Hello,
What is the logic level of UART modules on i.MX 8M Mini? (1.8V or 3.3V?)
Thanks.

1.8V
From Verdin iMX8m mini datasheet:
"Due to increasing transistor density and the need for more power-efficient devices,
the I/O voltage level is trending to decrease from 3.3V to 1.8V. For this reason, the Verdin family
of SoMs supports 1.8V I/O voltage level only"
