is 1.8V UART compatible with beaglebone black?

[jithu...@gmail.com]

Hi,

I want to use a 1.8V uart cable with my beaglebone black? Is it possible as typically the beaglebone supports 3.3V Uart level. I am aware that i can use a level shifter for this purpose but my application needs minimal circuitry and i dont want to use an extra level shifter for this.Is there any other possible solution for this?

Thanks in advance.

You need to use a a level shifter to prevent damaging of your uart cable.
