CP2102N Friend if no USB is plugged

Post by Markus_Gr »

Hi guys,

question to the CP2102N Friend - is it harmful if there is no USB cable plugged to the board and on the other side there are UART-signals/voltage level present on the UART interface?

The uC-Controler (Atmega 2560) working with 5V-levels for UART.


Thanks,
Markus
