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. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
