Hi,

There are 2 leds (TX and RX) right on top of pin 13 led (L).
What are they for?
Serial transmission seems to blink the other ones down below close to the power jack, where the 16u2 connector is.

Thanks,
RI

They're for you to use. They are connected to Due pins so that you can toggle them on/off at will. A potential use would be to blink them on canbus traffic or USB serial traffic or I2C traffic or whatever you want. It's totally up to you.

A simple forum search would have answered this question (Arduino Due pinout).. The TX led is digital pin 73 and RX 72..
