What the benefit of uploading merely hex file to avr based board like arduino uno Since the arduino ide it self will send intel hex file to the board after compile .ino file to hex file by the avrdude compiler (https://github.com/arduino/Arduino/wiki/Build-Process)?

The data is send to the bootloader, and the bootloader writes it to flash memory. Can you explain your question? What else would you want to upload to the arduino board?– JotCommented Sep 15, 2018 at 6:07

If you want to upload the same sketch to many Arduinos compiling it again and again would take much longer. Or if you create a firmware ànd don't want to disclose the source code, you can distribute it in compiled form.

ino file is not executable. it is a source code. an input for the compiler– Juraj ♦Commented Sep 16, 2018 at 5:11
