Any reason not to get a Mega 2560

Development Tools IDE 1.x

OK ... complete newbee here ... I have never even seen an Arduino in person

I just got through reading a bunch of posts and am still a bit confused.

Is there any reason not to buy a Mega 2560 rather than an Uno R3 ?

For only a few $'s more, it looks like the Mega has more memory, more input /output pins, more PWM, ....

It also looks like it has 4 hardware serial ports rather than 1 ?

So other than having to change pin identifiers in programs written for an R3, is there any downfall to buying a Mega rather than an R3 ?

Thanks .... Mike

It's bigger.
You might get to like having more I/O pins, and find it hard to port to a Nano/Mini/Micro.

Are you talking size?

So if I wanted to at any point build a physically small project, I would have to figure out how to do more with less?

I have about a dozen projects running through my head .... I can't imagine size (if that is want you are talking about) will be a problem.

When you say "port", I assumed you mean re-write a program to work on a smaller board?

Any other reasons not to buy a Mega over an Uno?

Thanks!

Size: bigger, both physically and resources (ROM,RAM, I/O, timers..)

More often than not, I'm happier with more ESP32, Minis or Micros connected via I2C than a single Mega.

Thinking about it .... will shields made for an Uno work with a Mega ?

I tried to look ... first answer I found was "yes" ... then I found another saying "maybe" and another saying "some"

So which is it?

That might be something I should consider.
