper than WM+ and NK

What is your opinion? Will works multiwii software correctly with this hardware?

I strongly support to a buy a specialised flight contoller.

You will annoy yourself after having bought a standard Uno and having attached wii motion plus and nunchuck to it ... basing your configuration upon out-dated hardware only to save a few dollars / euro...

i use a arduino mega board with a protoshield and a cheap gy80 without problems... with patience and knowledge of electronics you can do your quad... but better buy a flight controller as quadbow recommended

hi all
i have 10DOF GY80 IMU and a Arduino uno i want to connect between them and after that control quadrotor orientation with programming not RC.
please help me to connect between GY80 and Arduino uno from Multiwii.

I got the data from GY80 and saw them into the MultiWii conf GUI but i want to write some code such controller and out put PWM for 4 brushless motor by myself and dont want to use other codes of Multiwii just reading from IMU.is there any body help me???

I made a flight controller using the Arduino nano (which is same as Uno, only smaller), with GY80, you can check it out.eck it out.
