This project let you upload a compiled sketch from an SD card to an Arduino through the serial port. Just like a PC uploads a sketch (except it does the Reset directly rather than using the DTR line).

Hello, we have an Arduino Mega2560 available
at https://www.mercari.com/us/item/m17664631034/?ref=search_results that comes preinstalled with a microSD flash installer while still supporting updates through SPI.

thanks ..........interesting
