Clearfog[Pro]mikroBus UART 5V tolerant

[Heisath]

Hi,

 

does anyone know if the provided UART interface on the mikrobus header on the clearfog is 5V tolerant?

According to the SoC HW specifications MPP pins are not 5V tolerant.

Ok thanks for the info.

Was just wondering, because on the mikroBus Header there's also a 5V out.

 

But in the meantime I also measured the voltage on the tx pin of the clearfog and that's at max 3.3V due to pullup resistors.

So 3.3V seems like a safe choice.
