I’ve always noticed a lag in uploading to the Arduino Due when connected to the LED board. Like, a super long delay from pressing the “upload” button to seeing anything happen in the serial monitor or on the LED board. This can be 30 seconds to minutes. I don’t know why this is. With the UNO it’s generally less than a second. The Due is the most powerful Arduino money can buy, yet it’s super slow — why?
