In terms of the No, I hoped you read the entirety of the last post, which had one modification to the idea to consider.

Do you also reject the "single RGB led output" like the freetronic LeoStick?

The above modified proposal has the same look at the original, except the pin13 led has been replaced with a RGB version.

I see about the cost now. Fair enough.

I don't know how you think it won't be used. I see it more of a 'feedback' debug mechanism, which would help in debugging, or just letting you visually identify any problems.

Perhaps we don't need it for every pin. Still I think we can do with more than one led on pin 13. How about one RGB led, like in the leostick? Good compromise?

Since we have so much more space in the arduino due to the switch to SMDs, and better wiring layout...

Would it be possible to attach a LED to every pin? I understand the problem of current draw, but try adding a IC with multiple mosfets on it. If I remember MOSFETs have huge Gate impedance, so there should be minimal to zero current draw by the mosfet switches.

If having one led for every GPIO pin is too much, then use rgb leds, so you have cover 3 pins at a time with one LED packaging.

------

In the future, it would be even better if we can have a simple indicator using small strips of eink (those 'bar' types you see in lexar flashdrives with capacity display), if I also remember for eink, they are very simple to drive directly.
