Hello,

Currently I am working on project that required a many memory. Especially Read/Write data code. I'll also will be using Create File code for this project. This project is basically reading a data and triggered another output to produce a result.

I've decided to buy Arduino Mega, SD Card Module, LCD display and keypad module. I wanted to ask what is ARM Processor. Does it have in Arduino Mega? Or maybe ARM processor is another microcontroller that is like Arduino Mega but maybe a better microcontroller compare to Arduino Mega?

Can Arduino Mega run many data? Or maybe ARM processor can do its job by running many data?

No ARM processor in an Arduino Mega.

For more information on what an ARM processor is try a Google search on;


'what is ARM Processor'


When describing a project use words that are meaningful to the forum, for instance you may know what you mean by 'many data' but I doubt anyone else does.


I well remember the day when the Worlds first ARM processor powered micro came into the LAB where I worked (we were making them) 'gosh its fast' I thought.

The SAMD21G18 microcontroller of the Arduino MKR boards is one of the common microcontrollers used in the Arduino world with an ARM core. The most reasonably priced of the MKR boards is the MKR Zero. It has a built-in SD card reader:

The MKR Zero also has significantly less IO pins than the Mega. You would probably still have enough for your LCD and keypad, but that could depend on which LCD and which keypad, so definitely check on that. The MKR Zero (and most of the other common boards with ARM core microcontrollersused by the Arduino community) runs at 3.3 V. The Mega runs at 5 V. This can make it a little more challenging to interface with the 5 V hobbyist modules that are popular with Arduino users.
