The UPDI programming part of the ATtiny416 Xplained Nano Evaluation Kit works fine, the target UPDI AVR is powered with 5V, and it should be very convenient for stand-alone MCUs.

Now I intend to start programming in circuits powered with 3V.

What do you think, is it possible to modify the ATTINY416-XNANO?

 

 

The truth is more important than the facts.

What does the user guide tell you?

 

Have you looked at the schematics?

 

 

Top Tips:

  1. How to properly post source code - see: https://www.avrfreaks.net/comment... - also how to properly include images/pictures
  2. "Garbage" characters on a serial terminal are (almost?) invariably due to wrong baud rate - see: https://learn.sparkfun.com/tutorials/serial-communication
  3. Wrong baud rate is usually due to not running at the speed you thought; check by blinking a LED to see if you get the speed you expected

It might work, but it definitely was not intended to.  But if you found a nEDBG/Curiosity Nano in the same drawer you found that one, then you will get much better results...
