Is it possible to use an Arduino Nano or comparable as a programmer and simultaneously use it as a serial adapter?

Meaning that I would be able to flash another µC (e.g. an ATmega644PA) using avrdude + the Nano as an ISP and afterward open a terminal and view the output of my µC using the Nano as a bridge.

  • if you wire the target MCU to the Nano TX to TX then it will send to Serial Monitor over USB chip. – Juraj Jan 25 at 6:45
