Navio 2 UART pins logic voltage

For the UART pins, are they directly connected to the pi’s GPIO at 3.3V or are they shifted for 5V?

What is the logic of the UART port? Is it 3.3V directly from pi GPIO or shifted to 5V?

Hi @joego2124,

Welcome to our forum!

The logic levels on UART RX/TX are 3.3 V. I’ve found the old topic that might be of interest for you as well:
