Hello everyone!

I was going to do a small radio box for COM1 with 2 rotary encoders, 2 displays, and a push button for switching frequencies. I planned on using an Arduino Nano, as i am familiar with using this board from previous projects, and bought one because i assumed it would work with MobiFlight, but i was dissappointed it didn't . I'm now going to buy an Arduino MEGA, but it's a bit big for the box i planned on 3D Printing for the radio, and while browsing ebay for one, i found an Arduino Mega PRO-MINI, which should be the same as the regular Mega, but just to avoid another uninformed purchase, i wanted to ask the forums if this board is compatible with MobiFlight.
Here's an image of one of them:


On a side question, i was wondering: why is MobiFlight not compatible with the Arduino Nano. If it has the same Microcontroller (AtMega328) and uses the same source code as the UNO, shouldn't it be compatible, or be very easy to implement into the application?

Thanks,
Jean

Bought one from Aliexpress, waiting for its arrival, then we'll see whether it is compatible. But as Pizman said, it should be, as it's the same in its foundation.

Hi Jean,

welcome to MobiFlight!

The MEGA and the NANO might have the same µC, but the board-capabilities are different. The MEGA has a 4k EEPROM and the NANO only 1k EEPROM. Next is the Flash Memory: MEGA 256kB (minus 8kB for the bootloader) and the NANO 32kB.

If you look to the firmware you should see it has a scope of 71,650 kB. Not enough space for the NANO. I hope this answer your question.

The MEGA pro Mini has the same capabilities as the MEGA pro R3. The difference is that he is smaller (~50%) and the pins are on other locations than as the regular MEGA. The performance is the same.
So if you buy the Pro Mini be so kind to report the result.

Hi Stephan,

i will wait for slammer88's response to see if it works before buying it.
And yes, that answers my question. I have used the nano before with other programs that do the same as MobiFlight but for racing simulators and so i didn't think about the limited memory of the nano.

Thanks,
Jean

I bought the mega pro-mini and i’m happy to say it works with MobiFlight! I’m excited to see my project together. Thanks!

Great, thanks for your confirmation.

confirmed, it's working!

Thank's for the feedback!
